摘要
针对加测陀螺方位角后地下导线的平差及其精度分析问题,给出了严密的计算公式,并对陀螺方位角加测的最优位置进行了分析,得出了加测位置的最优解,加测一个陀螺方位角应位于导线的2/3处,加测多个陀螺方位角应均匀分布。
Countering the problem of underground traverse adjustment and the accuracy after measuring Gyro azimuth, a tight formula has been provided. And after analysing the optimal location after gyro azimuth measured, the optimal solution to measure the position has been obtained. A gyro azimuth measured should be located at 2/3 of the guide line, and many gyro azimuths should be uniform distribution.
