Purpose, Function
The GPS antenna receives signals sent from GPS satellites and sends them to the car navigation unit.
NOTE:
GPS (Global Positioning System) was developed by the Pentagon (U.S.A.) as an object locating system using satellites. The GPS antenna receives signals from several of the satellites orbiting at an altitude of approx. 21,000 km {13,049 mile} to detect the current position of the vehicle.
Construction
The GPS antenna is installed inside the center part of the instrument panel.
