Japan's inter-planetary exploration spacecraft "SAKIGAKE" and "SUISEI" employ a mechanically despun antenna which operates at 0.2 rpm and 6 rpm spin rates. This is the first time that an antenna-despin-control system is used in space at an ultra-low spin rate of about 0.2 rpm. The despin control system was developed by incorporating several new techniques and its performance confirmed through the ground tests and the computer simulation. This paper describes the system tradeoff and study of the antenna despin control system developed for "SAKIGAKE" and "SUISEI" together with the flight data.
