If the connection between the GPS receiver and the satellites is compromised in any way, then real-time position information will be lost. The signals may be compromised due to: the surrounding landscape, valleys, hills etc., tunnels, buildings. To counteract these problems, vehicle navigation systems use an additional method called composite navigation to supplement the GPS information. This uses information from additional sensors in order to establish the distance moved and direction of movement of the vehicle. From this information the current position can be predicted (although with less accuracy than with GPS information). As soon as the satellite signals are available again, the system can update the driver with accurate position information. Using this technique, the GPS and composite methods work in a complementary way to overcome poor GPS reception and to ensure that the composite, calculated position information is accurate. In combination the systems provide an accurate basis for vehicle navigation 改革创新示范教材 * The Navigation system 任务 实施 改革创新示范教材 * The Navigation system 任务 实施 The system employs such main components as navigation control unit, turn angle sensor, wheel speed sensors, reversing signal and GPS antenna. During operation of the system the process includes three aspects: position finding, route calculation, navigation.
