している。In the conventional geostationary satellite control system described above, however, a dedicated ground control antenna facility is required for each geostationary satellite, so that the geostationary positions of two adjacent geostationary satellites A and B are different from each other. Even if they are approaching, it is necessary to construct a ground control antenna facility each time they launch a geostationary satellite and attempt to operate after geostationary operation.When planning a service using a geostationary satellite, the satellite body and its launch cost are required. Along with this, a large amount of construction cost for ground control antenna equipment is required.

管制方式。1. A main receiver that receives a satellite control command from a ground control antenna facility, and a main transmitter that transmits satellite control information of the satellite to the ground control antenna facility until the satellite is launched and remains stationary. In a geostationary satellite control system equipped with an omni-antenna used, a high-gain antenna used after stationary, and a redundant receiver and transmitter, two adjacent geostationary satellites that are both stationary Among the above, the satellite control command received by the main system receiver of one geostationary satellite equipped with the main system transmitter for transmitting satellite control information to the ground control antenna facility is transmitted from the main system transmitter of the geostationary satellite to the omnidirectional transmitter. While transmitting to the other geostationary satellite via the antenna, the satellite control information from the other geostationary satellite is received by the redundant system receiver via the omni-antenna and then transmitted to the redundant system. More to the ground control antenna equipment via the high-gain antenna, the other geostationary satellite is transmitted by the main or redundant receiver via the omni antenna of the transmitting satellite control command from the one geostationary satellite. While receiving, the satellite control information of its own is transmitted from the main or redundant transmitter to the one geostationary satellite via the omni-antenna.

When one of the main system transmitter and receiver of the one geostationary satellite and the redundant system transmitter and receiver of the one geostationary satellite fails, the terrestrial control antenna equipment is connected to the other geostationary satellite. Directly using the high gain antenna of the other geostationary satellite to switch to transmit and receive control commands and satellite control information, and use the omni antenna of the other geostationary satellite to communicate with the one geostationary satellite. 2. The geostationary satellite control system according to claim 1, wherein communication is performed by using the above method.
