In particular, ionospheric scintillation may cause GPS satellite signal loss, and multiple losses can degrade the availability of positioning/navigation services such as GBAS (Ground-Based Augmentation Systems). In order to improve the tracking performance of GPS receivers under scintillation conditions, an ultra-tightly coupled GPS/INS (Inertial Navigation System) integrated system has been developed and flight tests to evaluate it were conducted around the island of Ishigaki where ionosphere scintillation frequently occurs. Evaluation of phase tracking performance was carried out off-line using a software-defined GPS receiver which processes stored IF (Intermediate Frequency) data. The use of INS enabled a longer integration time of GPS signals, which increased the signal-to-noise ratio (SNR). As a result, the tracking loop of GPS/INS achieved continuous phase tracking even under strong scintillation conditions.","subitem_description_type":"Other"}]},"item_7_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_7_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_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1520040000","subitem_description_type":"Other"}]},"item_7_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"システム制御情報学会"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Institute of Systems, Control and Information Engineers"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.5687/iscie.27.476"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.5687/iscie.27.476","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1342-5668","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN1013280X","subitem_source_identifier_type":"NCID"}]},"item_7_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構航空本部（JAXA）"},{"subitem_text_value":"宇宙航空研究開発機構航空本部（JAXA）"},{"subitem_text_value":"多摩川精機株式会社"},{"subitem_text_value":"立命館大学"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Tamagawa Seiki Co., Ltd."},{"subitem_text_language":"en","subitem_text_value":"Ritsumeikan University"}]},"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":"辻井, 利昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"藤原, 健"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"久保田, 鉄也"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"久保, 幸弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tsujii, Toshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Fujiwara, Takeshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kubota, Tetsunari","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kubo, Yukihiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"doppler assist","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"coherent integration","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"equatorial plasma bubble","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"flight evaluation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"robust tracking","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Testing of an Ultra-tightly coupled GPS/INS under Strong Ionospheric Scintillation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Testing of an Ultra-tightly coupled GPS/INS under Strong Ionospheric Scintillation","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-08-17"},"publish_date":"2015-08-17","publish_status":"0","recid":"22625","relation_version_is_last":true,"title":["Testing of an Ultra-tightly coupled GPS/INS under Strong Ionospheric Scintillation"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:18:00.990571+00:00"}
