Required velocity increment and recovery time to transfer from the parking orbit to the operational orbit depend on the orbital parameters of the parking orbits and the method of orbital transfer. As for the velocity increment, a LEO (low earth orbit) parking orbit with an orbit inclination, which is identical to that of the operational orbit, is best. However, the recovery time is long. In case that relatively short recovery time is required, a LEO parking orbit with a normal inclination for the launcher is suitable. Super-synchronous transfer method and orbital maneuver from a transfer orbit to the operational orbit at the point of tangency can reduce required velocity increment.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0047897050","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本部"}]},"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_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0918-8053","subitem_source_identifier_type":"ISSN"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"情報通信研究機構"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Institute of Information and Communications Technology"}]},"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":"木村, 和宏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kimura, Kazuhiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"移行軌道","subitem_subject_scheme":"Other"},{"subitem_subject":"パーキング軌道","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙機回収","subitem_subject_scheme":"Other"},{"subitem_subject":"予備衛星","subitem_subject_scheme":"Other"},{"subitem_subject":"速度増分","subitem_subject_scheme":"Other"},{"subitem_subject":"準天頂衛星システム","subitem_subject_scheme":"Other"},{"subitem_subject":"衛星故障","subitem_subject_scheme":"Other"},{"subitem_subject":"LEO","subitem_subject_scheme":"Other"},{"subitem_subject":"transfer orbit","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"parking orbit","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spacecraft recovery","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"spare satellite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"velocity increment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"quasi-zenith satellite system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"satellite failure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"LEO","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"Parking orbit of a spare satellite and velocity increment to transfer to the operational orbit for quasi-zenith satellite system","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Parking orbit of a spare satellite and velocity increment to transfer to the operational orbit for quasi-zenith satellite system","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1559","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"7683","relation_version_is_last":true,"title":["Parking orbit of a spare satellite and velocity increment to transfer to the operational orbit for quasi-zenith satellite system"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:35:41.405008+00:00"}
