PURPOSE:To decrease the amount of calculation by forecasting the moving direction of a sattelite by extrapolation without deciding on a track element, etc. CONSTITUTION:The radio wave output of an antenna 1 for tracking is connected to a tracking receiver 2, whose output signal is supplied to a control circuit 4 for EL (elevation) control and a control circuit 5 for AZ (azimuth) control. Further, the EL angle and AZ angle of displacement of machine systems 10 and 11 are detected by angle detectors 12 and 13, whose detection outputs are supplied to a zenith tracking device 15. Its output is supplied as input control signals to said control circuits 4 and 5. |
