ナ制御装置。 It receives a beacon signal from a ground station, which serves as a reference for antenna pointing control, reflected by a multi-beam antenna for both transmitting and receiving, and detects the reception level of this beacon signal and error components in the east-west direction and north-south direction.
Receives a reception level signal from a tracking receiver which is output as a reception level signal and a position error signal, respectively, compares this reception level signal with a predetermined appropriate range of the reception level signal, and determines whether the reception level signal is a predetermined reception level. A comparator circuit outputs an inhibit signal when the signal exceeds the appropriate range, and upon receiving the above inhibit signal, stops applying the drive signal to the drive mechanism attached to the multi-beam antenna, and returns the multi-beam antenna to a level where the received level signal is within the appropriate range. Equipped with a position hold device consisting of a switch circuit that fixes the beam at the position just before the beacon signal is crossed, and the action of this hold device minimizes the variation in the pointing position of the multi-beam antenna and maintains the communication line even when the beacon signal is lost. A multi-beam antenna control device characterized by:
