摘　　要：空空导弹具有重量轻、体积小,工作时间短等显著特点,传统的弹载导航系统主要是捷联惯性导航系统,它包括陀螺和加速度计,将一种新型导航系统——无陀螺捷联惯导/GPS组合导航系统应用到空空导弹领域;无陀螺捷联惯导系统(GFSINS)中只包含有加速度计,基于一种九加速度计配置方式,推导了GFSINS系统方程,并给出了导航系下GFSINS/GPS组合导航系统的卡尔曼滤波方程;仿真结果表明:GFSINS/GPS组合导航系统应用到空空导弹领域具有可行性。The air-to-air missile has a special feature of low weight,small volume,short working time. The common navigation system of air-to-air missile is almost strapdown inertial navigation system,and it contains gyroscopes and accelerometers.In this paper,a new navigation system （GFSINS/GPS integrated navigation system）is applied to the field of air-to-air missile.The GFSINS only contains accelerometers and equations of GFSINS are derived based on a configuration of nine accelerometers.In the end,the kal-man filter equations of GFSINS/GPS integrated navigation are derived out in navigation coordinate.The simulation results indicate that it has strong feasibility to apply GFSINS/GPS integrated navigation system in the field of air-to-air missile.
