Recently, this orbit is deteriorated by numerous pieces of space debris which is caused by collisions of satellite, breakups and so on. In order to maintain human activities in space, we have to cope with the space debris problem as soon as possible. Currently radar equipments are primary methods to observe LEO debris. Optical observation has an advantage of low cost, although it is effected by lighting condition of the sun and weather. The optical observation system consisted of large number of cost-effective CCDs and high-speed PCs at various sites in the world may overcome the current radar observation network. We have examined the possibilities of precise orbit determination using two observation sites containing 40 sets of optical equipments. Simulations using STK have shown that identical objects were recognized from the data of 4 individual equipments installed on 2 separate sites using the lots of circular orbital elements calculated from many observation data. This enables us to determine orbits of many un-cataloged LEO objects precisely.","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: AA0062322037","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":"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)"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"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)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"柳沢, 俊史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"黒崎, 裕久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yanagisawa, Toshifumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurosaki, Hirohisa","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":"62322037.pdf","filesize":[{"value":"2.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"62322037.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3937/files/62322037.pdf"},"version_id":"aeb889c5-e4ee-4ec5-9483-9cff3addd1c8"}]},"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":"低軌道デブリ地上光学観測システムの検討","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低軌道デブリ地上光学観測システムの検討"}]},"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":"3937","relation_version_is_last":true,"title":["低軌道デブリ地上光学観測システムの検討"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:51:43.560815+00:00"}
