构网要素对CPⅢ轨道控制网精度影响仿真分析

Simulation analysis on the CPⅢ orbit control network accuracy influences of the compose network elements

文中针对CPⅢ轨道控制网的布网形式,以采用边角后方交会所形成的网形为分析对象,针对由不同自由测站点位置对CPⅢ控制点间形成的距离和角度误差进行了仿真分析。探讨了CPⅢ点在不同先验精度下的点位精度,分析了距离和角度误差产生的规律和主要影响因素。

For the net form of CPⅢ orbit control network, by using the mesh formed the side -angle resection as the analysis object, simulation analysis of was carried out the distance and angle error between CP Ⅲ control points formed by different free station location. CPⅢ positional accuracies under the different prior precision were discussed, and the law and the main influence factors were analyzed formed by the distance and the angle error.
