导线加测陀螺方位角的过程简化探讨

针对地下陀螺定向时间较长、作业强度大、陀螺仪电量等问题,现就陀螺仪传统测量过程（主要是逆转点法）提出简化.通过已知坐标反算操作获得粗北方向的方法取代传统的粗定向过程,可以大大提高定向效率和经济效益,并且能够节省电池电量、节省作业人员体力.文中对比新旧方法在寻找粗北方向的测量结果,从而分析方法的可行性.

Simplifying the process of measuring gyroscope azimuth angle with wires

According to the problems in the underground gyro orientation process which takes a long time,high work intensity and over use of gyroscope power, It presents that simplifying the traditionalmeasurement process （mainly reversal point）. Through the method of using known coordinates the backcalculation and operation can obtain coarse north direction to replace the traditional coarse orientationprocess, which can greatly improve the directional efficiency and economic benefits, save the batteryufespan, and the personnel physical consumption. A comparative analysis is made on the old and newmethods in search for the coarse north direction and measuring results so that the feasibility of this methodcan be tested.
