GPS tracking was at one time the domain of spies, wilderness explorers, and governments. But over the years GPS tracking has been combined with so many useful services and applications that it is commonly used in everyday life. GPS tracking has gone mainstream these days. Though it was developed years ago for military purposes, GPS tracking systems are now available to almost everyone.

The GPS tracking systems come in two different types. The first type is what they call active tracking, while the other is passive tracking. Well, each type actually takes advantage of GPS technology to provide highly accurate location reports. Perhaps the difference between these two types lies on the fact that the information is delivered in different ways.

Of the two types of GPS tracking systems, active tracking, also known as GPS real time tracking, is the most commonly used device. At its most basic, it possesses an ability to track positioning data and broadcast this data to the GPS user in real time, hence the name. Also, it is interesting to know that the GPS real time tracking systems gather positioning data with the use of GPS technology, and then they send data to the end user through traditional cellular phone networks.

But what about areas with no cell phone coverage? Perhaps one best asset of GPS real time tracking is that it can operate everywhere. It works even in oceans and deserts, but the cell phone modem has to be replaced by a satellite modem. This way, the position information can be sent over a communication satellite network. However, there is still a disadvantage to that since the satellite GPS real time tracking devices are more sophisticated and bigger than the devices with a cell phone modem. And, these devices as well as the services are much more expensive.

The most common use of GPS real time tracking devices is in cars. The systems usually transmit the location positions along with other additional information, such as speed and direction of the vehicle, and this information is transmitted directly to the user.

There is actually a lot of different GPS real time tracking systems available for cars and vehicles. The availability, however, depends on the country, the GPS provider, and other factors. Also, the GPS location data of the unit can be transmitted via mobile or cell phone systems, radio communication and satellite systems as well.

The GPS real time tracking systems are composed of three main parts: The Mobile GPS unit; communication networks; and geographic maps. With these components, the systems are easy to install. The GPS receiver and cellular modem will just be fastened to the target. Then, a GPS antenna attaches with a magnet to the underside of the bumper cover and a miniature magnet mount cellular antenna fastens to the frame. The power is supplied by a direct connection to a vehicle power or by a field replaceable battery pack. The car monitoring system can then be accessed from a personal computer at your own home or office using a GPS real time tracking software. With the software, the location of the vehicle will be shown on a digital map of your area showing movement as it occurs.

There are many useful applications for real time tracking GPS systems and they are coming into use more and more everyday. Soon it will become a technology that we just take for granted, especially when it comes to our automobiles.
