摘要

地球静止轨道（geostationary earth orbit，GEO）卫星轨道位置资源稀缺已久，巨型低轨卫星星座的发展浪潮使得低轨轨道资源也变得空前紧张，中地球轨道（medium earth orbit，MEO）星座作为GEO和低地球轨道（low earth orbit，LEO）星座的折中，必将成为各国博弈的角逐场，参考世界各MEO星座和我国国情，提出了一种（6+4）MEO星座方案，并使用STK（Satellite Tool Kit）软件对星座覆盖性能、星际链路特性和信关站选址及覆盖性能进行了仿真分析，该方案通过地面站中继实现轨道间通信，有效规避了利用星际链路实现轨际通信时存在的各种问题，使系统得到简化、可靠性得到提高，在全球低轨卫星轨道资源紧张的形势下具有很强的战略价值。

Abstract

Geostationary earth orbit (GEO) satellite orbit position resources have been scarce for a long time.The development of giant low-orbit satellite constellations has made the low-orbit resources unprecedentedly scarce.As a compromise between GEO and low earth orbit (LEO) constellations

the medium earth orbit (MEO) constellation will surely become a battle field for all countries.Referring to various MEO constellations in the world and our national conditions

a (6+4) MEO constellation was proposed.STK (Satellite Tool Kit) was used to simulate and analyze the constellation coverage performance

inter-satellite link characteristics

gateway site selection and coverage performance.Inter-orbit communication was realized through ground station relay

effectively avoiding various problems through inter-satellite links.The system was more simple and steady.It's much valuable in strategy in the circumstance of global low-orbit resources scarce.
