A GPS tracking system is a device that takes the help of the Global positioning system for determining the precise location of a person or a vehicle and records their position at regular intervals. The recorded location is either stored in the tracking unit or transmitted to an Internet connected computer or a central location database. This is possible with the help of satellite, radio or cellular modem that is embedded in the unit.

GPS Tracking Systems are not new. For example, amateur radio has been operating their free GPS tracking system, Automatic Position Reporting system since 1982.

In US, police require a search warrant, if they wish to use GPS Tracking Systems. However, the private citizens can use it, as the fourth amendment does not limit the actions of private citizens. The GPS tracking devices raise issues about self-privacy.

The US military mostly uses the GPS tracking system. A series of satellites send signals to a GPS tracking system. It then calculates the position by latitude and longitude. Once the GPS gets familiar with its position, it helps users to determine directions and distances to other locations.

GPS tracking systems also help in outdoor activities such as camping and hiking. A GPS fish finder that uses both GPS tracking system and sonar finds fish in a pond. GPS enabled pet collars help to track pet dogs.

Another use of GPS tracking system is the child tracking system. A GPS tracking system with a receiver in a child's cell phone or wristwatch ensures their safety. Real time vehicle tracking system installed in a vehicle provides information about the location and speed of the car.
