GPS控制网公共点兼容性问题研究

Research on common point compatibility of GPS control net

介绍了GPS控制网公共点兼容性对平差结果精度的影响及对公共点兼容性进行检验的必要性,分析了对公共点兼容性进行检验的主要检验量及其相互关系,并比较几种常用公共点兼容性检验方法的优缺点,最后结合某次测量工作对公共点兼容性检验的方法和检验结果进行比较。

This paper first introduces the affect of the incompatibility of common point in GPS control net on adjustment result,and the necessity of checking the compatibility.next it analyses the primary criteria of checking the compatibility of common point,and the interre-lation of these critera comparisons of the advantages and disadvantages among some methods of checking the compatibility of common point are described in this paper.Some summariza-tions combined with a surveying project are presented,finally.
