The Attitude Tracking Maneuvers of Spaceborne Spotlight SAR

摘要：

The spotlight mode of spaceborne SAR platforms often have to point its payload to immobile target on the ground which means the satellite attitude have to follow a specific trajectory in a fixed time span. In this paper, the attitude angle, angular velocities and angular accelerate are derived. A PD control law with feedforward is developed to achieve the purpose. The approach is verified using numerical simulation with external disturbance and uncertain model.
