The Simulink Simulation of the INS on the Near Space Hypersonic Vehicle

The near space hypersonic vehicle has strong dynamic features and precise attack capability.The navigation system is the key to ensure the high precision of the vehicle.The inertial navigation system(INS) can provide the all-weather and full-state movement information of the vehicle.And it also takes the advantages of reliability and continuous output.Thus,the INS is the core navigation system of the near space hypersonic vehicle.In this paper,the simulink and M-file are used to establish the inertial navigation system of hypersonic vehicle,and simulation and research are conducted for the system.The simulink model is completed for the INS on the hypersonic vehicle,and the feasibility of the model is verified as well.The tracks of the hypersonic vehicle are simulated,and the effects of the vehicle velocity on the centripetal acceleration and Coriolis acceleration are analyzed.The results have reference values for the study of the inertial navigation system on the hypersonic vehicles.
