| 摘 要： | 当前临近空间技术是人们研究的热点,在临近空间建立伪卫星区域独立组网系统可以满足地面导航定位的需求。本文分析了卫星精度因子的计算方法,提出基于经验的伪卫星区域优化布局搜索算法,找到一种最优的临近空间伪卫星区域独立组网布局,利用MATLAB进行仿真。与其他几种相同高度的伪卫星布局做仿真比较,结果显示,本文提出的伪卫星布局的DOP值较小,并给出了一些重要的结论。

| Abstract: | In the contemporary day,near-space technology has already become a research focus.The establishment of the regional pseudolite independent network system in near-space can meet the needs of the navigation and positioning.An optimum distribution of the near-space pseudolite regional independent network system was found through analyzing the method of calculating the dilution of precision and raising empirical positioning algorithm of regional satellite optimum distribution in the paper.Finally,it simulated the configuration by MATLAB.Compared with the emulation of other several regional satellite distribution with the same height,a smaller DO Pof regional satellite distribution mentioned in the article was indicated and some crucial conclusions were given as well. |
