Abstract
A hybrid navigation system for determining a relative position and direction of a vehicle and method therefor. In the hybrid navigation system and method, a magnitization quantity on a vehicle body which affects an output detection result of a geomagnetic sensor is calculated on the basis of a forwarding direction data derived from such as a GPS (Global Positioning System) absolute position calculating circuitry. Furthermore, in order to prevent an erroneous determination of the relative position and direction of the vehicle, the calculation on the relative position and direction of the vehicle on the basis of the detection result of the geomagnetic sensor is halted when the vehicle does not run on a straight road.
