摘　　要：With the increasing number of satellites being launched in China,the demand for Telemetry,Tracking,and Command(TT&C)resources is also increasing.Because of the global coverage and resource requirements of TT&C management,this paper proposes a TT&C scheme based on the Global Short-Message Communication System(GSMCS)of the BeiDou-3 Navigation Satellite System(BDS-3).The system composition,workflow,and functions of satellite TT&C are analyzed using the GSMCS of BDS-3.Through the coverage analysis of the Medium Earth Orbit(MEO)constellation of BDS-3,scheme’s applicability is pointed out,and the correctness of the analysis results is verified via simulation.The value range of the link distance is derived by calculating the range of the distance variation between any 2 satellites in the BDS-3 MEO constellation and combining the intersatellite routing scheme.The calculation results show that the response time range of the autonomous request management application of in-orbit satellites based on the GSMCS of BDS-3 is 1.407 to 2.448 s.This can meet the requirements of TT&C service.
