基于 DGPS 的弹载捷联惯导系统性能评估技术研究

摘要

针对武器系统对弹载捷联惯导系统性能评估要求，对捷联惯导系统对准和导航精度评估方法展开研究，对比目前常用的固定区域平滑和固定点平滑算法的各自优缺点，设计了一种利用导航段载机和导弹惯导滤波数据对导弹惯导传递对准与导航误差进行评估的新算法；对算法进行了充分的数字仿真，仿真结果证明了所设计的算法更实用、更具有工程应用价值。%According to the requirements of the performance evaluation of weapons systems for mis-sile-borne SINS, the accuracy analysis method of SINS transfers alignment and navigation are researched. The advantages and disadvantages of the fixed point and fixed interval smoothers algorithm are compared. A new algorithm using the navigation segment data Kalman filtering for assessment of SINS transfer align-ment and navigation error is designed;software simulation of the new algorithm is adopted, the simulation results prove that this evaluation algorithm for the fixed point and fixed interval smoothers algorithm is more practical and has more engineering value.
