How Does The Gps tracking system work

A GPS receiver monitors microwave signals from the orbiting satellites. These signals contain the time of transmission and the position of the satellite. The receiver analyzes these signals by using the travel time of the signals and positions of the transmitting satellites to trilaterate its position. At least four signals are necessary for a good position lock using the GPS system.

After receiving these signals the Tracking device trasmint its location packet to Lebtrack servers over GPRS using the GSM network, our servers store these information in a database, and the online tracking application manipulates the data in user-friendly graphical interface such as tables and google map
