| 摘 要： | 通过STK软件包对＂天链一号＂（TL1）卫星及4颗中地球轨道（MEO）卫星的轨道进行了仿真模拟,进而对TL1卫星对MEO卫星的覆盖情况进行了仿真。仿真结果表明：TL1卫星对4颗MEO卫星没法实现全天区覆盖。盲区出现在南、北美洲以西的东太平洋上空,经度范围-81°～-125°,纬度范围-22～22°.在制定相关的中继方案时,需要避免,当MEO飞经上述区域时,开展TL1卫星对MEO卫星的数据传输或信息交换。

| Abstract: | STK software package is used to simulate the orbits of TL1 and four MEO satellites.The coverage of MEO satellites by satellite TL1 is finally simulated.Simulations have indicated that coverage of 4 MEO satellites by TL1 is not seamless.There is a dead zone,spanning longitudes from 81 deg to 125 deg,and latitudes from-22 deg to 22 deg.It is suggested that data relaying and information exchange are forbidden during MEO satellites' crossing the dead zone for TL1. |
