When we need to measure the magnetic field with good accuracy, the precise determination of the sensing directions in the absolute coordinate is essential. We have to know the precise attitude of the spacecraft as well as the precise sensing directions in the frame of the spacecraft. In the case of spin-stabilized spacecraft, the three magnetic field components measured by the magnetometer show time-varying sinusoidal wave form. The alignment angles of the sensing direction can be computed from the amplitude and phase of the sinusoidal wave form. When the sensitivity of and angles between the three sensor elements are precisely calibrated in the ground experiment, the sensing directions in the spacecraft reference frame are expressed by two alignment angles., α and β. There are three solutions of the pair of the alignment angles, αandβ. We applied the calculation method shown here to the data from MGF onboard the Arase satellite. The alignment angles are determined with the accuracy of 0.05deg and 0.2deg for the +/-8000 nT and +/-60000 nT ranges, respectively.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1830015000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-RM-18-008","subitem_description_type":"Other"}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20637/JAXA-RM-18-008/0001","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2224","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構宇宙科学研究所太陽系科学研究系(JAXA)(ISAS)"},{"subitem_text_value":"名古屋大学宇宙地球環境研究所"},{"subitem_text_value":"国立天文台RISE月惑星探査検討室"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Department of Solar System Sciences, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"},{"subitem_text_language":"en","subitem_text_value":"Institute for Space-Earth Environmental Research, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Research of Interior Structure and Evolution of solar system bodies, National Astronomical Observatory of Japan"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松岡, 彩子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"寺本, 万里子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"野村, 麗子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsuoka, Ayako","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Teramoto, Mariko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nomura, Reiko","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":"2020-01-31"}],"displaytype":"detail","filename":"AA1830015000.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1830015000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2435/files/AA1830015000.pdf"},"version_id":"5cd91b44-94fd-4032-bca9-7ad9112a85a2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Arase","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ERG","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"MGF","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"magnetic field","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"alignment","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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"スピン衛星に搭載した磁力計センサの軌道上データを用いたアライメント解析手法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スピン衛星に搭載した磁力計センサの軌道上データを用いたアライメント解析手法"}]},"item_type_id":"3","owner":"1","path":["1101","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-24"},"publish_date":"2019-01-24","publish_status":"0","recid":"2435","relation_version_is_last":true,"title":["スピン衛星に搭載した磁力計センサの軌道上データを用いたアライメント解析手法"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:37:28.309275+00:00"}
