Abstract：This paper simply introduces hypersonic cruise aircraft and puts forward SINS/GPS/CNS navigation as midcourse navigation of it through the analysis of several universally integrated navigation models. SINS is calculated by quaternions and
the integrated navigation system is simulated by federated Kalman filtering method in this paper. Track generator is used to generate a track and other correlation parameters of hypersonic cruise aircraft, then simulation can be made at the base of it.
While simulation results show the feasibility of integrated SINS/GPS/CNS system as midcourse navigation of hypersonic cruise aircraft.
