摘要 针对“北斗二代”卫星导航系统,首先,设计适合我国区域导航定位需求的GEO+MEO的星座;在此基础上增加一个倾斜地球同步轨道卫星星座扩充成一个GEO+MEO+IGSO的全球卫星导航系统;进行GDOP值和可见星数仿真,根据仿真结果对星座参数进行优化。 Aiming at the Beidou Ⅱ navigation and positioning system, a regional navigation system was designed to meet our country's request firstly. Then, it was expansioned to the global navigation system on this basis, using the constellation which had been designed to simulate the GDOP and the number of visible satellites. According to the simulation results, the parameters of the constellation were optimized.
