摘要
本文针对天津市北斗地基增强系统进行了性能测试。测试内容包括时间可用性、空间可用性、静态定位精度、RTK定位精度。测试结果表明,天津市北斗地基增强系统满足全天候95%覆盖全天津市域的毫米级事后静态定位和厘米级RTK定位精度要求,GPS+BDS组合较单GPS、单BDS在静态或动态RTK定位具有更高精度和可靠性。
In this paper,the performance test of Tianjin Bei Dou ground-based augmentation system is carried out. Test contents include： time availability,spatial availability,static positioning accuracy,RTK positioning accuracy. The results show that the Tianjin Bei Dou ground-based augmentation system meets requirements of millimetre order for static positioning and centimeter order for RTK Positioning in all-day and 95% coverage of Tianjin area. Compared with single GPS and single BDS,the combination of GPS ＋BDS in static or dynamic RTK positioning has higher precision and reliability.
