摘要
分析了地下导线加测陀螺定向边后的平差方法和精度 ,对比了陀螺定向边作为坚强边和非坚强边时的平差结果 ,证明两者没有本质的区别 ,因此在平差计算时 ,不需对陀螺边进行判断 ,一律作为坚强边对待 。
The adjustment methods and accuracy of underground traverse are analyzed after gyro orientation line is observed. The adjustment results are compared when the gyro orientation line is chosen as steady line and non steady one,and proved that there is no essential difference between these two results. Therefore,it needn't to justify the gyro lines when the adjustment calculation is operated,and they can be altogether treated as steady ones. In this way,the calculation work is largely simplified.
