对中天法陀螺定向计算公式的修正

Modification of Transit Method Formula for Gyrotheodolite Orientation

本文推导了中天法陀螺定向计算的原始公式,并将其与现行公式进行了比较。指出了现行公式⊿N=C·α⊿t所存在的偏差,并给出了修正的计算公式。从而保证了中天法定向计算中的应有精度。

In this article, the original formula used for transil method is derived. A comparision between the new formula and that used presently is made to indicale a deviation in N=C·a·⊿t. To insure the orientation accuracy of transit method, the formula of modification is given.
