INS error modification method based on pseudo line-of-sights intersection for cruise missile

  • 摘要: 针对飞航导弹惯性导航系统(INS, Inertial Navigation System)单独使用时存在位置和速度估计误差发散的问题,在不需要弹目距离信息的情况下,提出了一种基于对航路上单个已知地标连续、被动观测的INS误差修正方法.根据导弹与地标间的相对运动关系,采用虚拟视线交会的方法,将问题转化为多虚拟地标协同定位导弹问题.在此基础上,利用最小二乘思想,实现了导弹位置的有偏估计.以估计得到的有偏位置信息和基于大气系统得到的INS速度误差大小作为观测量,应用考虑系统误差估计补偿的卡尔曼滤波,实现了导弹位置和速度的无偏估计.仿真结果验证了方法的有效性.
