ABSTRACT:
A satellite single axis drag compensation system improves stability and ects damping of movements of a cylindrical proof mass by providing an elongated, perpendicularly magnetized permanent magnet in the core of a current carrying rod that extends coaxially through a central bore of the proof mass, the proof mass being constructed as a composite structure of alternate cylindrical layers of diamagnetic silver and paramagnetic aluminum to reduce magnetic susceptibility thereof.
