pitch gyro and azimuth gyro 垂直陀螺仪和水平陀螺仪
The input axis of the azimuth gyro under this condition is vertical, and pendulum unit is nulled.
在这样情况下方位陀螺的输入轴是处于垂直位置，同时摆锤单元在零位。
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).
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。
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.
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。
