Global Positioning System. It is a positioning and satellite navigation system that, through a dedicated network of artificial satellites in orbit, provides to a mobile terminal or GPS receiver information on its geographic coordinates and time and references of time (1pps) and frequency (10 MHz) anywhere on the ground or in the immediate vicinity where there is a contact free of obstacles with at least four satellites the system. The localization occurs through the transmission of a radio signal from each satellite and processing the signals received by the receiver.
