不同约束条件下GPS网平面约束平差的研究与分析

The Research and Analysis of the Constrained Adjustment of the Horizontal GPS Network Based on Different Conditions

本文主要论述了GPS网平面约束平差的方法及精度评定。最后,利用一个实例,根据其原理,采用不同方案在不同的约束条件下,得到的不同的约束平差的结果进行比较分析。最后得出当采用比较好的约束条件,相应地约束平差的结果精度比较高、可靠性好。

This paper mainly introduces the method of constrained adjustment of the horizontal GPS network and the analysis of accuracy. At last, on the base of its models, this paper applies an example and devises some plans to exam the correction of it, and analyses the advantage of it, as a result, acquires some helpful results.
