The prediction of re-entry point and time window are important for space debris issues. Orbits of re-entering objects are observed by radar and also estimated using Two-Line Elements obtained from a web site for re-entryprediction analysis. However, accurate observation by radar just before re-entry is difficult due to errors in atmospheric drag prediction. We therefore established a method called the Multi-Stage Observation to solve this problem, and made much progress in observing the objects in the last hours of re-entry in visible paths.This paper presents recent activities of space debris observation and re-entry prediction and their results obtained from three targeted satellites which re-entered in JFY 2011. In addition, means for improving prediction accuracy is further discussed.","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: AA0062322033","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情報・計算工学センター(JAXA)(JEDI)"},{"subitem_text_value":"宇宙航空研究開発機構統合追跡ネットワーク技術部(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構統合追跡ネットワーク技術部(JAXA)"},{"subitem_text_value":"富士通株式会社"},{"subitem_text_value":"富士通株式会社"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"JAXA's Engineering Digital Innovation Center, Japan Aerospace Exploration Agency (JAXA)(JEDI)"},{"subitem_text_language":"en","subitem_text_value":"Consolidated Space Tracking and Data Acquisition Department, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Consolidated Space Tracking and Data Acquisition Department, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"FUJITSU LIMITED"},{"subitem_text_language":"en","subitem_text_value":"FUJITSU LIMITED"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"染谷, 一徳"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"阿部, 旬也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田島, 徹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"足立, 学"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"亀山, 雅也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Someya, Kazunori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Abe, Junya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tajima, Toru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Adachi, Gaku","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kameyama, Masaya","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":"62322033.pdf","filesize":[{"value":"1.8 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"62322033.pdf","url":"https://jaxa.repo.nii.ac.jp/record/3933/files/62322033.pdf"},"version_id":"2f86e70a-656c-49aa-a4b5-4a8ad0a726ef"}]},"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":"再突入物体のレーダ観測及び予測解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"再突入物体のレーダ観測及び予測解析"}]},"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":"3933","relation_version_is_last":true,"title":["再突入物体のレーダ観測及び予測解析"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T08:51:47.771584+00:00"}
