PROBLEM TO BE SOLVED: To provide an antenna attitude control system in which a position measurement error by the GPS is eliminated so as to direct an FPU paraboloidal antenna toward a relay vehicle accurately. SOLUTION: An FPU reception base station 3 measures its own position by a GPS device 9 to obtain a GPS position measurement error based on a difference between the position measurement information and absolute position information of the GPS antenna having been measured in advance accurately. Since the position measurement information from a relay vehicle 2 includes a similar GPS position measurement error, the error is corrected by a data processing section 7 and the attitude of the FPU paraboloidal antenna 4 is controlled based on the corrected position measurement information. |
