These satellites were spin-stabilized ones. The spin-axis and spin-rate control scheme based upon magnetic torquing was employed on them. For this purpose, a moderately speedy determination of spin-axis direction had been desired. Attitude sensors developed and used for the dtermination were digital sun sensor, infrared horizon-corssing indicator, and the 2 or 3-axis fluxgate magnetometer. The methods used for the dtermination of the spin-axis orientation were the so-called cone-angle method and/or dihedral-angle method. In the following, detailed description of the method is given, followed by the exposition about the computer program and the related ground system including data transmission and processing. Then, the operation of attitude sensors on board \"Taiyo\" is briefly reported. Finally, the results of attitude determination are given together with the discussions about the accuracy and the drift of the spin-axis. The conclusion is arrived at that the spin axis of Taiyo has been kept roughly nomal to the orbital plane within the tolerances required by the mission.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124612000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学理学部地球物理研究施設"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"二宮, 敬虔"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"広川, 英治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"周東, 晃四郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"鈴木, 勝久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NINOMIYA, Keiken","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HIROKAWA, Eiji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SHUTO, Koshiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SUZUKI, Katsuhisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-23"}],"displaytype":"detail","filename":"SA0124612.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124612.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31639/files/SA0124612.pdf"},"version_id":"bb79690e-b7aa-468b-88ac-159e8ec979b1"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"科学衛星「たいよう(1975-014A)」の姿勢決定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"科学衛星「たいよう(1975-014A)」の姿勢決定"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31639","relation_version_is_last":true,"title":["科学衛星「たいよう(1975-014A)」の姿勢決定"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:54:33.876937+00:00"}
