A navigation method provides accurate velocity and attitude angle for vehicle’s deep space aviation is proposed. The system regards strap-down inertial navigation as the main navigation system. Assisted with Celestial Navigation System and Doppler Navigation System, it constitutes SINS/CNS/Doppler integrated navigation system through Information Fusion Technology. This paper takes the error of the navigation information as the state vector, uses both celestial method and one-way Doppler measurement from ground stations to establish federated filter to fuse information and finally accomplish the navigating task. Results show that the navigation velocity accuracy is about 0.04m/s, and the attitude angle accuracy is below 1″, which demonstrate this method is fit for Vehicle’s Deep Space Aviation.
