关于三边网与三角网精度匹配问题

Accuracy Matching for the Trilateration and Triangulation Network

本文根据四种典型网型的三角网和三边网的协因数阵,分析比较两类控制网的点位中误差、相邻点的点位中误差和横纵向中误差,在此基础上提出了测边与测角精度之间的匹配标准。

This paper, based on 4 typos of typical networks arid variance-covariance matrixes in trllateration and triangulation, analysed the mean square error of one point, the retative errors of adjacent points and the closing errors in departure and in latitude ones. Thus, the criterion of accuracy matching between both networks is presented.
