边角网测距精度的验后计算

Estimation of Distance Measuring for Network with Side and Angle Observation

边角网方差分量估计得到的测边方差分量并不具体表示测距的精度。要求得测距精度的验后估值,必须根据方差分量估计过程中的有关数据,应用间接平差原理来计算,本文还通过一个实测例子给出了计算的方法和步骤。

The accuracy of distance measuring in the network with side and angle observation should be calculated with the related data in the estimation of variance. components.
