| 摘 要： | 风浪波动及人员走动等因素给系泊状态下舰载导弹的初始对准带来困难,同时惯性测量组件安装位置与船体摇摆中心不重合所引起的杆臂效应误差又严重影响对准精度.为了解决问题,采用参数辩识法来提取姿态角误差时间二次多项式中的诸系数,从而确定陀螺漂移及姿态角误差,并提出一种在摇摆基座上补偿捷联惯导杆臂效应误差的有效方案.理论分析和仿真计算结果表明:该捷联式自主初始对准方案能有效的解决系泊状态下舰载导弹的初始对准问题.

| Abstract: | A method of independent initial alignment of a marine strapdown inertial navigation system in moorage is studied to arm at the problems which are brought by a base swinging with large angles and centripetal acceleration disturbance on the base. Parameter identification is used to pick up the several coefficients in attitude error expressions in order to identify gyro bias and attitude error. Moreover, an idea that compensates in real time acceleration disturbance on a swing base is addressed. Finally, simulation calculations are given to show the validity of the method. |
