【 摘 要 】

The attitude determination problem of Earth Orientation gyro-less spacecraft is studied in this paper. Considering the sensitivity of the initial attitude error for EKF, a new non linear attitude determination filter is developed by using the Special Orthogonal Group SO (3) which avoids any algebraic reconstruction of the attitude from reference vectors. Lyapunov analysis results for the proposed the filter is derived that ensure global stability of the error. The simulation results show that the estimation of attitude and angular velocity converge to the real in the Earth Orientation mode.
