摘要
通过实际测试,将北斗和GPS进行对比,了解北斗静态定位的实际定位精度情况。按照E级网测试的结果表明,北斗和GPS定位的平面点位平均中误差分别为2.51 mm和0.75 mm,证明北斗系统和GPS的平面定位精度基本在同一量级上,能够满足静态定位测量的需要。
Through actual tests, this paper compares Compass with GPS to understand the actual positioning precision of Compass. According to E class network the test results show that the plane positioning mean RMSE of GPS and Compass are 2.51mm and 0. 75mm respectively, and it is proved that the plane positioning precision of Compass and GPS is on the same level basically, and the Compass can meet with the needs of static positioning survey.
