PROBLEM TO BE SOLVED: To provide an antenna direction controller for an artificial satellite, capable of correcting the error of a present time to be calculated by a mounted computer by using a GPSR time, and reducing a ground side load, and increasing the estimating precision of the time error. SOLUTION: In this antenna direction controller for an artificial satellite, a time error estimator for inputting a present time to be calculated by a mounted computer and a time obtained by a GPSR, and for estimating and correcting the error of the time of the mounted computer on an orbit is added. |
