摘　　要：静态GPS相对定位满足各等级平面控制测量要求已毋庸置疑,对于静态GPS高程究竟达到何种精度,许多测绘工作者众说纷纭。通过实验的方法对不同的GPS高程施测方案产生的不同结果进行分析,论述静态GPS高程的施测精度,以供测绘工作者参考。There is no denying that static GPS relative positioning meets the demands of each grade plane control survey,but static GPS height on earth reach which precision,many survey workers have different opinions.This paper makes analysis of different results which different GPS height survey project producted by experimental methods,in order to state static GPS height precision,which supplies the reference for survey workers.
