Satellite Navigation Accessories

Satellite navigation includes GPS modules, smart phones and maps used by sea and air travelers. These can come in handy especially when finding your way in streets you had never ventured through before. Smart phones have recently gained the ability to display maps via Java midlets. This makes the unfamiliar streets more accessible to one who’s new to the neighborhood thus eliminating any hassles that once existed and working to the traveler’s convenience. It also becomes easy to avoid traffic jams with these applications transmitting regular information on the conditions currently in the streets.

USB car chargers for satellite phones support a capacity of between 12 and 24 volts. You can fit them nicely in the secure cigarette lighter socket, they come in various serviceable types. One should, however, always go for a quality product and avoid dealing with bad customer service. With the home charger, the adapter plugs directly to the wall socket and your GPS pack will be charging in no while. One should always check that the charger has in-built protection

There also exists GPS services that you could use to plot your trip during a holiday. These web-based services act just like many other types of social media and allow you to meet up with great people and tour interesting sites. GPS services tend to be more robust than normal portable device operations. Satellite phones for example make it possible to make clear calls from the remotest parts of the earth.

GPS service packs are an important part of the military and nautical worlds. These have to be handled with a lot of precision as they could mean a lot of time saving on your part. Having the power supply for your digital compass die out in the middle of a voyage can be quite disconcerting leaving you in a desperate situation. These can result in a lot of inconvenience and lost man-hours at both ends.

It is always important to carry out an extra battery pack while traveling, so that your operations run smoothly in case the standby time of the original pack is exceeded. The voltage specifications should always be carefully considered while charging to avoid any blow up and unnecessary injury.

The military uses GPS devices for electrically enhanced warfare, learning of enemy positions and plotting attacks as well as planning logistics. This includes the use of RF modules to carry out coded communication in high frequency radio bands. This may include use of network of reference locations on earth broadcasting the difference as indicated by satellites and other fixed positions.

Ground based dishes can also be used in conjunction with the satellites in space for intruder detection and monitoring movement of restricted air zones as well as altitudes reserved for the armed forces. This is done through radio detection finders which utilizes the technology of electromagnetic waves for its operation. The waves transmitted by these systems emit radio waves in phases. These waves scatter in every direction when bounced off an object.

Guide to Choosing a Vehicle Tracking System

Guide to Choosing a Vehicle Tracking System

Author: Debbie Williams

Vehicle Tracking Comes of Age
Modern vehicle tracking systems are based on a combination of global positioning systems (GPS) and mobile phone technology using the internet and digital mapping to display the data in real time. Modern systems are surprisingly accurate, down to a matter of metres and available at a much lower cost than earlier technologies. Using vehicle tracking you can gather a wide variety of data to help improve your business by giving you the information you need to cut down on misuse, improve productivity, improve customer service levels and cut operating costs. So what are the steps you should follow in order to get the right system for your needs and to get the best out of your investment?

Do I need Vehicle Tracking?
When looking for a GPS vehicle tracking system the first step is to ask do I need one? Generally any company with a mobile workforce can benefit from a vehicle tracking system. However, companies who install a system and then fail to take action on the information it provides are wasting their money. So before you start, ask yourself: am I prepared to discipline people who are not performing or who are misusing company resources? Also, am I prepared to use the information to make real business changes or am I just “ticking a box?”

Be Specific
Next ask yourself, what specific results you are looking for from the system. We can all list the many benefits of vehicle tracking when, in reality, only one or two may be critical and the rest are like the features on your mobile phone - nice to know they are there, but they are not the reason you bought it. The best reasons for implementing vehicle tracking are those that revolve around improving the performance of your business rather than just saving cash. Innovative transport related employers, for example, have introduced incentive schemes that pay more when the vehicle is moving and less when parked; the result is the staff work harder without realising it. Below are some of the more common reasons for an investment in vehicle tracking:

Utilisation and Productivity: Sometimes in business we forget to ask fundamental questions like does this person need a vehicle at all? If the tracking system shows that a van leaves the depot only to ferry the driver to work and back then the system could pay for itself quite quickly. More likely, the system allows you to improve productivity.

Employee productivity: If you have a mobile work force it is important that they understand the need to use their time productively. Vehicle tracking allows you to monitor time on the road, time with customers and breaks. It can even be incorporated into the remuneration system so that it is seen as a benefit to staff, rather than a threat.

Health and safety: The employers’ duty of care means that it is vital that staff don’t put themselves in danger by excessive speed or driving for too long without breaks. Vehicle tracking allows you to monitor these factors and take corrective action to allow you to carry out your duty of care.

Contractual reasons: A service contract will be that much more enforceable if you can provide accurate data on visits to site, time spent on site and who conducted the visit. As well as proving that the service contract was fulfilled it forms an excellent knowledge base for negotiating future contracts.

Can I Rely on the Data?
If you are looking to base your remuneration system on the vehicle tracking reports then those reports must be accurate - even more so if you are looking to crack down on employee fraud. Imagine making an accusation of vehicle misuse or fuel theft only to find that the data was incorrect. That would be the last time you would be able to use the tracking system for this purpose, as it would have no credibility and neither would you as a manager. When you look at a vehicle tracking supplier ask some detailed questions about data reliability. For example, has data from their system ever been successfully presented as evidence in a civil or criminal court case?

Get a System that can be Tailored to your Needs
With prices for vehicle tracking systems coming down all the time many suppliers will not be in a position to help you get the best out of the system by customising it to your specific needs. A good example of this is the van driver that is suspected of stealing equipment from his allocated vehicle. It is possible to put a sensor on the van doors linked to the tracking system. In one case our client was able to notice that the van door was being opened regularly in the middle of the night at the driver’s home address. He had no reason to use the tools when not at a customer site and so was proven to be at fault.

Get the Managers to Manage
So much of the benefit of a vehicle tracking system is wasted because companies fail to confront errant employees. Yet this is a short-term pain avoidance measure that guarantees long-term pain in the future. You would not let staff get away with stealing petty cash or claiming for days when they were not in work, yet so many firms turn a blind eye not only to vehicle abuse, but visible vehicle abuse backed by the evidence of the vehicle tracking system. The current drive to buy vehicle tracking solely on cost is misguided as it just underpins the “fit and forget” mentality. Professional managers will understand the need to take action and the need for a reliable, accurate vehicle tracking system to underpin that action.

5 ways in which you can help aid workers in a remote environment

5 ways in which you can help aid workers in a remote environment

Author: Ian Sheldon

Aid volunteers often work in a high risk environment, be it from civilians fighting for aid or political conflict and fighting. Working in a foreign environment can often be quite a strange experience and it’s important to make the team feel at ease and as comfortable as possible so that they can concentrate on the task at hand.

There are many ways in which this can be achieved, some of which are really simple and easy to implement.

Here are 5 ways in which you could help aid workers when working in a remote, high risk environment:

1. Prepare them by educating them about their surroundings. Working in a strange place is often daunting as it is, but to work in a remote location, with people speaking a foreign language takes it to another level. Where possible provide your aid workers with maps and navigation equipment so that in the event of them getting lost they stand a chance to find their way back to base.

2. Supply them with enough food and water if they have to leave the base. But don’t just give them enough for their journey. What if they get lost or stranded? Supply them with enough rations to ensure that in the event of crisis they stand a chance of getting back to a safe place.

3. Supply them with GPS Tracking technology. With the simple use of a Motorola GPS enabled radio you can deploy a mobile tracking solution that keeps you in touch with your aid workers 24/7. Not only can you communicate with them via radio communications (should the local infrastructure allow) but you can also use the integrated GPS transmitters to track positions of the workers at all times.

4. Supply your team with suitable clothing. In some countries the weather can change in an instance. Make sure that they have suitable clothing for heavy rain or extreme heat so that they can use it when required.

5. Train them for first aid. Remote workers should always work as a team, and if one of the team is to become sick or injured its important that another member of the team is able to quickly and efficiently perform medical treatment to prevent the situation becoming worst. These are just 5 areas which touch the surface of remote working, but just by taking notice and acting on them could help to save the lifes of workers in high risk situations

How can a Car GPS review help you find the right system?

Author: Michelle_chow

Tons of reviews for practically every product can be found on the Internet in a few seconds. These reviews turn out to be a precious source for potential buyer readers. The reviews might be casually written from the author’s considerable personal experience; and they might be formally written for promoting a certain product of his own benefits; or they might be written solely for personal interests or scientific research. Readers should really be discriminative about these reviews. In order to take these reviews to their own advantage and not to be misled by falsehood reviews, it is advisable to know a few things about what makes a good review. Here let’s take car GPS review as case study to take a look at the elements of good Car GPS reviews.

Element NO.1: Highlighted pros and cons

Rather than completely boasting of certain GPS systems or completely preaching down others, a good car GPS review should emphasize the pros and cons of each GPS system. That way, readers would be reassured that they are not reading something that is written in their shoes rather than something biased.

Element NO. 2: Detailed information

Precise and accurate information about the average price of a GPS system, warranty information, what others think of this system, whether there are recalls of the products and so on.

Element NO. 3: External links

When a certain GPS system is referred, the author puts a link to where customers can get to know more about the system, or where they can buy it at a reasonable price at a right website. Also the author is quite open-minded to link some other related car GPS reviews written by someone else that might be helpful for the readers.

For a wise choice of auto GPS

Author: Michelle_chow

For a wise choice of auto GPS, there are three most important factors to be considered.

1. Technical elements

2. Map making

3. Ergonomics and navigation

Technical elements

The reception quality of GPS signal is obviously vital. Nowadays, it’s the SiRF Star III receiver that is considered to be the most excellent.

The quality of screen and graphic design. You have to verify the size, light, and anti-reflection effect. Attention, a reader GPS is often placed in the plain sunlight, so it is very necessary to have a very good light quality. On the other hand, verify if there is a night mode with less light in order not to bother the night drive. It’s also a problem of safety. The models that could be tailored to your specifications are preferred.

The sound and vocal quality. The GPS voice would accompany you throughout your trip. So it is preferable to choose a voice that pleases you. With some models you could download some other voices that are offered via internet.

The fixation. This may seems to be incidental. But there is no other thing in the world that is more annoying when GPS device falls off after a few vibrations. The angle of the screen is also a concern.

The supply. In general, a cord connects to the cigar-lighter. For those who prepare to put their navigation outside of their vehicle, they have to make sure they have a very good battery and/or they can get supply from USB cable.

Map making

The quality of map information. Are the maps offered the recent? Which territory do the maps cover? The country, Europe, or the world? The price of the device lies in the supply of these information.

The possibility of updating. Nowadays, most brands offer the possibility to update the GPS map via an Internet website. You could get different maps at variable prices, of different quality and of different updating frequency. For example, you could subscribe, purchase the updated disk drive and you could use the free version.

The radars and traffic information. The real time updated information are broadcast with one other technology concerning RDS/TMS (RDS also uses car radios to transmit text information). Two types of reception are available: integrated into GPS or through an external antenna. When you buy the GPS, you could choose whether or not to include the subscription of traffic information.

The points of interests (POI). It is about the information along your route: service station, hotels, restaurants, and others.

Ergonomics and navigation

Ergonomics is the study of working conditions, as for the workplace, intended to maximize productivity by minimizing operator fatigue and discomfort.

The ergonomics of interface. Even for a child of six years old who knows how to read and write could identify the interface and plan out a route. In any case, you could point out and validate your destination at your fingertip.

The adaption of the navigation. When GPS first appeared, the navigation voice always told you, “take a half-turn as soon as possible”. This won’t happen anymore. In fact, nowadays, the system would re-calculate the route in real time if you have not observed its instructions.

Global Positioning System (GPS)

2009-07-15T19:31:00.003-07:00

Global Positioning System (GPS)

Author: James Clark

The Global Positioning System is made up of three parts: satellites orbiting the Earth; control and monitoring stations on Earth; and the GPS receivers owned by users. The satellites broadcast signals from space that are picked up and identified by GPS receivers. The receiver takes this information and uses triangulation to calculate the user's exact location. The GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Once the user's position has been determined, the GPS unit can calculate other information, such as speed, bearing, track, trip distance, distance to destination, sunrise and sunset time and more. How accurate is GPS? Today's GPS receivers are extremely accurate, thanks to their parallel multi-channel design. However, certain atmospheric factors and other sources of error can affect the accuracy of GPS receivers. There are no subscription fees or setup charges to use GPS. Most units come with installed maps. There is a fee to update the maps and the software in the GPS. Updating can be done when needed, depending how often the maps change. Some units have an SD card to keep information on. You can also use your computer to download the information to and then transfer the data to the card. If you are in need of real time traffic data, you need a compatible unit. There is a monthly subscription fee associated with this.

Cheap GPS Units For Cars

Cheap GPS Units For Cars

Author: Neo

If you are planning to travel, but have a hard time finding a GPS unit that has features that you need, you might want to find a GPS unit that’s an affordable one.
Now that you have finally decided that you want to get the first GPS unit for your car, you might as well want to get a cheap solution that isn’t hard on your wallet but works fine at the same time. In this article, we’ll try to take a look at what features a GPS unit should have, along with a pricing guide that should give you an idea of how much a cheap device should cost you.

Most of the low-budget GPS units cost somewhere below $200 and if you see a device with a higher price, it’s not a budget GPS unit anymore. The only features that a budget GPS unit should have are: Lots of POI’s (Points of Interest) in the database (e.g. the Garmin Nuvi 205 has 6 million of them), a detour function, an easy-to-use interface and of course, a large map database that has pre-loaded maps of your area. Most of the GPS systems have an anti-theft alarm, as the trends are showing that the theft of the GPS systems has increased quite a lot as they’ve become more popular.

If possible, you should seek for a unit that has additional features. Most GPS units, even low-end ones, offer a wide variety of features that can come in handy. Some are compatible with FM and MSN traffic so you can receive live traffic reports for an additional fee. If you live in a remote area, chances are that it’s unmapped, so double-check every map that’s included with the unit; ask the seller whether or not it has maps of your location. Some of the GPS units also come with useful features like the Garmin’s "Where am I?" emergency feature – a feature, which allows to call emergency directly from the unit, save your current location in an address or locate nearby services, such as hospitals, police stations and many more.

Overall, it’s easy to get a cheap GPS unit that can be used in a car and become a proud user of a GPS unit. If you have some experience using GPS, the TomTom 125 would be a great choice, as it costs below $100 and offers a lot of features for that price category. For example, detouring isn’t missing out in TomTom 125 along with preloaded maps of the area it’s sold in. But POI’s are missing in it. However, if you have no experience using GPS devices, you should give the Garmin Nuvi 205 a try, as it’s extremely easy to use and costs just a little more than the aforementioned alternative of TomTom.

Five Misunderstandings About Car GPS

Five Misunderstandings About Car GPS

Author: Michelle_chow

People always go to extremes to take technology for granted. Information Technology might be unimaginatively amazing, but it is never too wrong to take a down-to-earth attitude towards it. Car GPS nowadays is becoming the decade’s new cosset. With the device, people get real-time traffic information and voice directions about when and where to turn. Hands-free phone calls are made possible as well. Unavoidably however, with it also come some common misconceptions.

Misunderstanding NO. 1: privacy violated

Many worried that if they use a GPS device, their car could easily be tracked by government and their privacy are violated. A little common sense of how GPS devices receive signals would disperse the misconception. As Wikipedia says about it,“ (GPS) uses a constellation of between 24 and 32 medium Earth orbit satellites that transmit precise radiowave signals, which allow GPS receivers to determine their current location, the time, and their velocity.” Although some commercial grade GPS devices send out signals about your whereabouts, consumer car GPS devices sold on the market only receive signals sent from satellites. Government has no interference with the car GPS signals and would not have any idea about our whereabouts.

Misunderstanding NO.2: weather influence

It is true that such fierce weather conditions as thunderstorm, lighting, or hurricane would have influence on the signal receiving of car GPS devices, just as TV and radio signals would be unstable under such fierce weather. However, cloudy and rainy days would do no harm to the performance of your car GPS device. The same GPS technology is used in aviation system, and airplanes can still get through clouds. It’s the same case with car GPS system.

Misunderstanding NO. 3: safety insurance

Some feel that if they have a GPS device installed in their car, they would never need to worry about getting lost or traffic jams. They think that they have invested in a life-time safety insurance. This is not true. With or without a car GPS device, a driver should be equally alert. News about GPS misleading drivers into miseries are not rare. Check up here.

Misunderstanding NO. 4: region-limited

One good thing about Car GPS device is that with proper GPS maps installed, you can get navigation from it wherever you go. Whether you are going from California to Chicago, or from Canada to China, it will work just fine. And many Car GPS devices can get you to POIs(points-of-interest) alongside the road. Wouldn’t that be exciting to take your family out to a detour with the aid of non-region-limited car GPS?

Misunderstanding NO. 5: too pricy

People with this misconception in mind are probably just intimated or mystificated by high end technology. Always believe that science and technology are developed to serve people not to make people hold awe to. Car GPS system are now available for a moderate budget, and with much more improvement it will come in handy for every car. Compared to those produced in other countries, car GPS devices from China might be a good option for those who are concerned with their wallet.

Comparison: Route 66 GPS Maps and others

2009-07-14T19:13:00.002-07:00

Comparison: Route 66 GPS Maps and others

Author: Michelle_chow

Before making a comparison between Route 66 GPS maps and other maps, let’s first make sure we know these terms.

ROUTE 66 Geographic Information Systems B.V. is a privately held company headquartered in Amsterdam, the Netherlands. ROUTE 66 specializes in navigation soft- and hardware products, and has distribution partners throughout Europe and U.S.

TomTom, a Netherlands-based maker of GPS and automotive navigation systems, is a digital mapping and routing company that focuses on car navigation and has now become one of world’s leading navigation solutions providers.

Destinator is a GPS navigation system, currently own by Intrinsyc, running on Windows Embedded CE and some mobile phone operating systems. It has a standard set of features, including turn-by-turn navigation with voice guidance, text-to-speech, pedestrian mode navigation, 2D and 3D views, local search of points of interest, integration with phone applications such as dialer and SMS, support of real-time traffic routing, speed cameras travel guide, and the ability to integrate with SNS and other LBS offerings.

PSMA , short for Power Sources Manufacturers Association, is a not-for-profit multinational power electronics association, incorporated in the state of California.

Sensis Corporation is a global provider of air defense, air traffic control, airline and airport operations management, and data integration and distribution. The company serves a global client base and is actively involved in industry organizations and working groups worldwide, helping to address critical issues and develop innovative, real-world solutions.

Compared with TomTom map, Route 66 map is slower in updating, and it is not as convenient to use as TomTom, e.g. Bluetooth function has to be started manually. But it is more excellent in some other aspects:

1. Detailed street information.

One user in Australia find that Route 66 maps offer much more detailed street information than that of TomTom and Destinator. In his neighborhood, he says, those small streets like Lennon Street in Parkville and Caprice Avenue in Port Melbourne can be found on Route 66 maps, but not on the other two maps. Although Route 66 has to make further efforts in offering much more detailed information in suburban areas, it is so far users’ first choice for detailed street information.

2. User-friendly address entry.

Users don’t have to enter the full name of a certain street. Instead, they just need to enter the first few letters of the street name, and Route 66 would automatically give them a list of street names to choose from. For example, if one wants to find “251 Salmon Street?Port Melbourne”, entering the main information “Sal 251 Melb” would just do.

3. Effective route planning and route management.

Route 66 proves itself to be a match for TomTom in this respect.

4. Fast route re-calculation.

Route 66 map system would get users re-calculate their route when they are no more than 10m off their original route.

5. Convenient phone numbers offered.

When one hits on a certain POI (points-of-interest), Route 66 map would show the company’s phone number. TomTom map does not have this function.

In summary

Route 66, taking advantage of the map sources from PSMA, offers the most detailed map information; TomTom offers wonderful route planning, but the map, drawing on Sensis sources, is not detailed enough; Destinator is detailed enough but is rather poor at route planning.

When choosing a GPS system, we should pay special attention to these three points: detailed map information, route planning quality and search database. Different from other qualities such as convenience to use and multiple functions, these three points are beyond users to make any improvement. Therefore, Route 66 might be an comparatively ideal navigation software.

What makes a perfect GPS system?

Author: Michelle_chow

There is nothing like purchasing a new product only to find that it has tons of great additional options that you didn’t know existed. It can make you feel like a kid in a candy store with $100 in your pocket. But the feeling of finding out about great options before you purchase a product can be just as fun. And for many, learning of what to expect beforehand only makes them want it more. If you’ve wanted a navigation system that serves as the perfect upgrade to the paper map then you’ll be happy to know that there are a few great ones on the market. When you’re in need of vital information that will make a difference in buying or not buying, there’s no need to sit around jabbering about how great the product is. So let’s dive right in by looking at what features a perfect GPS system should have.

Large Touchscreen

Most navigation devices come with a standard 3.5-inch screen; however, a perfect GPS features the larger 4.3-inch color TFT touchscreen. This larger size helps you to see the maps more clearly – especially when you choose to view the 2D/3D split-screen option. Additionally, being a touchscreen, you don’t have to worry about having to use a pointer to keep track up just to navigate through the system. By simply tapping the screen with your finger, you can pull up any command you desire.

Preloaded Maps and Storage Space

A perfect GPS unit also comes equipped with maps of your desired place to ensure that wherever you are in the country, you can also feel secure in knowing that you’ll be able to find your way to your destination, and back home again. It comes with 2GB internal memory to ensure that there is plenty of space for tons of maps, which also comes in handy if you want to download more maps to your device. Having this internal card available allows you to download even more maps to your device if wanted, which is a great way to expand the usability of the device and get more bang for your buck.

Text-to-Speech Voice Navigation

Another great feature of a perfect GPS device is being able to take advantage of voice navigation with text-to-speech technology. As a part of this service, you receive turn-by-turn navigation from your starting location to your destination. But you don’t have to worry about looking down at the screen for the directions because the unit will call out the streets that you need to turn onto as you approach them. This is a great feature for those who travel out of town and may run across a street without a street sign in sight.

Voice Prompted Navigation

You never know how much you appreciate guidance at every turn until you have voice-prompted, turn-by-turn navigation at your disposal. This is one of the features that comes standard in a perfect gps system. It allows you to simply type in your starting location and destination then be guided through voice instruction with every street turn or highway exit. It’s definitely a perk that will keep you from getting lost – and one that once you have, you don’t want to live without.

Integrated Radar

If you are a person who gets a bit of a lead foot when driving then you’ll appreciate the integrated radar and trip computer, both of which help to keep your speeds under control. The trip computer is a great asset because it lets you monitor the speed you are traveling, what your average speed has been on your trip, and even how soon you will likely reach your destination. And if you go over the speed limit without realizing it, the integrated radar can snap you back into reality, as it alerts you of any nearby police speed check radars.

Millions of Points of Interest

Being able to stop at any ATM, restaurant, hotel, bank, gas station, convenience store, or even amusement park in the country without first searching for this information before leaving your home may seem impossible. But with a perfect GPS system, it is not only possible, but something users do everyday. This is because they utilize the POI database that comes standard with the device. It allows you to scroll through millions of public locations throughout the country that you might be interested in visiting while on the road. Once you choose a location you want to visit, you simply select it then allow the system to guide you from where you currently are to your destination, turn by turn.

Real-Time Updates

Whether you’re on the road occasionally, or it is required that you travel very regularly for your job, it is always nice to know that you will be informed of any impending traffic situations that can hinder your travel. That is why a perfect GPS device comes in handy to so many consumers. With its ability to connect to three satellites at one time, you have the ability to receive extremely accurate updates on what’s going on with traffic in the area you’re traveling as well as real-time updates on your specific coordinates anywhere in the country.

Plug and Play Capabilities

Some navigation systems require that before you can take advantage of the product you must first register on the company’s website or download specific software. But with a perfect GPS system, you can simply pull the unit out of the box then begin using it. There is no software to download first and now annoying registration to complete. This is especially beneficial for those who are always on the road and don’t have time to get onto a computer to fulfill any extra requirements after making the initial purchase.

No Monthly Fees

Many navigation systems that offer real-time traffic updates will often tack on a monthly subscription fee to use this service. But a perfect GPS system shies away from this requirement, allowing customers to experience the freedom of using such a top-notch service with only the cost of paying for the device. This is definitely a perk that will draw consumers in the direction of this unit.

A perfect GPS system entails a perfect journey for you! Since there are so many features you can take advantage of, why not enjoy them all? Of course, enjoying them would require going out and purchasing your own. So if you want to make sure that this is the device for you, first check with owners of the product to see how much they love these features. That way, you will be able to make a more informed decision before spending your money.

The Basics of GPS: Function, Types, and Recommendation

Author: Heide Lynne Canlas

Are you bad at directions? Do you constantly get lost when traveling to other places? Then, GPS is the solution to your geographical problems!

The GPS or Global Positioning System is an electronic navigation device that makes use of a network of satellites found on the Earth’s orbit to locate specific positions and placements. Originally created for military applications, the GPS was first used by the U.S. Department of Defense. It is during the 1980’s when the US government allowed its public use.

Because it takes advantage of the satellite systems above the Earth, GPS units can be used anywhere in the world for 24 hours a day. It works in any weather condition and does not require any set-up fee or subscription charge. GPS units come in a wide variety of specifications and are manufactured by several companies. They are available in consumer electronics shop such as the Apple store and the likes.

How does a GPS work?

GPS units work by receiving information from GPS satellites that circle the earth in specific frequency. These satellites transmit information to the earth through the GPS unit or receiver, using triangulation to calculate and identify the exact location of the user. GPS receivers also compute and compare the time when the signals were transmitted and received, and such time difference also helps in locating the user’s exact position. GPS units feature a screen that serves as an electronic map where the user’s location is to be shown.

Major types of GPS

Below are the major types of GPS receivers:

1. Portable GPS. This type of GPS units is portable enough to be carried along while traveling by foot or car. However, it is not small enough to be kept inside the pocket. It typically measures 4 inches wide and weighs about 10 ounces.

2. Pocket GPS. This type of GPS unit is designed to fit inside the pocket of pants or shirt. It weight about 5 ounces, with a screen that measures 3.5 inches. It typically costs more than the portable units because of its small, slim, and lightweight feature.

3. In-Dash GPS. This type of GPS unit is built into the automobile’s dash board. It is not meant to be carried along, thus adding security to the unit and avoiding loss. More and more automobile companies offer built-in GPS units on the cars and vehicles they are selling.

4. Fitness and Cycling GPS. This type of GPS unit is especially created for people who walk, jog, run, or ride the bicycle. It is designed to fit snuggly on the wrist, just like a wrist watch. Aside from the navigation feature of the device, it can also track the athlete’s pace, distance, speed, and even calories burned.

5. Motorcycle GPS. This type of GPS unit is almost the same as that of used in cars, but is designed to fit on motorcycle consoles, waterproof, and vibration resistant. Most units come with Bluetooth hands-free technology feature.

6. Marine GPS. This type of GPS unit is specifically designed for marine use and comes with plotting functionality. It is equipped with special marine database and navigational aids such as sound signals, buoys, and day beacons among others.

Buying guide for GPS

Before buying your GPS unit from an consumer electronics shop or the Apple store, make sure you know which type best suits you and your needs. While the typical price of GPS units ranges from $100 to as much as $800 depending on the built-in features, there are other units that come with a good deal, like a few bucks off $100. Though other advanced features are tempting and useful, what’s important are the basic functionality and the ease of usability of the unit.

So before you get one yourself, make sure you have reviewed the different models and brands available and identified which unit will be of best help to you and your navigation needs.

How to choose a gps system?

Author: Michelle_chow

This time, we will give you advice about how to go about finding the gps system that will best suit your needs.

Step 1: know what’s available
Gps units come in three different types. They can be built into a car, be a part of a PDA or mobile phone, or come as a portable device (single function sat-nav device).

Step 2: How you will use it
The type of gps unit you will need depends on what sort of journeys you will be taking on the road. If you are an occasional driver who just needs to get from point A to B, a single function model by company such as garmin or magellan were good options. If you drive for a living, and your car is your office, consider buying your car with a gps in stall or installing a system into your existing car. If staying in touch with your office or emails or phone calls is important, or you spend a lot of time navigating on foot, using gps as a part of PDA or mobile phone would be the best solution.

Step 3: research the functions
As well as just a basic job of getting you from here to there, there are many more functions that a gps can perform. They can come pre-loaded with information about the roads of most countries, list places of interests, such as gas stations, or tourist attractions, receive live traffic information, and some even know speedcam locations.

Step 4: Hidden cost
The difference between entry level gps units and more expensive units like the garmin 660 are the number of features in the amount of detail provided standard. Features like live traffic information and detailed maps of foreign countries may have to be bought or subscribed to separately. You may also have to pay every few years for updated versions of your home country’s roadmap data.

Step 5: research the latest devices
Technology is constantly improving, and it’s worth checking out consuming magazines and to read about the latest gps units on the market. The first gps unit with mp3 players, such as the garmin 660, are now on sale. Knowing what is about to become available will help you decide what to buy and when.

Have a safe and air-free journey!

A GPS comparison Test: Garmin/Becker/Harmon-Kardon/Dash

Author: Michelle_chow

I have a big problem. No, not my weight. I need to get some place. I need to get from here to there. Now one option for doing that is this free paper map, which is not gonna exactly work in a car while I am driving, because that’s just not safe. Not only that, but a paper map can’t tell you where you are in relation to where you are going. Now the modern equivalent is a portable navigation device, like this garmin. In fact, we have four, a garmin, a becker, a harmon-kardon and a new dash express. We are going to find which one is best suited to your needs.

Each of these navigation devices does at least one thing well. But each is very different in its approach. They all get you where you wanna go, but some are just easier to use. The last time we review portable navigation devices, garmin was our favorite. we have to say that garmin is one of the better navigation devices, but one of the things they change is the main screen. There are now fewer icons so it’s easier to find your way around. Garmin’s nuvi 78 also has a nice big screen with clear bright graphics. Another improvement is the traffic screen. It now has more detailed and all highways are labeled.

The becker traffic assist is almost the exact opposite. And that’s not a good thing. The mount is unattractive, the menus are difficult to understand. And the maps take too long to load. We found ourselves waiting and wating, and waiting for something anything to happen. But it’s not all bad news for becker. One of the good things about the becker is that it is light and it does get you from point A to point B. However, it’s kind of confusing.

Thankfully, the harmon-kardon gps 810 isn’t the least bit confusing, even though the system is packed full of features. Plus, it’s the one system that feels like it was factory-installed. Harmon-kardon’s guiding play, who was one of our favorite systems last time we had this test because it played a lot of different media files, it still does that. But they upgraded the system with a remote control that mounts on the center council of your car. That remote makes using the harmon system very straightforward. The menus are intuitive and easier to understand. Also the harmon union has a clean looking and a simple miling mechanism.

Finally, there is an all-new navigation system from a northern California company named Dash. The dash express is basically is a portable nav system like the others. But it offers features no other system has. One of the things that is great about dash express is that traffic information is updated more quickly than other systems. In fact, they gathered information from the other dash users. So it’s more accurate and it’s more timely. The dash express has an internet connection. And that connects through a silicon singal, so rather than have a points of interest database, the dash conncects through yahoo local and you can find restaurants, bakeries, or stores. That list is almost limitless. But as revolutionary as the dash is, there are a few drawbacks. The miling mechanism is rather clunky, and the dash does not have a Bluetooth connection for your cell phone.

After our four-day of driving around, we definitely have some opinions on each one of the navigation systems. Now it turns out that each one is good, but for a dramatic different reason. For example, the Garmin is best at straightforward navigating. Plus it also has stuff like currency converter, mp3 player, picture viewer, and other features, but it’s also the most expensive. Next is the becker. And the best we can say about that is that it does get you there. Unfortunately, some of the menus are not clear, and it does have a live time traffic subscription, that’s not bad. Next the harmon-kardon is good for people to play media files, videos, or mp3s and it also plays other music files too. Plus, the remote control gives a real original equivalent feel when it is installed in your car. Finally the dash express is customer built for commuters. It gives you great traffic information and it’s up to date every one to two minutes. Plus, it has an internet search feature.

Before making a final decision however, you should figure out what your needs are, because each one of these nav systems has its strength and weaknesses. And in the end, the most expensive system isn’t necessarily the best.

TomTom Rider 2 Review: Reliable and Recommended

TomTom Rider 2 Review: Reliable and Recommended

Author: Neo

TomTom Rider 2 is a first class GPS unit, to say the least. A car mount adapter can be purchased for use in a car. It has a lot of different and even innovative features, which are all explained in the manual that is in the unit itself (the inclusion of the manual directly in the unit is itself an innovative act, by the way). Overall, it’s an awesome GPS navigator unit that falls in the low price category, but still has almost every feature needed for an average biker.

Review:
The documentation is okay, as only the setup instructions are in it, the rest is in the unit itself. After you actually set up the unit, it’s easy sailing, as everything’s easy to understand and use, as the rest of the instructions are next to the actions and you can customize almost everything on the screen when the unit is set up. The best part of it is that you don’t have to carry a manual with you all the time, as you can just put the book that came with it away and use the unit to discover everything for you.

You can load your whole address book into the unit if your phone has Bluetooth support, it’s definitely really helpful. It also allows you to make hands-free calls if you have a headset. The device is water-proof (it’s made for bikes though, so it’s not a surprise), it acquires the GPS signal really fast, and has a long battery life. The screen has great graphics and an adjustable brightness. The sensitivity of the touch screen is also nice and can be connected to your computer for ultra-fast map download. It also allows Outlook to download your contact database and the voices of map directions are okay to choose. It lacks multimedia support, compared to other models, but you can get yourself an iPod for the money you saved if you chose TomTom Rider 2.

While there are newer models than the TomTom Rider 2 that are loaded with a lot of other features, the only feature missing from this GPS unit is the lack of spoken street names when navigating. There is one but – it makes you double check everything you see -, and double-checking is a thing you should always do, as you’re probably using it on a bike. It’d be hard to find a better alternative in terms of price, functionality and quality – and it’d be hard to find a better present for a hardcore biker – a portable, easy to install and use GPS unit with a built-in visor and a touch-screen that can be used with gloves.

Features To Look For In A GPS Unit

Features To Look For In A GPS Unit

Author: Neo

It’s true that finding a GPS navigator that suits your needs can be crucial. But what if you aren’t that informed about the things that GPS navigators offer nowadays? It’s easy to make a mistake when buying them, as there are new trends each month in the GPS market and there are, of course, specific features you may want to have in your navigator. This article will try to inform you through the standard features (and more specific ones) that you may want to look for in a GPS device.

The most important feature that all GPS portables, except the really old ones, have is advanced Text-To-Speech (TTS). TTS allows you to keep your eyes on the road, as the computer-generated voice tells you specific names of locations e.g. “Turn into Abbey St. after 500m” instead of “Turn left after 500m”. This feature is crucial, as it dramatically increases driving safety and also makes your life a little bit easier because you don’t have to look at the display for street names anymore.

There are built-in maps in each GPS device, but it’s best to see what maps are inside of the GPS unit, as they’re usually sold with maps for only your part of the world (North and South Americas, Europe, Australia, etc.), that’s why it’s so important to buy one from either a local vendor or with the seller stating that the maps for your area are pre-loaded. Also, you should check whether or not the manufacturer provides updates for the maps and the way they provide them – via internet or via CD’s you’d need to purchase.

Other features are somewhat specific, e.g. if you’re traveling a lot, you may want to get a GPS that has built-in Points of Interest – restaurants and stores are shown on the map. Many GPS units come with a lot of multimedia possibilities, like the ability to watch movies, listen to music, view photos directly on the screen and even play built-in flash games; however, you should keep an eye out for the usability, as many different features don’t necessarily mean that it’s an easy to use GPS device.

All in all, the key features you should look for in a GPS device are Text-To-Speech, built-in maps with POI’s on them; other things like the size of the screen, quality and design are also very important, as the price varies a lot on them, but you should only get a GPS that has the aforementioned key features. The additional features are nice, just make sure that they don’t interfere with the usability and don’t make the device too costly. It’s easy to get lost in the endless offers of the new GPS devices, so if you find an older model that still has everything you need, get that one instead of the newer one that’s stuffed with features.

Best Marine GPS Chartplotters From Lowrance and Garmin

Best Marine GPS Chartplotters From Lowrance and Garmin

Author: Neo

If you plan going fishing or just want to go somewhere by sea, chances are that a marine GPS device might come in handy for you. In most cases you already own one that came with the yacht, however, you may want to get a better one as often the case is that many crucial features are missing on the default units, for example, a chartplotter can be of great need if you are keen on fishing. Most of the new GPS units offer echolocation, sea coordinates, but are almost always stuffed with a lot of unneeded features. In this article, we’ll try to review the two GPS chartplotters that could be deemed the best ones in the market - Garmin GPSMAP 4212 and Lowrance HDS 7, both of which have essential features that every Marine GPS should have, and also a chartplotter to receive additional data, like the speed of the boat you’re on.

Garmin GPSMAP 4212 is a GPS chartplotter that offers high-resolution satellite imagery and can boost your sea-sailing with additional awareness in any situation. It’s perfect for everyone, both for fishing or just sailing. It has an affordable price and stands out with a beautiful quality design and a 12.1” 1024x768 VGA screen. It also offers a 3D perspective of what’s below the boat, so it’s great for fishing. It is also easy to use and comes with detailed coastlines, port plans, restricted areas, gives updates of the current weather and can transmit a signal in case of an emergency.

The HDS 7 is a model that people who are keen on fishing will love, as it offers in-depth coverage of more than 100,000 bodies of water and covers most of the lakes in the U.S. in incredible detail. It is also compatible with many mapping systems and its maps are updated frequently. It is a cheaper alternative to the Garmin GPSMAP 4212 with its design being simpler than the former and the screen size being smaller, but the functions preserved. It, just as the GPSMAP 4212, also offers stereo quality reports of the weather.

The aforementioned chartplotters could arguably be the best on the market, as they offer two extremes – the focus on quality and the focus on price. Which one of them to pick remains solely to you. Just don’t forget to actually use the device on its fullest, as the features they offer are, in the worst case, very interesting, if not useful. Remember that sailing is a great way to relax, but you don’t want to spoil the fun by getting lost. A Marine GPS with a chartplotter can help you a great deal to enjoy the most of your sailing time.

Why Handheld GPS Is Useful For Hikers And Campers

Why Handheld GPS Is Useful For Hikers And Campers

Author: Neo

Most of the hikers love what they do not just because it’s good for the body and feels great, but it also provides the hiker with a strong connection with nature. Hiking and camping, both alone and in a company is a really good way to experience nature in its fullest. You probably have a lot of places where you can go hiking or camping in your area, unless you live in the Vatican or another mini-state. With that said, whenever you go camping, hiking or just to pick up mushrooms in the woods, there is always a small risk of getting injured and/or lost, but there is a cure for all that – the Global Positioning System. If you are injured, you can call someone with your cell phone, and if you are lost, you can always find your way to the nearest city or even a house that’s on a GPS map.

Many GPS devices have a built-in ability to transmit help signals, and other than that, most of them also have parallel channel receivers with a dilation of about five meters. When the GPS era first started, most of the units needed an open sky, as the signals bounced off skyscrapers and couldn’t get through trees, however, these days it’s a bit different, as most of the units are waterproof and somewhat resistant to cold, heat and outdoor weather in general, which makes the Handheld GPS units perfect for anyone with an active lifestyle.

The things you should look for in a Handheld GPS unit are much more different from the things that you would look for when choosing GPS units for cars, marine transport or planes. You shouldn’t look at the color or design of a unit if you plan to use it for hiking. The unit has to be extremely portable, durable (most of the ones that are on the market are not!) and weigh little. It should also be easy to use, as there are chances that you’ll need to use it in an extreme situation.

To sum this up, if you travel a lot, are a mountain climber, live in a remote location or are a pilot, you should have a Handheld GPS device not only for your own safety, but to keep your walking distance to a minimum, as you’ll always know the shortest road.
Remember that the best GPS for hiking is the one that has a lot of different features and offers accurate maps of the area that you want to hike.
Now pack your boots, turn on your handheld and take a walk, a longer one than you usually take, as you no longer can get lost, no matter how hard you try.

5 tips for crisis prevention when working remotely

Author: Ian Sheldon

When working abroad or in remote parts of the world, be it through serving for the armed forces or being part of an aid group, it’s unfortunate that a crisis situation might be not far away. In this situations its absolutely essential that procedures are put in place to help prevent crisis, or give the personnel involved a change to evade crisis should it occur.

Here are 5 simple tips to help remote workers in the event of a crisis:

1. Ensure that your team have up to date maps. When working in a country that is foreign to your personnel l an up to date map can help them find their way should they venture from their main routes and get lost.

2. Food and Water supply. Make sure that your team have stocked up on food and water. Dont just look at packing the bare essentials, but consider a scenario where you might be forced to stay away overnight or for a few days.

3. First Aid. Always have a first aid kit at the ready. You never know when it might be needed, even for the smallest accident. A first aid kit will help buy you some time should an unfortunate event occur within your team.

4. Clothing and footwear. When you are in a foreign country you never know when the weather might turn. It could be extremely hot one minute with a downpour of rain (and floods) the next. Be prepared for a sudden change in the weather

5. Communications. Give your team the ability to communicate with a central base within the distance of their travel. GPS Tracking can prove to be a life saving technology be it through simple tracking of personnel or communications over a radio network.

All of the above 5 points should be part of any remote teams planning and preparation when sending personnel out into the field. The welfare and safety of your team should be the absolute paramount of importance and nothing should be taken for granted. Up front planning and a well thought of crisis management plan will not only help save lives, but also give your team the confidence to go out and concentrate on their task at hand.

The Sat Nav – How it Works

The Sat Nav – How it Works

Author: Richard n Williams
The ‘sat-nav’ has revolutionised the way we travel. From taxi drivers, couriers and the family car to airliners and tanks, satellite navigation devices are now fitted in almost every vehicle as it comes off the production line. While GPS systems certainly have their flaws, they have several uses too.

Navigation is just one of the main uses of GPS but it is also employed as a source of time for GPS NTP time servers.

Being able to pin point locations from space has saved countless lives as well as making travelling to unfamiliar destinations trouble free. Satellite navigation relies on a constellation of satellites known as GNSS (Global Navigational Satellite Systems). Currently there is only one fully functioning GNSS in the world which is the Global Positioning System (GPS).

GPS is owned and run by the US military. The satellites broadcast two signals, one for the American military and one for civilian use. Originally, GPS was meant solely for the US armed forces but following an accidental shooting down of an airliner, the then President of the US Ronald Reagan opened the GPS system to the world’s population to prevent future tragedies.

GPS has a constellation of over 30 satellites. At any one time at least four of these satellites are overhead, which is the minimum number required for accurate navigation.

The GPS satellites each have onboard an atomic clock. Atomic clocks use the resonance of an atom (the vibration or frequency at particular energy states) which makes them highly accurate, not losing as much as a second in time over a million years. This incredible precision is what makes satellite navigation possible.

The satellites broadcast a signal from the onboard clock. This signal consists of the time and the position of the satellite. This signal is beamed back to earth where your car’s sat nav retrieves it. By working out how long this signal took to reach the car and triangulating four of these signals the computer in your GPS system will work out exactly where you are on the face of the world. (Four signals are used because of elevation changes – on a ‘flat’ earth only three would be required).

GPS systems can only work because of the highly precise accuracy of the atomic clocks. Because the signals are broadcast at the speed of light and accuracy of even a millisecond (a thousandth of a second) could alter the positioning calculations by 100 kilometres as light can travel nearly 100,00km each and every second –currently GPS systems are accurate to about five metres.

The atomic clocks onboard GPS systems are not just used for navigation either. Because atomic clocks are so accurate GPS makes a good source of time. NTP time servers use GPS signals to synchronize computers networks to. A NTP GPS server will receive the time signal from the GPS satellite then convert it to UTC (Coordinated Universal Time) and distribute it to all devices on a network providing highly accurate time synchronization.
