摘　　要：以单轴稳定系统为子系统，采用与主惯导系统的速度匹配方式设计卡尔曼滤波器，完成了单轴系统的飞行传递对准。仿真结果表明：设计的滤波器可以有效的提高单轴稳定系统的对准精度。The low - cost INS (Inertial Navigation System) with single axis stabilization is still quite useful for tactical missiles in China.Velocity transfer alignment means that the velocity information of INS with single axis stabilization is aligned with that of master INS. The velocity transfer alignment is done with a simplified Kalman filter. In the design of this filter, this paper discusses how to compensate for arm effect and how to prefilter the denection of missile. Theoretical derivation and digital simulation indicate that the designed Kaiman filter can be expected to adjust attitude information of INS with single axis stabilization to satisfactory precision during flight.
