However, they all work on appropriate similar principles.

GPS systems use satellites that orbit the earth in order to send signals that are received by the GPS gadget. The system has software that interprets the signal and uses that data in pattern to form conclusions about the current location based on the time it took to receive the signal from the satellite, and the uttered location of the satellite that sent the data. By combining that information a conclusion can be drawn by the GPS or auto navigation system as to the exact position of the GPS device.
