摘要
在惯组瞄准过程中,惯组测量单元和光管准直偏差角测量单元是在不同的测量坐标系下完成的,直接进行瞄准角度的合成会带来较大的耦合误差。针对此问题给出了一种惯组瞄准角度的解算方法,通过矩阵方式求得坐标系之间的变换关系,得到输出基准在地理坐标系中的姿态角度,并通过瞄准解算,获得目标棱镜的方位角度。
In the process of inertial group aiming,the inertial group measuring unit and the optical tube collimation deviation angle measurement unit are completed under different measuring coordinates,and the direct synthesis of aiming angle will lead to large coupling error.Aiming at this problem,a method for solving the aiming angle of inertia group is presented,and the transformation relationship between each coordinate system is obtained by matrix method.The attitude angle of the output reference in the geographical coordinate system is obtained and the azimuth angle of the target prism is obtained by aiming calculation.
