The report describes a concept for a satellite gravity gradient stabilization system. It utilizes active damping to reduce the oscillation time constant and the initial capture time and also to reduce the oscillation magnitude (amplitude). The active damper described is conceptually capable of achieving high reliability. It consists of an elastically suspended control rod driven by an electromagnetic actuator; the actuator is excited by a servo amplifier which is controlled by an optical sensor. This attitude control concept may be implemented to provide automatic correction of errors caused by bias torques. (Author)
