This paper describes motion analysis of a tethered pico-satellite. Its attitude and translation are controlled by a reaction wheel utilizing tether tension and by tether tension, respectively. A reaction wheel is actuated based on feedback information of angular velocity, and tether tension is controlled by torque transmission device. Especially, two tension control strategies were experimented. One is keeping constant tension, and the other is active tension control. The microgravity experiments by parabolic flight of an airplane were performed, in order to evaluate the controls. It is noted that attitude of the tethered body performed rotational vibration and it was damped by the reaction wheel control. Also, difference of keeping constant tension and active tension control was confirmed.
