Two types of satellites which are proposed by Institute for Unmanned Space Experiment Free Flyer are discussed. From some numerical analysis, it is shown that these satellites are enough stable against air drag, solar pressure and the effect of orbital inclination (30 degrees). Furthermore, a new method is proposed based on potential energy to estimate the stability of satellite. By using the potential energy, not only equilibrium states but also the degree of stability in the neighborhood can be estimated. The potential energy, which is caused by gravitational force and centrifugal force, is considered. At first, the stability about the satellite's attitude is estimated based on the potential energy. It is shown that stability around yaw axis is extremely lower than the other two axes. Then, the change of stability which depends on the satellite's shape is shown. From the result, it is confirmed that the stability around yaw axis can be improved by changing the aspect ratio of solar panel, and the aspect ratio has to be over 0.4 to keep the pitch motion stable.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0045915015","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Institute of Space and Astronautical Science (ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"北海道大学 大学院工学研究科"},{"subitem_text_value":"北海道大学 大学院工学研究科"},{"subitem_text_value":"北海道大学 大学院工学研究科"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Hokkaido University Graduate School of Engineering"},{"subitem_text_language":"en","subitem_text_value":"Hokkaido University Graduate School of Engineering"},{"subitem_text_language":"en","subitem_text_value":"Hokkaido University Graduate School of Engineering"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"石村, 康生"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"和田, 充雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高井, 伸明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ishimura, Kosei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Wada, Mitsuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takai, Nobuaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"SSPS","subitem_subject_scheme":"Other"},{"subitem_subject":"USEF","subitem_subject_scheme":"Other"},{"subitem_subject":"重力勾配トルク","subitem_subject_scheme":"Other"},{"subitem_subject":"姿勢安定性","subitem_subject_scheme":"Other"},{"subitem_subject":"ポテンシャルエネルギー","subitem_subject_scheme":"Other"},{"subitem_subject":"遠心力","subitem_subject_scheme":"Other"},{"subitem_subject":"重力","subitem_subject_scheme":"Other"},{"subitem_subject":"数値解析","subitem_subject_scheme":"Other"},{"subitem_subject":"太陽放射","subitem_subject_scheme":"Other"},{"subitem_subject":"研究開発","subitem_subject_scheme":"Other"},{"subitem_subject":"アスペクト比","subitem_subject_scheme":"Other"},{"subitem_subject":"ヨー","subitem_subject_scheme":"Other"},{"subitem_subject":"SSPS","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"USEF","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravity gradient torque","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"attitude stability","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"potential energy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"centrifugal force","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gravitation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"numerical analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"solar radiation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"research and development","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"aspect ratio","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"yaw","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"重力安定型太陽発電衛星の姿勢安定性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"重力安定型太陽発電衛星の姿勢安定性"}]},"item_type_id":"5","owner":"1","path":["1579","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"8165","relation_version_is_last":true,"title":["重力安定型太陽発電衛星の姿勢安定性"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:27:27.772055+00:00"}
