Abstract
The feasibility study has been conducted to build a small satellite (so called 'nano-satellite'), which has 3-kg mass and less than 30-W power, since October in 1998. A 3-axes attitude control experiment of the nano-satellite under micro-gravity field was carried out at Japan Micro-gravity Center (JAMIC) in 2001. The small reaction wheel was used as an actuator for the attitude control developed by Hokkaido Institute of Technology as one of the important key technologies of the nanosatellite. The 3-axes attitude control by using wireless CCD camera (VHF wave) and image processing was demonstrated under micro-gravity.
