摘要：A rotation determiner (23) determines whether the azimuth (AZ) angle of anantenna (3) rotates beyond a rotation range within a predetermined duration of time onthe basis of a predicted orbit value. When the AZ angle of the antenna (3) is determinedto rotate beyond the rotation range, an orbit determiner (24) determines whether anestimated satellite position is within a drivable range in which the AZ angle rotates from areference value beyond the rotation range, and in which an xEL axis can be driven in astate in which the AZ angle is set to a predetermined value that is permissible for the AZangle. When the AZ angle rotates beyond the rotation range and while the estimatedsatellite position is within the drivable range, a determiner (22) sends a command to aswitching section (17) to cause three-axis control, and a command to cause an AZcommand operator (15) to output a command value that keeps the AZ angle at apredetermined value. When the AZ angle rotates beyond the rotation range and whilethe estimated satellite position is not within the drivable range, or when the AZ angledoes not rotate beyond the rotation range, the determiner (22) sends a command to theswitching section (17) to cause two-axis control.
