Abstract
An axial-discrepancy amount calculating section calculates discrepancy amounts between an azimuth angle and an elevation angle of a satellite in the mobile object-fixed coordinate system computed by a satellite direction computing section and an azimuth angle and an elevation angle of an antenna in the gimbal coordinate system detected after the antenna is directed by a peak direction drive controlling section to a direction in which a peak received signal is given, and then commands an axial-discrepancy amount correcting section to change the axial discrepancy amount.
