Filed: 1983-11-08
Abstract: PURPOSE:To evade radio wave interference automatically by transmitting a pilot signal which controls the down-circuit transmission power of a satellite station as an obstacle or the transmit power of the up-circuit of the ground station to a relative satellite station. CONSTITUTION:Satellite circuits put in operation at the same or close frequency, e.g. system A between a ground system 1 and a satellite station 2 and system B between a ground station 3 and a satellite station 4 are put in operation through up-and down-circuits 5 and 6, and 7 and 8. Then, the up-circuit 7 of the system A and the down-circuit 8 disturb the satellite 2 and ground station 1 of the system A as disturbing waves 10 and 9 respectively. In this state, when the ground station 1 tracks the satellite station 2 with a pilot signal 11 of the same frequency as the reception frequency of a pilot receiver for radio wave interference detection that the satellite station 4 has, the satellite station 4 also detects the pilot signal through a path 12. The outputs of the up and down circuits of the satellite station 4 and ground station 3 are controlled according to the detected intensity. When the system A disturbs the system B, similar constitution is set up to remove mutual radio interference easily.
