At present, GPS is the nucleus of the navigation systems. Many new systems are being added to GPS in order to obtain higher accuracy and more complete integrity. The GPS system will thus be expanded and become more complex. The whole system is taking on an important role in the society and will become an indispensable infrastructure of the society. The present status GPS and Galileo are reviewed. Next, a study on the requirements for the system is described from the stand point of civil aviation, especially user requirements of strict accuracy and integrity. Frequency allocation, one of the system issues, is also discussed, because of the possibility of interference with other systems. Based on those inquires and studies, a prospective view and issues of the navigation satellite systems are investigated.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0033134000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NASDA-TMR-010020","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙開発事業団"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Space Development Agency of Japan (NASDA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1345-7888","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00364784","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙開発事業団 技術研究本部　先端ミッション研究センター"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Space Development Agency of Japan Advanced Mission Research Center, Office of Research and Development"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"稲宮, 健一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Inamiya, Kenichi","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":"2020-02-10"}],"displaytype":"detail","filename":"33134000.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"33134000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/42624/files/33134000.pdf"},"version_id":"abe3a04b-063c-4ed6-bb46-93f76a36825b"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"航行衛星システム","subitem_subject_scheme":"Other"},{"subitem_subject":"GPS","subitem_subject_scheme":"Other"},{"subitem_subject":"精度","subitem_subject_scheme":"Other"},{"subitem_subject":"サーベイ","subitem_subject_scheme":"Other"},{"subitem_subject":"Galileo宇宙機","subitem_subject_scheme":"Other"},{"subitem_subject":"民間航空","subitem_subject_scheme":"Other"},{"subitem_subject":"周波数割り当て","subitem_subject_scheme":"Other"},{"subitem_subject":"電磁干渉","subitem_subject_scheme":"Other"},{"subitem_subject":"navigation satellite system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"GPS","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"accuracy","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"survey","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Galileo spacecraft","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"civil aviation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"frequency assignment","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"electromagnetic interference","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"最近の航行衛星システムに関する調査研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"最近の航行衛星システムに関する調査研究"}]},"item_type_id":"3","owner":"1","path":["1893","1934"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"42624","relation_version_is_last":true,"title":["最近の航行衛星システムに関する調査研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T20:24:58.417459+00:00"}
