摘要
针对空空导弹的特点,对适用于空空导弹的SINS/GPS组合导航系统进行了研究,明确了组合导航系统对火控系统的设计约束,设计了冗余空空导弹组合导航系统结构使导航系统更健壮;选择了当地地理系作为组合导航系统的坐标系,推导了在此坐标系下组合导航算法状态方程和量测方程;最后进行了蒙特卡洛法仿真,验证了组合导航算法设计的可行性与实用性,具有良好的工程应用前景。
In view of the characteristics of airborne missile,the SINS/GPS integrated navigation system for airborne missile was studied,fire control system arithmetic and integrated navigation system structure were designed;Local geographical coordinates was selected as integrated navigation coordinate frame.The error state and measurement equations under local geographical coordinates were derived.Finally,Monte Carlo simulation was adopted.The simulation results show that the integrated navigation arithmetic is feasible and can be applied,which indicates good prospect in aviation application.
