SATELLITE COMMUNICATION SYSTEM, STATIONARY SATELLITE, GROUND STATION, AND SATELLITE COMMUNICATION METHOD

PROBLEM TO BE SOLVED: To provide a satellite communication system which constitutes duplex communication network by stationary satellites. SOLUTION: The satellite communication system has six stationary satellites S1 to S6 and two or more ground stations 1 and 2, and each stationary is capable of communicating with other stationary satellites, wherein the six stationary satellites are divided into an odd-numbered group (S1, S3, and S6), an even-numbered group (S2, S4, and S6) and adjacent stationary satellites belong to the different groups, and stationary satellites in each group communicate with one another, thereby constituting the communication networks which are duplexed by the two groups.
