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2.51mm和0.75mm,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 test, this paper compares compass with GPS to understand the actual positioning preci- sion of compass. According to E class network test, the results show that the mean of plane positioning precision between compass and GPS are 2.51 mm and 0.75 mm respectively, and it is proved that the plane positioning preci- sions of compass and GPS are nearly on the same level, and meet the need of static positioning survey.
