The proposed algorithm utilizes the nonlinear observel to estimate the vehicle's attitude information based on inertial measurement unit. Then the estimated angles and angular velocities are used to stabilize the antenna beam. Experiment results show tha| the proposed algorithm can stabilize the antenna beam when the tracking information is available, indicating that it is competent to the SOTM system.展开更多
