摘要
首先给出了基于遗传算法进行OTE场地伪卫星布站优化的设计思想和设计方案。然后在6种环境下进行了OTE伪卫星布站优化方案的仿真分析。通过对优化后6种环境下近20种方案的分析,得出几点结论:伪卫星布站优化应考虑多平面多用户的综合适应度;伪卫星的平面位置分布应尽可能布满整个服务区域;同时考虑伪卫星定位系统平面和高程定位精度时,伪卫星的空间位置应尽可能分布在多平面内。
Firstly, the detailed design idea and scheme based on genetic algorithm were put forward. Then the simulation analysis of pseudolites station determination of Galileo OTE under 6 different surroundings were given. From almost 20 schemes under 6 different surroundings, it was shown, by comparison and analysis, that the integrated adaptabilities of multi-users should be considered. The pseudolites level stations should be distributed in the whole servings area. When the level and vertical precision being considered together, the pseudolites spatial stations should be distributed in multiple planes.
