摘要

研究了使用中轨共地面轨迹星座实现区域覆盖卫星通信系统的优化方法

提出了一种能够完整描述该类型星座的编码标识方法

给出了多个适用于我国的星座方案实例。基于时变的业务分布密度特性对星座方案的参数进行了调整

使得星座的覆盖特性与业务分布密度更加一致。仿真结果表明该类型星座能够以较少数量的卫星为我国提供良好的覆盖性能。

Abstract

A design method for implementing regional coverage satellite communication system with medium earth orbit（MEO）common-track constellation（CTC）was studied.A coded notation which can describe CTC entirely was proposed and some optimal constellation schemes for China were presented.Moreover

the parameters of these constellations were adjusted again according to the time-varying traffic distribution density

which improved the consistency between the coverage performance of constellations and the traffic distribution density.The simulation results show that CTC can provide favorable coverage performance to China area with fewer satellites.
