This method should lead to simple attitude keeping, but the motion showed nutation divergence in March 2007. This paper shows that the cause of the instable motion lies in the difference between the axis of wheel and of inertia, and a way to avoid this instability is proposed., 資料番号: AA0063718021}, pages = {126--131}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Instability analysis of Hayabusa attitude control by using one momentum wheel}, year = {2008} }
