GPS网中已知点的可靠性检验

The Reliable Examination of Known Points in GPS Net

在GPS控制网中,已知点的误差大小将直接影响到GPS定位成果的精度,GPS网中已知点的可靠性检验是GPS测量数据处理中一项十分重要的问题。为了获取高质量的GPS定位成果,对GPS网中的已知点必须进行可靠性检验,以便发现并剔除含有粗差的已知点。本文提出了一种可靠性检验方法,即约束平差法。

In GPS network, the errors of known points will effect the accuracy of GPS positioning result. The reliable examination of known points is very important thing in GPS data processing. In order to acquire result of height quality, we must exam the reliability of known points, so that we can find out gross error and delete it. In this paper, I give a cut - way to exam these known points. This matter is called restrain adjust in surveying.
