摘　　要：基于BDS/GPS CORS试验系统,利用伪距信息,通过多基站差分定位技术,对BDS/GPS融合差分网定位进行研究。结果表明,多基准站BDS/GPS融合差分网单历元实时定位精度优于1 m,40历元实时滑动平均定位精度0.5 m左右,大大提高了常规伪距定位精度,能满足大多数用户的导航定位需求（精度0.1~10 m）。Performance of positioning with differential network of BDS/GPS fusion system was analyzed using pseudo-range information through multiple reference stations differential positioning technology,based on BDS/GPS CORS test system. The experiment results indicate that positioning accuracy with multiple reference station BDS/ GPS fusion system of single epoch real-time is not larger than 1 m,40 epoch real-time moving average positioning accuracy is about 0.5 m, pseudo-range positioning accuracy is improved greatly. The method can meet demand of users for navigation and positioning.
