An integrated solution based on wide-beam SSA and SMA link support of TDRS is proposed to meet the requirements of safe operation and emergency management of manned space station. By adopt that wide-beam antenna, the chain building is simple, the requirement on the support conditions such as the attitude of the spacecraft is simple, and the reliable TT&C can be realized under the condition that the chain of the narrow-beam relay antenna of the platform cannot be built. During long-term operation, the relay satellite resources are released, and the relay satellite SMA active phased array link is used to continuously monitor the key telemetry and fault detection results of the platform in real time. Compared with the mode of centralized short-term downlink telemetry and interpretation according to the TT&C plan adopted by the traditional long management, the response to sudden faults of the platform is more timely and faster. At the same time, it supports astronauts to call the ground actively, and solves the problem of insufficient emergency communication capability of astronauts caused by the traditional mode of entering and leaving the station as planned.
