Therefore, orbit detemination was performed with estimation of ion propulsion magnitude and direction error. Trajectory Correction Maneuvers (TCM) were accomplished five times by ion propulsion from April to June 2010. Each TCM was performed only by ion propulsion, and Doppler data were monitored to watch the real-time status of TCM accomplishment. The cut-off time of ion propulsion for each TCM was detemined by the result of Doppler change. Doppler monitoring was used for capsule separation evaluation too. We evaluated the separation by the change of the mother ship's attitude and velocity caused by the separation, because the capsule itself could not communicate with ground stations. The Doppler data gap at the separation shows that the capsule separation was accomplished well. The spacecraft and its capsule re-entered to east side of Woomera Prohibited Area (WPA) in Australia successfully on June 13, 2010.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0065115033","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宇宙科学研究所 (JAXA)(ISAS)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11567475","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"富士通"},{"subitem_text_value":"宇宙航空研究開発機構 (JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構 (JAXA)"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Fujitsu"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大西, 隆史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉川, 真"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"竹内, 央"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Onishi, Takafumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshikawa, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Takeuchi, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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 paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Hayabusa Orbit Determination before Re-entry","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Hayabusa Orbit Determination before Re-entry","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1553","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7280","relation_version_is_last":true,"title":["Hayabusa Orbit Determination before Re-entry"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:41:56.741920+00:00"}
