The navigator asked for the answer into the\nmovement of heavenly bodies. The moon travels about 0.55 degree per hour, roughly\nequivalent to its own apparent diameter, against the celestial coordinate. Consequently,\nthe angle between the moon and other celestial bodies, the angles called “the Lunar\nDistance”, changes from moment to moment. It can determine the time by measuring the\nLunar Distance and comparing the distance with forecasted values on the almanac.\nHowever, to measure the Lunar Distance by sextant on the ship is very difficult, good\nresults have not been raised with the classical Lunar Distance method.\nIn this paper, in order to overcome the difficulty of measuring the Lunar Distance, we\nshowed the method which is able to measure the Lunar Distance indirectly. We actually\nperformed the indirect measuring method on the ocean voyage and show some results","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15053/0000000200","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"海上保安大学校"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.15053/2012.21.02","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10088865","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0287-2951","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"田中, 隆博"},{"creatorName":"タナカ, タカヒロ","creatorNameLang":"ja-Kana"},{"creatorName":"TANAKA, Takahiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"50","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 拓司"},{"creatorName":"コバヤシ, タクジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"388","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"島村, 圭一"},{"creatorName":"シマムラ, ケイイチ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"389","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"KOBAYASHI, Takuji","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"390","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"SHIMAMURA, Keiichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"391","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-05-31"}],"displaytype":"detail","filename":"2_56-1-78-02_Tanaka.pdf","filesize":[{"value":"632.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"月距法による時刻推定","url":"https://jcga.repo.nii.ac.jp/record/200/files/2_56-1-78-02_Tanaka.pdf"},"version_id":"14c26754-be35-4c42-98f8-565e7443978d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Lunar Distance Method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Celestial Navigation","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"月距法による時刻推定 - 間接測定による方法の実海域での検証 -","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"月距法による時刻推定 - 間接測定による方法の実海域での検証 -","subitem_title_language":"ja"},{"subitem_title":"Time Determination by Lunar Distance Method - Indirect Measuring of Lunar Distance and Verification on Actual Ocean Voyage -","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"5","path":["50"],"pubdate":{"attribute_name":"公開日","attribute_value":"2023-05-31"},"publish_date":"2023-05-31","publish_status":"0","recid":"200","relation_version_is_last":true,"title":["月距法による時刻推定 - 間接測定による方法の実海域での検証 -"],"weko_creator_id":"5","weko_shared_id":-1},"updated":"2023-10-05T23:05:09.734838+00:00"}
