The missions of the Artemis and DRS's (Data Relay Satellites) (both part of the Data Relay and Technology Mission (DRTM) program of ESA) lead to spacecraft configurations with disturbance torques not usually encountered in telecommunication satellites. Because of these specific disturbance torques, new concepts for attitude control were considered. The derivation of the concepts and justification of their selection for the Artemis and the DRS are shown. These concepts are evolved from the classical 'biased momentum' attitude control used on many geostationary satellites but provide a better capability of handling large torques due to: solar radiation pressure, moving antennas, or the use of ion propulsion. The proposed attitude control system (two degrees of freedom with solar sailing) will provide a large growth capability for future telecommunications satellites while retaining the essential features of classical attitude control systems.
