Global short message communication(GSMC) service provided by BeiDou Navigation Satellite System (BeiDou system, BDS) can be utilized by low earth orbit(LEO) earth observation satellites to achieve telemetry, tracking and control(TT&C) and information distribution throughout the day. The system architecture of TT&C applications for LEO satellites based on BDS GSMC service is proposed and service flow is given in this paper. A simulation scenario was established, and several service capabilities index including cover-age characteristics, data transmission path, data transmission delay, and reliability are simulated and analyzed. Results have shown that the GSMC service provides more than 75% of orbit coverage for LEO satellite users whose orbit attitude varies from 500 – 2000 km, while some users can achieve 100% cover-age. The maximum coverage block time interval does not exceed 25 min, and the data transmission delay of single frame is less than 108 s, with certain redundant transmission capability achieved. The service can effectively support the telemetry and telecommand and data distribution applications of LEO satellites abroad and can be used as a supplementary method in satellite TT&C systems.
