According to the problem of attitude control of satellite dynamic scanning imaging, the dynamic model of the satellite attitude was built and the specific requirement of dynamic scanning imaging tasks for attitude control was analyzed. Combined with the dynamic scanning imaging tasks, a typically attitude maneuver scheme was designed. The required control moment of the process of dynamic scanning imaging was estimated. A pitching maneuver control law based on the expected torque and real-time attitude of satellite was developed, and the steering law of five pyramid configuration gyros was given. A numerical simulation was presented for the designed control law based on a maneuver task. The simulation results proved that the proposed scheme can satisfy the requirement of attitude control of dynamic scanning imaging satellite.
