摘要
研究了需要对地面目标进行连续覆盖的星座的设计问题。首先推导了对覆盖性能有重要影响的星间覆盖间隔时间和轨道面覆盖间隔时间的计算公式,通过算例针对不同配置的星座进行了计算,使用工程仿真软件STK验证了分析结果。通过理论分析、算例计算以及工程仿真为该类型星座设计提供了理论指导。
In this paper, design of constellation in need of continuous coverage for ground target is studied. The equations of two variables, gap time of satellite coverage and gap time of plane coverage, which having essential influence on the coverage capability are inferred. They are calculated in the case of constellations with various deployments. Finally, the inferences are validated using the engineer simulation software STK. This paper provides theoretical guidance for constellation design through theoretical analysis, calculated examples as well as engineering simulation.
