为了减小测角误差对导线点位误差的影响,提高井下控制网的精度,运用GAT陀螺全站仪进行井上、井下陀螺定向观测和平差处理,实现了井下导线的精确定位。通过实例分析,GAT陀螺全站仪在井下导线测量中极大地提高了导线的精度和可靠性。
We use GAT total station gyroscope in the inoue and underground.According to the observations and adjustment,the accurate positioning of underground traverse survey.The results show that GAT total station gyroscope greatly improves the accuracy and reliability of long-distance underground traverse survey.
