给出了可提高战术弹道导弹射击精度的GPS／SINS组合制导模型。在给出多模Kalman滤波（MKF）数学模型的基础上，建立了可对GPS／SINS组合制导进行在线故障检测、故障隔离和系统重构的品质控制方案。对于系统的重构，提出了鲁棒性处理方法。仿真结果表明：基于MKF的GPS／SINS组合制导与单独捷联惯导相比，可使导弹射击精度得到明显提高，组合制导的品质也得到了有效控制。
A GPS / SINS combined guidance model that can improve the shooting accuracy of tactical ballistic missiles is given. Based on the mathematical model of multi-mode Kalman filter (MKF), a quality control scheme for on-line fault detection, fault isolation and system reconfiguration of GPS / SINS combined guidance is established. For the reconstruction of the system, a robust processing method is proposed. The simulation results show that the MKF-based GPS / SINS combined guidance system can significantly improve the precision of the missile firing and the quality of the combined guidance system compared with the single SINS.
