GPS/BDS精密单点定位解算精度对比分析

Comparative analysis of point positioning solution accuracy of GPS and BDS

为明确北斗导航定位系统在高原地区的精密单点定位精度,以GPS定位成果为参考对其进行精度评价与分析。结果表明:北斗导航定位系统的静态精密单点成果在高原地区可达到厘米级,对青海省大部分无基准网、无网络信号地区的基础测绘工作具有一定的参考价值。

In order to understand the precise single point positioning accuracy of Beidou navigation and positioning system in highland area, the accuracy evaluation and analysis were carried out with GPS positioning results as reference. The results show that the static single-point precision of Beidou navigation and positioning system can reach the centimeter level in the plateau area, which has certain reference value for the basic surveying and mapping work in most of Qinghai without referring network and no network information area.
