| 摘 要： | 以三类卫星轨道为例，利用STK分析软件就“天链一号01星”对三类轨道卫星的中继能力进行仿真，其中仿真参数包括一天内可中继次数、最短中继时间、最长中继时间、平均中继时间和可中继时间百分比等关键指标。仿真结果表明：“天链一号01星”对400～800km轨道高度的低轨道卫星的中继时间百分比可达55％以上；对20000-24000km中轨道卫星的中继时间百分比可达90％以上；对倾斜地球同步轨道卫星的中继时间百分比可达100％。

| Abstract: | Taking three types of orbits for examples,data relay capabilities for the first Sino-TDRS satellite are simulated and assessed via STK software.Such indexes are presented as daily relay frequency,shortest relaying interval,longest relaying interval,mean relaying interval and temporal percentage of availability of data relay.Simulations reveals that the first Sino-TDRS satellite can provide 55% relaying opportunity for low Earth orbiting satellites,and more than 90% for middle altitude satellites,and 100% fo... |
