Navigation apparatus

摘要

In a navigation apparatus of hybrid navigation type, navigational parameters for a moving body such as a vehicle are detected by a self-contained sensors, such as acceleration sensor, angular velocity sensor and distance sensor, without relying on any informational support from the outside, and positioning data transmitted from a plurality of artificial satellites are received at a position of the moving body by a GPS unit and outputted therefrom. The position calculation based on GPS data takes a relatively long time compared to the self-contained navigational data. Instead of performing calculations to allow for this delay by calculation, the output data of the self-contained sensors at the same positioning time as the GPS data are used to calculate navigational data.
