Magnetic bearing wheels for very high pointing accuracy satellite missionsInertia wheels used as actuators in Attitude Control Systems remain the most frequently encountered solution for all types of scientific or military space missions. The magnetic levitation of the flywheel leads to increased performance, which will be necessary for the high pointing accuracy missions in the next decade. For military and commercial earth observation missions, for optical link telecommunication missions, as well as for metallurgical process missions under microgravity conditions, the need for platform stability will become stronger and stronger. Work in progress on the Magnetic Bearing Reaction Wheel, dedicated to the HELIOS military earth observation satellite, is presented. The HELIOS program is very demanding in terms of pointing accuracy. The main features of this wheel and its overall characteristics are given.
