当惯性陀螺工作在方位姿态时，有一定的斜坡漂移，它将引起惯性导航系统中的严重的航向和位置误差，所以有必要估计和补偿它。

There exists a slope drift in an integral gyro when it is used as an azimuth gyro, which may cause serious heading and position errors in the Inertial Navigation System (INS).

临近方位标度盘有一个方向标志，需要对着方位标度盘外部边缘来读取所指示的选定航向。

Selected heading. A heading marker, located adjacent to and read against the outer edge of the azimuth dial, indicates the selected heading.

针对这种情况，探讨了一种利用机(舰)载光测设备测量方位标修正惯导航向偏差的方法。

This paper discusses a new method that utilizes optical measuring instruments to measure the azimuth points and collimates the navigation deviation.
