適用于我國的中軌TDRSS星座方案研究
The Satellite Constellation Scheme Study for MEO-TDRSS of China

摘要: 基于中軌跟蹤與數據中繼衛(wèi)星系統(tǒng)(MEO-TDRSS)星座方案的功能和業(yè)務特性，對4種常見星座實現的我國中軌TDRSS的覆蓋特性和星際鏈路性能進行了仿真分析和比較。仿真結果表明，我國的中軌TDRSS宜采用具備衛(wèi)星全球均勻分布特性的玫瑰星座和共地面軌跡星座。Abstract: 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.
