| 摘 要： | 针对空间武器捷联惯性导航系统SINS(Strapdown Inertial Navigation System)动基座快速、精确初始对准问题,建立了空间环境下武器SINS的动基座误差模型,并考虑武器SINS的惯性器件误差.根据姿态传递对准原理,推导了姿态匹配方式下卫星与武器SINS姿态角之差的量测方程.在此基础上,建立了空间武器SINS传递对准的数学模型,设计一种快速对准卡尔曼滤波器.计算机仿真结果验证了该模型的有效性.在10s时间内,可获得与卫星姿态测量系统姿态精度相当的对准精度,同时还能实现武器SINS惯性器件误差的准确标定.

| Abstract: | Aiming at the problem of rapid and accurate transfer alignment for the space weapon strapdown inertial navigation system(SINS),the error model of weapon SINS was established and the errors of inertial elements were considered.The attitude matching was selected,and the measurement equation of the attitude error between space weapon SINS and satellite was deduced based on the principle of attitude transfer alignment.Based on these,the filter model of space weapon SINS was established and a rapid Kalman filter... |
