It has been ages since the military has been using GPS to monitor the enemy and ascertain locations that are important for their operations. GPS vehicle tracking technology is crucial to operations where the military needs to scout and locate places that will not be found on any major mapping devices.
GPS tracking is critical to the military as it can identify the type of vehicles used by the enemy and get their exact location within seconds. With this level of timely and detailed information, the chances of completing an operation successfully are very high.
GPS tracking systems are very beneficial to police officers, too. One of the reasons is because police officers can use GPS tracking to keep tab of suspects and fugitives. They can keep track of the location of the vehicle they are pursuing without being discovered by the suspects. Also, with GPS vehicle tracking, police officers can get to the perpetrator’s location without engaging in a dangerous high-speed pursuit through crowded neighborhoods and along busy highways. A GPS tracking device is a great tool for police enforcement in the event of lost or missing vehicles and their potentially expensive cargo.
GPS based vehicle tracking is also useful for ordinary folks like you and I. It can be used for personal and commercial use. In our high-tech world, this system has become one of the best inventions that assist us with our daily tasks. Almost all drivers are grateful for their GPS vehicle tracking systems. With the GPS tracking system, fleet owners and managers are now able to track their vehicles effectively. This is the main idea and rationale behind the GPS vehicle tracking system. When fleet owners and managers need to locate their employees and vehicles urgently, they can rely on the GPS tracking system to get the job done.
GPS Vehicle Tracking Has Additional Purposes
Many people who use a GPS system as a form of anti-theft device. Should there be any unauthorized movement of the vehicle, some of these devices may have the capability to disable the vehicle’s engine. With a GPS system installed in the vehicle, car owners can have piece of mind.
There are people who use GPS tracking to keep track of some important people in their lives or of their vehicles when they are not in town. Usually, parents will use GPS tracking to keep tab of their teenage kids should they attempt to drive the family car. Although it may seem like prying, in some cases, the caution is warranted.
GPS vehicle tracking technology offers all owners of vehicles peace of mind. Although this comes at a cost, in most cases the vehicles or the cargo they carry or the people they transport are worth every single cent paid for this technology.
A Variety Of GPS Tracking Systems For Different Needs
There are many different kinds of GPS vehicle tracking systems. Some are more suited for personal use; others for business users. Some examples of GPS vehicle tracking system are:
1) Wireless GPS tracking system
This system allows you to get quick and simple access to all the crucial information that you need. The footprint for this system can be extensive. The GPS tracking software delivers thorough fleet tracking and data reporting automatically.
2) Entry-level GPS tracking unit
The difference between a wireless GPS tracking system and an entry-level GPS tracking unit is that it is customized for fleets that have basic vehicle tracking needs, like vehicle location, speed, stops and route.
3) Advanced GPS tracking system
This system is equipped with “real time” tracking which is meant for larger company fleets which delivers detailed historical information.
Buying A GPS Vehicle Tracking System
It is not too difficult to find a retailer that provides GPS tracking systems and related services. Some retailers are better than others. The better ones have experts who actually use the products they sell and give expert advice regarding the features and functions of the devices that they sell. Others will have also quality customer services to handle any user queries regarding the products that they have purchased. Advanced Tracking Technologies, Inc. (ATTI) is one of the most popular places to such systems since they stock a wide range of different kinds of GPS vehicle tracking systems at reasonable prices. Moreover, they provide useful information on their different products and the most suitable ways to use them.

1) Aids them to reduce operating costs and also handle their mobile assets effectively.
2) They help to minimize increasing fleet expenses.
3) Increase fleet efficiency, decrease car and truck operating costs,
4) Decrease time taken at unauthorized locations and track the activities in a competent way.

Anyone who has used a great GPS system, including a great motorcycle GPS system, will know how user friendly and useful a good GPS can be. With modern GPS technology coming of age and modern digital mapping technology improving, a great motorcycle GPS can turn a ride into a pleasure. What is GPS? For those who don’t know, GPS stands for Global Positioning System. It is a navigation and positioning technology pioneered by the US army, that has been taken to it’s ultimate and turned into a complete user friendly modern navigation solution. Whilst in the past GPS was really just the province of the military, the technology is now so good, and so cheap, that anyone needing the ultimate in navigation can afford it. That includes motorcyclists, modern motorcycle GPS has also come of age. Basically GPS works by cross referencing the signals from a number of satellites above the head of the user and using those references to plot the user’s position on the globe. It will only work where there are available satellites, so if you can’t pick up the signals your GPS won’t work. Modern GPS is accurate, depending on the number of satellites available, to within less than a yard. So anyone seeking to navigate by use of a GPS system can obtain extremely accurate positioning. And this is now user friendly. In the past this information was only available as a longitude and latitude figure. This was only really useful to someone with the technical expertise to actually use this to plot the position on a map. However now modern GPS, including high quality motorcycle GPS systems, can combine digital mapping technology with GPS positioning to produce an extremely user friendly outcome. Basically the position plotted by the GPS can be overlaid onto a digital map to show the GPS user, including the motorcyclist, their exact position on a digital map, and tell them how to get from where they are to where they want to go. So motorcyclists can now buy dedicated motorcycle GPS systems that they can use as a total navigation system. There are various ways they can do this. It’s quite possible for the motorcycle rider, who may also, for example, be a keen hiker, to get a handheld portable GPS unit that can be taken anywhere, including mounted on a motorcycle. Download and install some maps that cover the area you want to navigate in and portable GPS can be used by just about anyone just about anywhere. There are, however, some drawbacks using portable GPS for a motorcycle GPS system. When mounted on a motorcycle a GPS unit needs some special qualities. It needs to be vibration resistant, as a motorcycle has vibrations. It needs to be weather resistant as any equipment on a motorcycle will be out in the weather, including the rain. And it needs to be readable in all conditions, including direct sun. And a motorbike rider needs to be able to program or use it whilst wearing heavy motorcycle gloves. Luckily there are some excellent GPS manufacturers who have come to the rescue of the motorcyclist by manufacturing dedicated motorcycle GPS systems that combine all these features and more. The GPS mounts are designed to allow mounting without the problems of vibration, and the GPS units are vibration resistant, waterproof and can be read, and used, by the motorcyclist. And even better, the best motorcycle GPS units can be used without the need for reading the screen. With bluetooth technology built in they can send directions by voice direct to the helmet of the motorbike rider, so the rider doesn’t need to take his eyes off the road. Program in where you want to ride and it will take you there every turn, turn by turn. Ask it to and it will tell you all the places of interest along the way, like food or fuel stops, and accommodation. With the right extras it will even tell you in real time where the traffic jams are and how to ride around them. This saves you both time and fuel. And along the way your motorcycle GPS unit may even allow you to play your favorite music or do the odd phone call or three. And a good motorcycle GPS system should set you back less than $1000. It’s money extremely well spent for a motorcyclist who likes long, hassle free rides. So if you ride a motorbike, and have a lazy $1000, you can’t do better than spending it on a quality motorcycle GPS system. It will repay you over and over.

GPS antennas are an important part of all wireless systems. The GPS antenna works by combining a planar antenna and a frequency converter, which converts the high frequency phase modulated spread spectrum by the GPS system to an intermediate frequency. Today you can find many types and brands of GPS antenna available on the market. You can choose which is best for your own personal or business needs. Can you detail on the Internet about the different models available and choose the one that suits your needs and your budget. Some of the most important reasons to consider including a GPS antenna: 1) For use in car or other vehicle when the GPS device can not or will not be placed near a window 2) For use when hiking or walking in difficult geographical areas, such as the jungle canyons 3) For use in highly developed areas such as downtowns 4) For use in any location where GPS is not a good line of sight towards the sky 5) To minimize the use in a moving vehicle in a temporary loss of signal 6) To improve the best accuracy of the GPS signal with a lock on the number of GPS satellites In fact, here specifically for pilotage services, a number of advantages in the use of the GPS antenna: 1) Reduction of flight time With a GPS antenna, it is possible for a driver to reduce the turnaround time of the plane about five minutes for as low as one minute. 2) improving the efficiency As the air constantly commuted to maintain a constant phase lock with GPS stations, no flight time is wasted waiting for the lost lock on GPS signals. In addition, it also reduces costs by reducing the total flight time of execution. Without doubt, one GPS antenna provides increased efficiency. 3) Minimum investment required Because the technology is based on commercially available components, only a minimal investment is required. A low cost and stable GPS antenna can be added to any existing vehicle or airplane. In general, a GPS antenna many types of situations, regardless of the external environment around the antenna that is designed primarily for stationary applications. The GPS antenna is a high quality solution for adding GPS RF signals marine GPS navigation systems. A particular model of the GPS antenna is the Bullet III, an active antenna with 35 dB preamplifier and a dual filter bandpass. In fact, this mark has been used for many years, as demonstrated by its strength, durability and reliability. But whatever the brand of GPS antenna system, you decide to buy, after all, is that you do what you do at the right price and the expected level of reliability and durability. Get the right fit on your GPS device secure It is important to mount the GPS good to secure your GPS unit so it is less likely to be damaged.

Jeff SandersGarmin GPS Navigation http://www. GpsFrontier. 04/05/09 com GPS navigation systems have come a long way GPS systems have come a long way since they were first developed for the U.S. military. The first signal Navstar 1 was received February 22, 1978. Navstar 1 was from Vandenberg Air Force Base in California called into existence and was the first of 24 satellites, the Global Positioning System (GPS). The first generation of satellites, the Global Positioning System of 24 satellites between 22 February 1978 and October 9, 1985 have been launched. As the first operational global positioning system revolutionized the way America moves into the war and provides a GPS system in which the world relies on precise navigation. The Global Positioning System constellation of satellites in orbit is supported by the United States Air Force 50th Space Wing supported. The device is the host wing at Schriever Air Force Base, east of Colorado Springs, Colorado. You are responsible for monitoring and maintaining command and control, warning, navigation and satellite communications for Air Force Space Command and the system of global positioning satellites. Full operational capability was declared by NAVSTAR in April 1995 (NAVSTAR is an acronym for Navigation Satellite Timing and Ranging, and the government is U.S. official called the GPS satellite system). The U.S. government has awarded the Global Positioning System for civilian use in 1980 and no subscription fees or setup fees on the GPS civilian GPS market is exploding, to use, especially in the last ten years. A new generation of advanced GPS satellites to replace older satellites and there are now 34 GPS satellites in orbit, the fighting force for military and aerospace applications provide navigation aids. Civilian applications include ATMs, banking and stock exchange and power management. Currently, 31 satellites on orbit 34 are to transmit navigation signals and timing for civil and military users worldwide. GPS for civilian civilian GPS system was not always so, as now, the U.S. military still holds the most accurate positioning system available for overall national security classified. But the modernization of GPS for the two new civil signals improved the accuracy and reliability of the user, especially as regards air safety have been planned for 1998. Then May 2, 2000 “Selective Availability” was following the order in 1996 set the direction, so that users receive a GPS non-degraded signal globally and the year in 2004, QUALCOMM announced TODAY ‘Today the successful testing of assisted GPS for mobile phones, so the LED for GPS mobile phones, which are widely used today. In 2005, the first GPS satellite launched and dissemination of second civil signal to improve user productivity. Then, in September 2007, the Air Force completed a four-phase transition of the ground segment of the global positioning system to the new Architecture Evolution Plan. The substance of the debate to offer command and control of satellites and generates the navigation message for satellites to transmit the users of GPS devices to calculate their position on the earth. The new GPS satellites include new high-power, anti-jam with military precision other code, improve reliability and data integrity for civil and military users. This modernized version of the world’s largest free utility that was designed to ensure that the United States, accurate and reliable positioning, navigation and 2030 the timing function. Europe and Russia to develop its own GPS in 2004, the United States signed an agreement with the European Community on cooperation with the Galileo system planned for Europe. Galileo is a global Navigation Satellite System (GNSS), being built by the European Union and is separated from free, but the United States Global Positioning System. The European Galileo system will be operational by 2013.’s political objective is a European Community autonomous GPS that European nations may be abandoned in times of war or political differences, such as Russia and the United States could disable the use of national systems by third parties (for encryption). The Russian system GLONASS, GPS is a radio system based on satellite navigation, developed by the former Soviet Union and now operated for the Russian government of the Russian Space Forces. As the European GPS system GPS works in the Russian system separately but complementary to the U.S. System Global positioning. Russia began launching satellites for the GPS system in the area October 12, 1982 and was completed in 1995. The system has fallen rapidly in closing the collapse of the Russian economy, but in 2001 the Russian government to restore the system began with the hope of restoring global coverage by the end of 2009. GPS today, according to the GPS device with a GPS receiver requires only one signal for satellites 3-4 calculate the position and the units will operate in all weather, anywhere in the world, 24 hours a day. There are no membership fees or set up, how to operate a mobile phone and GPS receiver GPS Receiver although some additional features such as updated traffic in real time, a monthly fee, some GPS receivers like Garmin nüvi “T” series have come with a free live traffic for the lifetime of the equipment. current GPS is extremely accurate, thanks to design multi-channel parallel. Garmin 12 parallel channel receivers are quick to lock onto the satellites in the first step and they maintain strong locks, even in dense foliage or city with tall buildings, because they constantly signals up to 12 satellites at one time. Even if a receiver 12 parallel channel GPS loses the signal from 8 satellites at once, it will still work correctly. WAAS (Wide Area Augmentation System ) has been developed by the Federal Aviation Administration to extend the global positioning system to ensure accuracy to improve the integrity and availability. WAAS was originally designed to allow aircraft is the use of GPS for all phases of flight, including precision approach to the airport to leave within its coverage area. All designed to cause the air most of today’s GPS receivers are WAAS, including automotive, boating tracer and combined. WAAS uses a network of ground stations, base stations in North America and Hawaii, to measure small variations in the signals from GPS satellites. Measures of these reference stations are brought to control stations and then send correction messages WAAS geostationary satellite. satellites then transmit the correction messages to Earth, where WAAS GPS receiver to use the correct data while computing their positions to improve accuracy. WAAS GPS receiver with an accuracy of 3 meters and they are accurate GPS receivers for civilian use on the market today. In fact, a WAAS GPS receiver can also show you the path towards your car traveling (as long as the mapping program supports the “Lane Assist” sense) and requires no additional equipment or fees to take advantage of WAAS GPS receiver, they are still as common as mobile phones.

TECHNOLOGY WAAS
GARMIN

DESCRIPTION

Surely they have heard of WAAS, and its improvements in the field of navigation and location … But what is the technology WAAS. It is an improved tracking system that allows us to have a greater accuracy in determining a GPS position.

The current accuracy of GPS equipment, is approximately 15 meters, so always Cuena a significant position error. Now with the new devices WAAS-enabled GPS navigation, such precision in position, is reduced to within 3 meters.

? 100 m: original GPS system (with SA).

? 15 m: current GPS system (without SA).

? 3-5 m: System Differential GPS (DGPS).

? <3 meters: Typical WAAS Accuracy

ORIGIN:

The origins of WAAS technology, arose from the need for greater precision in the landing of aircraft. This technology is being developed by the Federal Aviation Administration (FAA) and Department of Transportation (DOT).

Because GPS technology, did not cover the needs of accuracy, WAAS technology is created, a correction on the GPS signal. This correction is necessary, because of atmospheric disturbances produced in the ionosphere, possible errors in the satellite orbit.

OPERATION:

WAAS consists of approximately 25 points of land, which monitor the GPS satellites, and the data they send, over the territory of the United States.
Two master stations, collect data from reference stations and by contrast, creates an error report that you can have the GPS signal and send it to recipients who have WAAS capability. This is done through satellites on Ecuador, or geostationary satellites. Automatically, on the devices themselves, the signal is corrected, and thus, the accuracy increases with the receiver, and the margin of error decreases.

COVERAGE:

But today, the WAAS system is available only in North America, although its signal is usually picked up in Spain, so it is recommended that navigation systems are purchased, have this technology. Formats exist in other continents like Asia, MSAS or EGNOS in Europe, that will give us the details and appropriate corrections in the location of the WAAS.

The global positioning system (GPS for short in English), gaining more ground, more and more devices like cell phones, cameras, clocks, computers, cars use both government and business and personal use GPS technology to provide data location.

A location using GPS as a principle is to obtain geographic coordinates and location through triangulation of satellite signals. This is what makes it a universal tracking system. Whether searching for cities, streets and numbers, the GPS system for points based on a geographic reference system.

The use of GPS has great advantages, primarily knowledge anytime, anywhere on earth our exact location and altitude, that’s because our system acquires GPS coordinates and as an option can be geo-referenced in a map scale of either city, country or continent.

Of course, this is not everything, and a GPS device for navigation and exploration incorporates a trip computer data, which informs us as speed, heading toward which we are moving and the approximate time we reach our destination. In your GPS receiver you can save your important places in all times and know how to get back to them and how far they are.

This is GPS itself.

There are other systems that continue to gain ground, which have included as an essential element, a GPS receiver device. We refer to systems of automatic vehicle location (AVL). These systems are meant to know the location, speed, etc.. of a vehicle or fleet.

This require a medium of communication with his base to send location data, this could be an own radio system, a contract with the cellular network or even a satellite media. To decide on any of them, we should consider distance, cellular coverage, if there is already a system of radio communication, etc..

1. What mapping choose?
You can choose between a France that mapping core team all systems (CD-ROM for the fixed positions, embedded memory for mobile). If you do not travel outside the borders, no need to invest in a more expensive camera will offer Europe on DVD or on a hard drive larger capacity. Two providers TeleAtlas and Navteq mapping, spurred by Viamichelin in France, share the market. There is little difference between the three.

2. And if I travel in Europe?
If the answer is “often”, then choose a system whose mapping is integrated Europe. If the answer is “occasionally” choose a system that offers to download the maps via the Internet or via memory card.

3. Button, remote control, stylus or touch?
Ergonomics is one of the main qualities of a good GPS system. The choice is yours depending on your usage. The touch screen is still preferred.

4. How to read a data sheet?
- The processor speed is specified in MHz. The higher the number the higher the speed of calculation is faster and therefore more quickly you will be on track if you deviate from the route.
- The flash memory is the memory size (in MB), like a digital camera or phone. Then it is important, the mapping will be more extensive.
- See also the associated connector (USB, memory card), important for connecting other devices like cameras or MP3 player.

5. The sound quality is important?
It is essential. Do not judge a GPS quality graphics but with that voice. Indications sound you avoid leaving the eyes of the road to watch a screen size is not always compatible with driving. Some nomads, most expensive, can plug into the speakers of the car.

6. Should we choose a compact system?
It depends on usage. For frequent use, prefer fixed navigation systems, more expensive, but more responsive and better quality for guidance. For occasional use or if you change your car often, nomads are perfect. As for PDAs and other SmartphonesFew ergonomic use of the waterway must be punctual.

7. Should we choose a system scalable?
Sure. New maps, updated radar points or points of interest (POI), changing the GPS have a shelf life much longer.

8. GPS systems-they are all equipped with traffic information?
All GPS fixed offer traffic information. This is absolutely not the case for all nomads, let alone PDAs.

9. The price differences are justified?
Yes. The processor performance, storage capacity, the screen size, the number of connectors, the size of the mapping, all this is paid.

Global Positioning System, better known by its initials, GPS (for Global Positioning System) is a tracking device. Originally, this system has been designed for the U.S. military, but it was later discovered that one of the signals transmitted by the satellite could be exploited to its position on the surface of the Earth, and this, in real time. Today, many devices are equipped with a GPS: mobile phones, laptops, PDAs, automobiles, boats, motorcycles, etc.. Without discounting the GPS services, it is far from using it optimally and efficiently. Indeed, the unit can move in adding some features such as electronic guidebooks, maps or even the yellow pages services. To update the GPS, nothing could be simpler! Simply connect to the website of manufacturer of GPS and update its maps online by buying the latest updates to the device. It may also, for certain types of GPS, download the updates and install them automatically, via a USB connection. Other manufacturers have chosen instead to take advantage of GPS users of certain services, including updating maps for a few days after purchasing the device, and this for a few euros. Or subscribe to the user and to benefit from two years to update, but this is not always free, depending on the manufacturer.
