摘　　要：为了保证捷联惯导系统能够正确给出炮管高低角和方位角,必须对捷联惯组和炮管之间的安装误差角进行标定。介绍了利用经纬仪进行安装误差角标定的原理和方法,还提出另外两种计算安装误差角方法,包括利用欧拉角微分方程进行近似积分方法和利用主惯导与子惯导间的传递对准方法。经对比上述三种方法是等效的,其共同特点是炮管必须作高低角运动,并且要求在运动前后横滚角变化很小。最后,通过调炮试验验证了标定方法的可行性。In order to providing elevation and azimuth for gun barrel via strapdown inertial navigation system （SINS）, the misalignment angle calibration between strapdown inertial measurement unit（SIMU） and gun barrel is necessary. Using theodolite goniometer, the principle for misalignment angle calibration is introduced, and two more methods are also proposed to process the gun slaving test data, which include the approximate integral of the Euler angle differential equation method and the transfer alignment method between main SINS and slave SINS. The above three calibration methods are proved to be identical. In these methods, an elevation angle movement for gun barrel is demanded but with very small roll angle changed, and it canl be well satisfied in the gun salving test. Finally, the gun slaving test results prove that the proposed calibration methods are correct and feasible.
