摘　　要：针对INS/CNS组合导航系统动基座对准的问题,设计了一种基于惯导误差全面校准模式的动基座对准方法。在INS/CNS组合系统姿态、位置量测信息的基础上,推导了INS/CNS组合系统线性化状态方程,同时分析建立了该对准模式的量测方程,利用Kalman滤波技术设计了基于该信息融合方法的动基座对准方案,通过仿真分析验证了该方法动基座条件下对准的有效性,仿真结果表明在舰船动态航行条件下该方法可以在60分钟内达到优于15''的航向精度。Aiming at the problem of the alignment of the dynamic base of the INS/CNS integrated navigation system, a method of dynamic base alignment based on the inertial navigation error comprehensive calibration mode is designed. Based on the attitude and position measurement information of the INS/CNS combination system, the linearized state equation of the INS/CNS combination system is derived, and the measurement equation of the alignment mode is analyzed and established. The Kalman filter technology is used to design the information based on this information. The dynamic base alignment scheme of the fusion method is verified by simulation analysis. The simulation re-sults show that the method is effective under dynamic base alignment. The simulation results show that the method can achieve better than 15’’ within 60 minutes under the dynamic navigation conditions of the ship heading accuracy.
