Improvement of Auto-orientation Surveying Calculation Program for Lower-locate Gyro Total Station and Its Accuracy Assessment

针对传统陀螺全站仪定向测量方法存在问题,依据陀螺全站仪测定井下坐标方位角的作业流程,制定其测定井下坐标方位角的计算程序,实现陀螺全站仪自动定向测量,并从一次测定的观测值中误差和定向边坐标方位角中误差2个方面进行精度评价。实验结果表明:通过设置陀螺全站仪内置自动测量程序,可以有效提高设备测量效率和精度。

In this paper,aiming at the problem existing in the calculation of the orientation of traditional gyro total station,we design the calculation program for downhole coordinate azimuth according to the operation procedure to realize auto orientation surveying,and carry out accuracy assessment from errors of observed values and directional edge coordinate azimuth. The result shows that the efficiency and accuracy of surveying is improved effectively by setting up the automatic measurement program of gyro total station.
