Light curves are brightness of space objects as a function of time and are obtained by ground-based observations. In order to demonstrate this technique, 'Q-Li' the 3U Cubesat for Light Curve Inversion is being developed in Kyushu University. The primary mission of Q-Li is the on-orbit verification of the light curve inversion by comparing actual state and estimated one by light curve measurements. To this end, Q-Li deploys a membrane to reflect sunlight so that one can be observed from the ground. Q-Li measures her own attitude angles and angular rates in orbit and transmits them to the ground. As the secondary mission, Q-Li detects tiny debris collisions with the membrane by sensors located on its surface. In this workshop, not only the whole systems of Q-Li but also the deployment mechanism of the membrane and light curve inversion technique are presented.","subitem_description_type":"Other"}]},"item_4_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_4_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_4_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA1830034049","subitem_description_type":"Other"}]},"item_4_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-18-011","subitem_description_type":"Other"}]},"item_4_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_4_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_4_source_id_22":{"attribute_name":"ISSNONLINE","attribute_value_mlt":[{"subitem_source_identifier":"2433-2232","subitem_source_identifier_type":"ISSN"}]},"item_4_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"九州大学"},{"subitem_text_value":"九州大学"},{"subitem_text_value":"九州大学"},{"subitem_text_value":"九州大学"}]},"item_4_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Kyushu University"},{"subitem_text_language":"en","subitem_text_value":"Kyushu University"},{"subitem_text_language":"en","subitem_text_value":"Kyushu University"},{"subitem_text_language":"en","subitem_text_value":"Kyushu University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"松下, 悠里"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"荒川, 稜平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉村, 康広"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"花田, 俊也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsushita, Yuri","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Arakawa, Ryohei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshimura, Yasuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hanada, Toshiya","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":"2020-01-15"}],"displaytype":"detail","filename":"AA1830034049.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AA1830034049.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2853/files/AA1830034049.pdf"},"version_id":"5ddcf73b-56ae-425a-87ac-888e358d6d18"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Q-Li the 3U Cubesat for Light Curve Inversion","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Q-Li the 3U Cubesat for Light Curve Inversion","subitem_title_language":"en"}]},"item_type_id":"4","owner":"1","path":["795","1502","1828","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-15"},"publish_date":"2019-03-15","publish_status":"0","recid":"2853","relation_version_is_last":true,"title":["Q-Li the 3U Cubesat for Light Curve Inversion"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:15:03.090943+00:00"}
