本文概述了跟踪与数据中继卫星系统的定义与优越性,分析了影响我国数据中继卫星网星座构形的主要因素,提出利用卫星工具包(STK)软件实现仿真分析数据中继卫星网星座构形的方法与步骤,并设计了高、中、低三种轨道中继卫星与用户卫星之间的可见性分析仿真实验,最后,初步分析了仿真实验获得的数据,并根据仿真结果提出了我国跟踪与数据中继卫星系统星座构形的初步设想。

This paper summarized the definition and advantage of the Tracking and Data Relay Satellite System-TDRSS. Then it analyzed the main factors that influenced the construction of our TDRS constellation. We put forward the method and steps to realize simulation and analysis of the construction of TDRS constellation by using the Satellite Tool Kit (STK) software. Further more, we have also designed a simulating experiment to analyze and compute the accesses between the data relay satellites and the user satellites which are at GEO, MEO and LEO respectively. In the end, the data acquired from the simulating experiment are primarily analyzed. And by the simulating result we bring forward a primary vision for the construction of Chinese TDRSS constellation.
