摘　　要：针对室内外交互区域卫星定位系统和室内定位系统无法完成定位的现象,提出一种基于北斗和CSS信号的融合定位算法。该算法通过引入卫星钟差、电离层和对流层参数修正模型以及针对CSS室内定位系统提出一种距离误差修正模型,可以较准确地得到定位端到基站与卫星之间的距离,进而通过融合卫星伪距方程和基站伪距方程实现对室内外交互区域的定位。最后通过仿真实验验证了该融合算法的有效性。Considering Satellite Positioning Systems and Indoor Positioning Systems can＇ t realize po- sitioning in the indoor and outdoor interactive areas, this paper puts forward a fusion algorithm based on Compass and CSS signal. Satellite Clock Error, ionosphere and troposphere models are intro- duced for measuring precise distances between Location and Satellites or Base Stations, and an error correcting model for CSS Indoor Positioning System is put forward. And then the satellite and the base stations pseudo distance equations are fused to achieve localization in indoor and outdoor inter- active areas. Finally, the algorithm＇s effectiveness is proved though simulations.
