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.
