WebAttitude estimation is often more difficult for spinning spacecraft than for three-axis stabilized spacecraft. The parameters representing the spacecraft attitude and its time rate of change vary more rapidly in the spinning case, and gyro rate measurements are often lacking, requiring Euler's equations for modeling the attitude dynamics. WebThe attitude estimation problem whose states evolve into Lie groups with invariance properties is a benchmark and motivating application, and various Kalman type filtering methods have been developed by researchers for attitude estimation [7, 8], target tracking and so on [9, 10].
