PROBLEM TO BE SOLVED: To provide the reference information of satellite attitude control from an installation type reference transmitter by measuring a difference between the predicting gain and the measured gain of the receiving of signal, which is based on the predetermined recognition of space change of the gain of a satellite antenna, so as to lead the correcting signal for showing the attitude error of a satellite. SOLUTION: Signal from a reference transmitter 10 is sent to a sub beam 4, and received by receiver antenna 30 of a satellite 1, and while relayed to a ground station 8 by a satellite antenna 32 so as to measure the attitude correcting signal. This attitude correcting signal is received by the ground station 8 so as to measure the gain, and this measured gain is compared with a predicting gain of the receiving of signal based on the predetermined recognition of a space change of the gain of the satellite antenna 32, and a difference of the comparison is measured so as to lead the correcting signal for showing the attitude error of the satellite 1. The reference information of the satellite attitude control can be thereby obtained from an installation type reference transmitter 10. |
