用中天法进行矿井定向的一些问题

Some problems existed in mine orientation by using transit method

本文论述了中天法定向时陀螺北方向值的计算公式、理论精度、观测值及计算值的限差；一次测量中误差，并以ＷＩＬＤＧＡＫ１陀螺经纬仪为例进行了实际定向。

In this paper,the mathematical formula of Gyro north direction value ,the theoretical precision,limiting error of observed value and calculated value and mean square error of a measurement in the orientation by using transit method are described.Further more,the practical orientations are conducted with Wild GAK 1 Gyro theodolite and comparison with theoretical precision is also made.
