Global Positioning System (GPS)

The Global Positioning System (GPS) is a network of 24 satellites in high geosynchronous orbit above the Earth. Only 12 of these satellites are above the horizon at a given time. Vehicles with Audi Navigation systems are equipped with an antenna capable of receiving these GPS signals, and converting them to precise latitude, longitude and altitude coordinates. These data are combined with vehicle speed and direction information in order to provide route guidance.
