基于误差椭圆的导线点坐标精度的分析

On analysis of traverse point coordinate based on error ellipse

利用间接平差的原理,对导线点的坐标进行了计算,并求出了各待定点的误差椭圆参数,依据误差椭圆参数,衡量了各待定点的综合精度情况,对于后续控制网的优化设计具有一定意义。

The paper indicates the principle for the indirect adjustment,calculates the coordinate of the traverse point,achieves the error ellipse parameter of all points,evaluates the comprehensive accuracy of all points by referring to the error ellipse parameter,so as to attach importance to the optimization of the following controlling network.
