摘　　要：针对伪卫星独立组网,从精度因子入手,分析了对不同用户的定位精度。着重对空中用户的定位问题进行一系列的分析,并进行了仿真。对仿真过程中遇到的精度衰减因子(DOP)值分布奇异条带、定位精度较低等情况,研究了不同的伪卫星布局和增加卫星数目等解决方案。The emphasis in this work introduces the Plans of PL-only positioning system and analyzes the positioning accuracy on different users through the medium of Dilution of precision. According to a series of research on the problems about air user with emphasis, it has made some analysis and simulations on this project. In the course of simulation, there are some problems, such as singular swath of the distribution of Dilution of precision, the lower accuracy and so on. In this work, the different distribution of PL and the increasment of the PL number are used to solve the problems.
