GPS短边检定场的建立

The Testing Field of GPS Short Side Was Set Up

GPS技术日渐投入大地测量实际应用,本文详细介绍我国第一个GPS短边检定场的建立情况,介绍了使用T2000S电子经纬仪、ME—3000边频同测法及铟钢基线尺量边在短边高精度控制网测量中的特点及其能达到的精度;介绍了该检定场控制网的精度;并且就检定物中某些边长点位精度达到1mm左右是可信的;同时证明可以满足GPS检定的需要。

This paper introduced how to set up the first GPS testing field in our country, and reported the precision of Control network of GPS testing field.The results show that the precision of point position is about lmm.
