摘要
星座稳定性设计是星座总体工程设计的主要内涵.针对北斗卫星导航系统(一期)星座稳定性设计问题,在利用解析方法深入分析星座摄动运动规律的基础上,综合考虑系统覆盖、导航精度、几何构型等约束条件,提出一种将发射部署、被动摄动、主动控制相结合的星座稳定性一体化设计方案.北斗星座系统的部署和运行结果表明:在时间和空间尺度上,星座动态几何因子(DOP值)稳定,重点服务区域动态DOP值小于4.2,在受限于构型维持控制的卫星可用性指标方面:IGSO卫星可用性大于99%,GEO卫星平均可用性大于96.7%.
The constellation stability design is the key consideration for satellite constellation engineering. An integrated design approach was reviewed for the constellation stability of compass（Beidou） regional navigation and positioning system（CRNPS） in this paper, the details were presented about the approach how to cater for the navigation precision, common view and geometry configuration requirements, as well as how to budget the constellation assignation and perturbation compensation. Real constellation flight orbital data of CRNPS was deployed to ascertain that： the constellation is dynamic stable in line with time and space dimension, the dilution of precision（DOP） is less than 4 within service region, and the satellite availability subject to configuration maintenance（SCM-SA） can achieve 99% and 97% for inclined and none-inclined constellation orbit.
