In the case of the former, the time zone of position fixes varied with the time of the year and there were a little differences of the accuracies of position fixes except 3H (three-dimensional high level positioning). In the case of the latter, there were not obvious locality differences in 3D (three-dimensional positioning). But the positioning errors and number of data varied on each level in 2D (two-dimensional positioning), although the positioning errors were smaller than 0.1 nautical mile. The standard deviations of Dep. (departure) were larger than that of D.lat. (difference of latitude), and varied widely to the east and the west. But we observed that the standard deviations were smaller than 100 meters.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学水産学部研究報告, v.65, pp.45-53; 1989","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"38356","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Goda, Masaji"}]},{"nameIdentifiers":[{"nameIdentifier":"38357","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kuno, Toshiyuki"}]},{"nameIdentifiers":[{"nameIdentifier":"38358","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakane, Shigekatu"}]},{"nameIdentifiers":[{"nameIdentifier":"38359","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Jo, Eul Je"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学水産学部"}]},"item_3_relation_29":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40002770868","subitem_relation_type_select":"NAID"}}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178473","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05471427","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"合田, 政次"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"久野, 俊行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中根, 重勝"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"趙, 乙済"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"suisan65_045.pdf","filesize":[{"value":"593.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"suisan65_045.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/9498/files/suisan65_045.pdf"},"version_id":"a80ee3e8-a073-4bca-978c-80db8a7ec1b3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"GPS","subitem_subject_scheme":"Other"},{"subitem_subject":"global positioning system","subitem_subject_scheme":"Other"},{"subitem_subject":"測位精度","subitem_subject_scheme":"Other"},{"subitem_subject":"accuracy of position fixes","subitem_subject_scheme":"Other"},{"subitem_subject":"地域差","subitem_subject_scheme":"Other"},{"subitem_subject":"locality difference","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"GPSの測位精度-4 : 三定点における測定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"GPSの測位精度-4 : 三定点における測定"}]},"item_type_id":"3","owner":"2","path":["700"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-12-25"},"publish_date":"2012-12-25","publish_status":"0","recid":"9498","relation_version_is_last":true,"title":["GPSの測位精度-4 : 三定点における測定"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T01:44:31.007992+00:00"}
