通过方位精对准状态在北西天坐标系和东北天坐标系两次定位测量水平陀螺漂移，在水平精对准状态下记录北向速度并采用最小二乘法解算方位陀螺漂移。
Horizontal gyro drift is measured in state of azimuthal alignment by the two localization laws of the three directions of north, west and up, as well as east, north and up.
快速高精度寻北仪利用惯性技术，可为精确打击武器系统提供北向基准。
The fast high accuracy north-seeker, makes use of inertial technique, can provides north face basis for precision attack weapon system.
在实现寻北功能后，再通过施加力矩的方法使陀螺仪主轴转到真北方向，使系统工作于方位仪模式，则陀螺主轴就能始终保持在真北方位上，不断地指示车体相对北向方位的方位角。
After that, rotating the sensitive axis of the gyro to point the true north, the instrument is working in the azimuth mode to constantly display azimuth angle of the carrier.
