Urgent countermeasure for satellite breakup due to collision is required especially for Low Earth Region because approximately 70 percent of tracked objects are concentrated to the region. Collision avoidance maneuver based on precise tracking information is one of effective measure to prevent collision. Current size limitation of steady tracking operation for LEO region is about 10 cm in diameter. We propose space-based optical sensor for debris placed in LEO region as a tracking capability improvement method. Proper capabilityassessment for LEO to LEO observation geometry is required to propose effective system. We develop space-based observation simulator as an assessment tool and consider suitable algorithms of initial orbit determination, correlation and filter. Current status of the simulator and algorithms consideration results, and technical problems are reported.","subitem_description_type":"Other"}]},"item_5_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_5_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_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0062322032","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JAXA-SP-13-018","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構(JAXA)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"item_5_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":"宇宙航空研究開発機構研究開発本部(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構研究開発本部(JAXA)"},{"subitem_text_value":"株式会社IHI"}]},"item_5_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":"Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Aerospace Research and Development Directorate, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"IHI Corporation"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田川, 真"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"花田, 俊也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"柳沢, 俊史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松本, 晴久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"北澤, 幸人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tagawa, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hanada, Toshiya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yanagisawa, Toshifumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsumoto, Haruhisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kitazawa, Yukihito","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":"2020-01-16"}],"displaytype":"detail","filename":"62322032.pdf","filesize":[{"value":"854.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"62322032.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3932/files/62322032.pdf"},"version_id":"34f32b6c-6fcd-45cb-bca2-36ccad81ded5"}]},"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":"軌道上光学センサによるLEO デブリ観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"軌道上光学センサによるLEO デブリ観測"}]},"item_type_id":"5","owner":"1","path":["870","1505","1831","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"3932","relation_version_is_last":true,"title":["軌道上光学センサによるLEO デブリ観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:51:50.032513+00:00"}
