  • Patent number: 5173708
    Abstract: An attitude control system for an antenna on a mobile body is comprised of a supporting device for supporting the antenna in such a manner that the antenna is rotatable and is movable in the vertical direction, a driving device for driving the antenna, an attitude change detecting device for detecting a speed of the attitude of the antenna relative to to the source of radio wave, a first control device for controlling the driving device in such a manner that the antenna is driven for cancelling the deviation between the resultant of the attitude change detecting device and a correcting value a receiving device for receiving radio wave which is connected to the antenna, a second control device for changing the attitude of the antenna toward higher receiving level derived from the receiving device and a drift correcting device for renewing the correcting value in such a manner that accumulated vector becomes zero which is the accumulation of a vector upon the changing of the attitude of the antenna.
