中国低轨移动卫星通信系统星座设计

本文研究低轨移动卫星通信系统设计中的一个基本问题－－星座设计问题，并给邮了我国低圆轨道移动卫星通信系统的星座设计方案，该星座是以三个轨道平面组成的２４颗星系统，它的高度为１３２６ｋｍ，轨道参数由本文提出的优化算法进行设计，本文用统计的方法对我国低轨系统方案和Ｇｌｏｂａｌｓｔａｒ系统（２４颗星方案）的覆盖性能进行分析比较，结果表明本文提出的系统对我国的覆盖特性优于Ｇｌｏｂａｌｓｔａｒ系统，本文还对圆

Constellation Design for a LEO Mobile Satellite Communication System of China

The constellation design for a low earth orbit (LEO) mobile satellite communication system (MSCS)is a basic problem in a non-geostationary satellite communication system.The coverage problem for China is considered emphatiacally.This paper proposes a constellation scheme of LEO and new optimun algorithms for orbital parameter selection to obtain maximum communication coverage rate.The statistical results have shown that the coverage rate for China using this constellation (24 satellites) is better than that of Globalstar system(24 satellites too).
