陀螺定向中天法容许的时间差

Permissible Time Difference of Gyroscopic Orientation Culmination Method

本文阐述了通过解析计算陀螺仪定向中天法的近似北偏离陀螺子午线的改正数，进而列出固定状态下陀螺轴绕其平衡位置的摆动方程，解析求出容许的时间差。

Abstract In this paper,the correction numerical value of approximatly northrly deviating from the gWoscopic meridian of the gyroscopic orientation culmination method is analytically calculated,and then the oscillation equation of the gyroscopic axis round it's balance position is derived,and the permissible time difference is analytically found out.
