全球限时重访星座构型设计

Global Limited Time Revisit Constellation Design

针对全球范围内任意地点的限时快速重访星座设计问题,进行了重点研究。对不同轨道类型卫星的对地覆盖特性进行了分析,重点针对星座重访时间问题进行了研究。基于赤道的打靶法星座设计方法,设计了可在全球范围内可实现任意地点限时重访的星座构型设计方法,并且得出了全球范围2小时重访的星座设计构型,并对以上结果进行了仿真验证。实验结果表明,提出的星座构型设计具有正确性以及使星座使用的卫星数量达到最低。

This paper focuses on the problem of time-limited fast revisiting constellation design at any location in the world,and analyzes the ground coverage characteristics of satellites with different orbital types.The issue of constellation revisiting time was studied based on the equator's shooting method for constellation design.A constellation design method that can be revisited at any location was designed,and the constellation configuration of two-hour revisited configuration was obtained.The experimental results show that the proposed constellation configuration is correct and the number of satellites used by the constellation is the lowest.
