Navigation Systems

Satellite navigation systems allow small electronic devices to determine their location (Longitude, Latitude, and Altitude) in within a few meters using timesignals transmitted along a line of sight by radio from satellites. Automotive navigation systems use GPS (global positioning system) technology to identify the location of a vehicle. GPS satellite technology works by measuring how long it takes a radio signal from a satellite to reach a vehicle, and then calculating distance using that time.

  How it works

Navigation systems compare GPS signals with maps that are stored either on a DVD or on a device’s hard drive to produce a visual map of the vehicle’s route and current location. On GM vehicles, the map appears on an LCD that is installed within the vehicle’s dashboard.
