| 摘 要： | 为满足卫星导航系统由于某种原因暂时不能使用时的导航定位需求,本文利用伪卫星在大量仿真计算的基础上,针对空中及地面用户,设计了4星、5星、9星独立组网的布局方案。分析了其定位精度的分布情况以及随用户位置的变化规律。并将设计结果应用于局部地区,为实际应用提供了参考依据。

| Abstract: | In order to meet the navigation need when satellite navigation system is out of use because of some reason,regarding the air-based and the ground-based users,the four satellites,five satellites and nine satellites pseudolite-only configurations are given through large amount of simulations.The distribution of precision and the changing rules are analyzed.The design results are used in the local area which can provide some useful references for practice. |
