Abstract: A rotation determiner determines whether an antenna azimuth (AZ) angle rotates beyond a rotation range within a predetermined time based on a predicted orbit value. When the antenna AZ angle rotates beyond the rotation range, an orbit determiner determines whether an estimated satellite position is within a drivable range that the AZ angle rotates from a reference value beyond the rotation range. When the AZ angle rotates beyond the rotation range and the estimated satellite position is within the drivable range, three-axis control is executed, and the AZ angle is kept at a predetermined value. When the AZ angle rotates beyond the rotation range and the estimated satellite position is not within the drivable range, or when the AZ angle does not rotate beyond the rotation range, two-axis control is executed.
