First the present condition and the principle of satellite navigation are described, and navigation method and its precision are studied analytically and formulated. After that, following studies are conducted: varieties of typical satellite constellations samples and their tradeoffs, relation between the constellations and navigation accuracy, ground station support to enhance the precision, and intelligent user terminals. Following items are also studied: coexistence of the navigation method based on clock synchronization and asynchronous navigation method such as GPS, and navigation method based on the weighting coefficients variable least-squares method. From the algorithm, DOP (Dilution of Precision) is determined, which expresses generally the precision of various navigation method.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0000268000","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-960001","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　システム技術研究部"}]},"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 Systems Engineering Department, Office of Research and Development"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山脇, 功次"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamawaki, Koji","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":"00268000.pdf","filesize":[{"value":"12.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"00268000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/39706/files/00268000.pdf"},"version_id":"3decc164-aa0f-41ed-983f-d576f07954e8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"測位システム","subitem_subject_scheme":"Other"},{"subitem_subject":"GPS","subitem_subject_scheme":"Other"},{"subitem_subject":"全地球的位置決定システム","subitem_subject_scheme":"Other"},{"subitem_subject":"システム解析","subitem_subject_scheme":"Other"},{"subitem_subject":"クロック同期型測位方式","subitem_subject_scheme":"Other"},{"subitem_subject":"精度","subitem_subject_scheme":"Other"},{"subitem_subject":"アルゴリズム","subitem_subject_scheme":"Other"},{"subitem_subject":"最小自乗測位方式","subitem_subject_scheme":"Other"},{"subitem_subject":"衛星航法","subitem_subject_scheme":"Other"},{"subitem_subject":"衛星配置","subitem_subject_scheme":"Other"},{"subitem_subject":"非同期型測位方式","subitem_subject_scheme":"Other"},{"subitem_subject":"測位劣化指数","subitem_subject_scheme":"Other"},{"subitem_subject":"navigation system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"GPS","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"global positioning system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"system analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"clock synchronous navigation system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"precision","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"algorithm","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"navigation method based on least squares","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"satellite based navigation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"satellite constellation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"asynchronous navigation system","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"dilution of precision","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":"衛星航法の基礎理論とその応用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"衛星航法の基礎理論とその応用"}]},"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":"39706","relation_version_is_last":true,"title":["衛星航法の基礎理論とその応用"],"weko_creator_id":"1","weko_shared_id":1},"updated":"2023-06-20T19:17:04.972394+00:00"}
