摘要： 文中分析了中国区域性覆盖卫星导航系统“北斗”系统的特点,提出了采用“北斗”系统静止轨道卫星结合若干倾斜圆轨中轨MEO卫星,构成中国区域性覆盖星座的设计思想。文章给出了卫星导航定位系统星座优化设计方法,比较了多种设计思想和多种轨道形式的设计方案。通过仿真计算分析,在多种设计结果中,得到了优选的2颗GEO卫星结合若干MEO卫星星座设计方案设计结论。并且针对所选星座的覆盖性能,仿真给出了区域性覆盖优选星座的PDOP特性。

Abstract: In this paper, the characteristics of “Beidou” satellite positioning system are analyzed. The idea of “Beidou” GEO satellites combined with some MEO satellites constellation to perfect Chinese regional satellite positioning system is put forward. The details of general satellite constellation opimization method are presented, and the comparison of different design ideas and different orbital constellation concepts is given. Through simulation and comparison, among those design schemes, 2 GEO plus some MEO satellites scheme is chosen to be the final optimized one. With respect to the chosen constellation cover performance, the PDOP characteristics are calculated.
