摘要
文中以北半球高纬度地区MGEX跟踪站数据为基础,对比分析了GNSS多系统伪距单点定位精度。试验结果表明,高纬度地区BDS-2/BDS-3、BDS-3、GPS各频率水平精度优于1 m,高程精度优于1.6m,Galileo、GLONASS各频率定位精度较差,水平精度优于2 m,高程精度优于3 m,BDS-2相比其他系统定位精度最低。
Based on the data from MGEX tracking stations in high latitude areas of the Northern Hemisphere, the GNSS multi-system pseudorange single-point positioning accuracy was compared and analyzed. Test results showed that the horizontal accuracy of each frequency of BDS-2/BDS-3, BDS-3, GPS was better than 1 m in high latitude areas, and the height accuracy was better than 1.6 m, while the positioning accuracy of Galileo and GLONASS frequencies was poor, and the horizontal accuracy was better than 2 m, the elevation accuracy was better than 3 m, BDS-2 had the lowest positioning accuracy compared with other systems.
