摘　　要：陕西北斗连续运行参考站(SHX-BDCORS)系统自2018年开通,已连续运行多年,通过设计多种控制点测量和连续测量方案对比分析,综合评估系统高精度定位性能,结果表明:陕西北斗CORS系统具有较高的稳定性、可靠性、易用性,定位精度符合设计要求,同时系统单北斗三号(BDS-3)定位结果精度在水平方向与全星座相当,在高程方向的精度略低,但较单北斗二号(BDS-2)在高程方向精度提升30%~40%。The continuously operating reference stations(CORS)system in,Shaanxi BeiDou was opened in 2018 and has been running continuously for many years.By comparing and analyzing various control points measurement and continuous measurement schemes,and comprehensively evaluating the high-precision positioning performance of the system,the results showed that the CORS system in BeiDou,Shaanxi has high ease of use,stability,and high precision,and the positioning accuracy meets the design requirements.At the same time,the accuracy of the single BeiDou navigation satellite system(BDS)-3 positioning result of the system was comparable to that of the whole constellation in the horizontal direction,and the accuracy in the elevation direction was slightly lower,but it is about 30~40%higher than that of the BDS-2 in the elevation direction.
