Abstract

PURPOSE:To detect the absolute azimuth angle of an antenna and to control the directivity angle of the antenna by fitting an angle detector directly to an AZ or EL axis drive structure of the antenna. CONSTITUTION:The angle detector 8 detecting the absolute azimuth of the antenna is fitted directly to the AZ axis drive motor 3 being the AZ drive structure of the antenna. The detector 8 detects a deviation of the directive direction of the antenna OA from the north ON as an angle thetaG. In the case of directing the antenna in the direction OC, an angle thetaC desired to be directed is inputted directly to a controller 7 to direct the antenna in the direction OC. Thus, the directive angle of the antenna is controlled.
