GPS car tracking has become very popular with the increase of the need for car security. In the attempt to limit criminality, the police as well as the government often use GPS car tracking, although, there are also private users, civilians that rely on such technology. The device is a small unit that when attached to a vehicle or a person provides precise information on the position of the asset. A GPS car tracking unit could also record the data or simply transmit it to a computer, a cellular or some other form of central database. The transmission of the signal is not possible unless the GPS car tracking device has an incorporated modem in its structure.

Then, the GPS car tracking system displays the data on a map monitor. The tracking device also contains a memory card. Although the GPS car tracking system is popular for preventing car theft or for different criminal investigations, a GPS device is suitable when hiking or jogging too. Sometimes, one can also collect data to create a map with the help of a GIS software, particularly since a GPS receiver has geo-catching features incorporated as well.

Mobile phone GPS tracking or GPS car tracking can apply to very more complex investigations from the business environment. The vehicles of commercial fleets always have GPS car tracking units incorporated. The data provided by the GPS car tracking system can also be displayed in the form of reports, a system that is widely used both in Europe and in North America.

Delivery and taxi vehicles, luxury automobiles and armored trucks are equipped with GPS car tracking units so that the location of the vehicle can be constantly monitored. With more special units, one can activate the tracker via a SMS but only in theft cases. The device is thus incredibly efficient for the authorities that deal with lost or stolen vehicles cases. Very often GPS car tracking systems are installed on race cars particularly in the case of long circuits in areas that are more difficult to access.
