探讨了地理跟踪过程中光电吊仓惯性定位的技术途径。在随机调转的光电稳瞄平台上增设加速度计，使之与陀螺组成惯性测量组件，同时向稳瞄系统和导航系统提供信号；光电稳瞄平台在运动中完成瞄准的同时，解算出平台的姿态矩阵；通过平台环架转动夹角的角度量，获得吊仓姿态矩阵，以此得出吊仓的加速度在导航坐标系上的分量，最终完成航迹推算。理论分析和验证试验表明：利用光电吊仓中的惯性组件可以获得光电吊仓的位置和姿态。

The technical solution for electro-optical pod inertial orientation during the geographic tracking was discussed. An accelerator was added in the stabilized platform,which could rotate in azimuth and elevation. The accelerator was combined with the gyroscope on board to form an inertial measurement unit,which provided the signals to servo-gimbal driving system and navigation system. The attitude matrix of the moving platform could be resolved when the stabilized sight was pointing at a target. By use of the rotation angle of the gimbals,the pod attitude matrix was obtained. The component of the pod acceleration value in the navigation coordinate system was calculated,and the derivation of the flight path was realized.The theoretical analysis and verification test indicate that the orientation and attitude of the electro-optical pod can be obtained with inertial measurement unit.
