GAS のデータベースを利用することで, オーロラとプラズマ粒子に加えて, 沿磁力線電流の影響も同時に確認することができ, れいめい衛星データ解析が大きく前進することが期待される. また, ノイズ成分の大きな磁力計であっても, 沿磁力線電流の影響を精度よく測ることができており, 超小型衛星等への磁力計搭載について, 重要な意味を持っている.","subitem_description_type":"Abstract"}]},"item_3_description_17":{"attribute_name":"抄録（英）","attribute_value_mlt":[{"subitem_description":"Reimei satellite contributes to the developments of auroral sciences, by the simultaneous observations of auroral emissions and auroral particles. Within the limits of a small spacecraft mission, the main mission instruments are only the Multi-spectral Auroral imaging Camera (MAC), the Electron Energy Spectrum Analyzer/Ion Energy Spectrum Analyzer (ESA/ISA), and the plasma CurRent Monitor (CRM). The data analysis of the Reimei satellite is primarily conducted by using the two mission instruments such as MAC and ESA/ISA. The Geomagnetic Aspect Sensor (GAS) is onboard the spacecraft for attitude control and it can make output of high-time resolution magnetic field data. Because of lack of calibration it has not been possible to use GAS data for scientific discussion. The noise level of the data is quite high, compared to the variation of magnetic fields in space, because the magnetometer is not in an optimal position onboard the spacecraft. We calibrated the GAS data using coordinate transformation, averaging, and offset subtraction. As the magnetic field variation of calibrated GAS data corresponds to the characteristics of auroral particles well, it is considered to be affected by field-aligned currents (FACs). We can now estimate the FAC from the magnetic field variations from GAS data. Based on the database of calibrated GAS data, Reimei data analysis is expected to make progress, where three instruments can clarify aurora behaviors and the auroral particles, monitoring FAC effects. Finally, we note that calibrated GAS data can detect even the effects of a weak FAC in spite of the large noise level of GAS raw data. This suggests that magnetometers onboard other similar microsatellites may also be used for FAC studies.","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: AA1630049006","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-RR-16-007","subitem_description_type":"Other"}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.20637/JAXA-RR-16-007/0006","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_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1113","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1192675X","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"高知工業高等専門学校"},{"subitem_text_value":"高知工業高等専門学校"},{"subitem_text_value":"名古屋大学宇宙地球環境研究所"},{"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)"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Technology, Kochi College"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Technology, Kochi College"},{"subitem_text_language":"en","subitem_text_value":"Institute for Space-Earth Environmental Research, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Department of Solar System Sciences, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"益岡, 葵"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高田, 拓"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"平原, 聖文"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"浅村, 和史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Masuoka, Aoi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takada, Taku","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hirahara, Masafumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Asamura, Kazushi","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":"AA1630049006.pdf","filesize":[{"value":"3.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1630049006.pdf","url":"https://jaxa.repo.nii.ac.jp/record/1852/files/AA1630049006.pdf"},"version_id":"9280a682-e791-45b3-a203-7188db3e4d84"}]},"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":"れいめい衛星搭載磁力計GASのデータベース作成・整備; 沿磁力線電流の推定のために","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"れいめい衛星搭載磁力計GASのデータベース作成・整備; 沿磁力線電流の推定のために"}]},"item_type_id":"3","owner":"1","path":["47","1402","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-20"},"publish_date":"2017-04-20","publish_status":"0","recid":"1852","relation_version_is_last":true,"title":["れいめい衛星搭載磁力計GASのデータベース作成・整備; 沿磁力線電流の推定のために"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:38:04.685172+00:00"}
