多机动站交叉定位系统精度分析及优化OA北大核心CSTPCD

Considering the stations'motility feature of the motility multi-station cross location System,the factors which affecting loca-tion accuracy have been analyzed through the principle of the direction finding cross location technology.Taking four stations cross lo-cation system for instance,because of two typical applying scenes of the target distribution known and station unlimited,as well as random station layout while station moved,the optimizing station layout according to target distribution and optimizing data processing algorithm according to the fixed station layout have been advanced.The location accuracy and the location area have been optimized without adding extra station.The method is worth to popularizing because of low cost,low difficulty and fine location result.
