摘　　要：以高超声速飞行器为对象,建立了卫星/惯性组合导航模型。选择组合系统的状态量并建立状态方程,推导位置观测方程和速度观测方程,通过位置、速度交替组合实现卫星/惯性系统的组合。通过仿真验证算法的有效性,仿真结果表明卫星/惯性组合导航可以得到较好的位置和速度信息,适中的姿态精度信息。A model of satellite/inertial integrated navigation for hypersonic flight vehicles was proposed. With the de- velopments of hypersonic flight vehicle and the satellite navigation system,the research of satellite/inertial integrated nav- igation is significance. First, the states of the integrated navigation are selected and the state equation is established. Then, the position observation equation and the velocity observation equation are given. So, the integrated system is imple- ment using position integration and velocity integration alternately. Finally, the efficacy of the presented algorithm is dem- onstrated by simulation. Simulation results that satellite/inertial integrated navigation can give good position and velocity information and moderate precise attitude information.
