Based on experience with the small satellite BIRD BIRD (Bispectral Infra-Red Detection) of German Aerospace Center (DLR), this paper proposes a mathematical and numerical approach to compute the most effective dipole moment while taking into account the spatial dipole characteristic of the magnetic actuator system. The control torque is obtained via quaternion feedback control. The control algorithm is tested and verified by orbit simulation. A three-axis pointing accuracy of better than 5 deg and a more efficient utilization of the actuator are achieved. The proposed control algorithm will also be implemented in the upcoming TET-1 on-orbit verification (OOV) mission and the DLR 'Compactsat'. The algorithm as well as the full attitude control system will be verified via the introduced state-of-art air attitude control test bed.
