ABSTRACT:
A heading detecting apparatus for estimating a current heading of a moving body is described that individually analyzes and evaluates error factors that are respectively included in the heading data of a magnetic sensor and in the angular velocity data of a turning angular velocity sensor (e.g., optical fiber gyro, mechanical gyro, vibration gyro, gas rate gyro) and determines the rate of use of the output data of the turning angular velocity and magnetic sensors.
