| 摘 要： | 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(Strapdown star tracker, 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.

| Abstract: | Considering the domestic single navigation system of the ballistic missile, a new filter method is presented. The method integrates the information of the strapdown star tracker (SST) attitude, the position and the velocity of a high speed GPS with a strapdown inertial navigation system (SINS) information into one filter, thus improving the precision of the attitude, the velocity, and the position. Finally, the GPS/SST/SINS simulation platform is designed. Simulation results demonstrate that the filter is robust and reliable, and the precision rises to the comparative level abroad. |
