针对目前国内弹道导弹导航系统单一的情况,文中提出一种滤波算法。该算法将捷联星光跟踪仪(Strapdownstartracker,SST)的姿态信息、高速GPS的位置、速度信息与捷联惯导进行组合滤波,全面提高了导航的姿态、速度和位置精度。最后以该算法为核心,设计并实现了用于弹道导弹的GPS/SST/SINS组合导航系统实时仿真平台。仿真结果表明,该滤波算法稳定可靠,系统精度达到国外同等水平。
Aiming at the single situation of the domestic ballistic missile navigation system, a filtering algorithm is proposed in this paper. The algorithm combines the attitude information of Strapdownstartracker (SST), the position and velocity of high-speed GPS with SINS, and improves the attitude, velocity and position accuracy of the navigation. Finally, based on this algorithm, a real-time simulation platform of GPS / SST / SINS integrated navigation system for ballistic missiles was designed and implemented. The simulation results show that the filtering algorithm is stable and reliable, and the system accuracy reaches the same level abroad.
