ABSTRACT:
A navigation apparatus for detecting and displaying at least an azimuth of a movable body, includes: an angular speed sensor for detecting an angular speed accompanied by the change in the azimuth of the movable body, and outputting angular speed data, which indicates the detected angular speed with respect to an output fiducial value; an azimuth detection device for detecting the azimuth of the movable body, and outputting azimuth data; and an offset correction device for computing a first amount in angle change of the azimuth of the movable body within a predetermined time interval from the angular speed data outputted by the angular speed sensor, computing a second amount in angle change of the azimuth of the movable body within the predetermined time interval from the azimuth data outputted by the azimuth detection device, and correcting the output fiducial value of the angular speed sensor so that the first and second amounts in angle changes become equal to each other.
