The Satellite Constellation Scheme Study for MEO-TDRSS of China

Based on the functionality and traffic characteristics of the Medium Earth Orbit Tracking and Data Relay Satellite System(MEO-TDRSS), the coverage properties and Inter-Satellite Link(ISL) performances of four familiar satellite constellation schemes which are adopted as the MEO-TDRSS of China are simulated and compared. The simulation results indicate that Rosette and Common-track constellations, whose satellites are distributed in the celestial sphere uniformly, are appropriate for MEO-TDRSS of China.
