摘　　要：以某飞行器在不同阶段采用不同惯导系统为背景,基于平台惯导系统输出信息,引用新息相关自适应滤波理论,分析设计了信息校正网络,对捷联惯导系统进行误差修正。仿真结果表明方法有效。With different INS used in different phase in some aerocraft as background,based as information of PINS,hereining the error equation of SINS relative to PINS,excerpting the theory of new-info adaptive filtering,an emendation network is designed through analyzing earnestly.And it is used to emendate the error of SINS.The simulation results show that the method is availability to the error emendation of strapdown inertial system.

关 键 词：反馈校正 捷联惯性导航 误差修正 自适应滤波
