| Abstract: | 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. |
