Abstract
The attitude measurement method of satellite navigation for spinning air vehicles is innovatively proposed. As an attitude measurement backup solution for inertial navigation system or magnetometer, based on kinematics principle, the velocity vector from GNSS receiver could be used to measure attitude for spinning air vehicles without any other sensors. The three-dimensional pseudo-attitude kinematics modelling is realized under the condition that the flight angle of attack and sideslip angle are small; the pseudo-attitude is transformed into inertial coordinates through Euler attitude matrix, and its accuracy index meets the actual working requirements.
