There are a number of tracking devices available in the market and depending on what one needs and requires, one should do some research work in order to know more about their additional features.

A real-time GPS tracking device for cars is a very simple, yet so effective. It contains a GPS or Global Positioning System transmitter and uses the satellites orbiting around the Earth to give them the correct information with regards to the location. The GPS unit translates this information and converts these into images that the occupant of the vehicle can understand.

The tracking device uses trilateration to determine its exact location. This process requires three different satellites that send their own exact location of the GPS unit, which in turns measures the distance between itself and a satellite. Once the distance from three different satellites has been measured, the GPS unit performs a series of calculation to know its exact location. Some GPS device uses cellular networks instead of satellites.

These tracking devices need clear skies to receive the information from satellites. Dead spots can also be encountered in cellular networks.
