The following points should be required in attaching an antenna pillar : (a) the pillar of a GPS antenna is tightly attached to the building by bolts, (b) the pillar can be installed anywhere practical and (c) the pillar is easy to set up. We devised three alternative methods that satisfy these points as follows : (1) installing a pillar made of stainless steel by anchor bolts in a flat place on the roof of the building, (2) a fixing an aluminum C channel of 1m length to the side wall of a building and attaching the pillar to the C channel by bolts, and (3) bolting the pillar to a stay made of 2-5 pieces of aluminum plate and fixed on the roof by bolts and cement. The method (3) provides us not only ease of installation but also a flexibility of adjustment of the antenna height depending on the condition of each site. For most of the possible cases such as on the parapet of a flat roof, on the surface of the eaves or on a side wall of a building, the GPS antenna can be installed by using one of the three proposed methods. Moreover, it was found that the construction costs may be minimized by favoring just one of them. We will try to improve these methods by carrying out test observations in the future.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"＜論説＞","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"72082","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HIRATA, Yasuhiro"}]},{"nameIdentifiers":[{"nameIdentifier":"72083","nameIdentifierScheme":"WEKO"}],"names":[{"name":"NAKAO, Shigeru"}]},{"nameIdentifiers":[{"nameIdentifier":"72084","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE, Shigeru"}]},{"nameIdentifiers":[{"nameIdentifier":"72085","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MORITA, Yuichi"}]}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00032264","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学地震研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1144042X","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13426486","subitem_source_identifier_type":"ISSN"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Earthquake Research Institute，University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学地震研究所地震地殻変動観測センター"},{"subitem_text_value":"地震地殻変動観測センター富士川地殻変動観測所"},{"subitem_text_value":"海半球観測研究センター"},{"subitem_text_value":"Earthquake Observation Center"},{"subitem_text_value":"Fujigawa Observatory, Earthquake Observation Center"},{"subitem_text_value":"Ocean Hemisphere Research Center, Earthquake Research Institute, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"平田, 安廣"}],"nameIdentifiers":[{"nameIdentifier":"72078","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中尾, 茂"}],"nameIdentifiers":[{"nameIdentifier":"72079","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡辺, 茂"}],"nameIdentifiers":[{"nameIdentifier":"72080","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森田, 裕一"}],"nameIdentifiers":[{"nameIdentifier":"72081","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":"2017-06-12"}],"displaytype":"detail","filename":"03_001-008.pdf","filesize":[{"value":"3.9MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"03_001-008.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/32273/files/03_001-008.pdf"},"version_id":"ab2fe5f0-81bd-4b59-85e0-b793470247f4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"setting method of antenna","subitem_subject_scheme":"Other"},{"subitem_subject":"portable L1 GPS system","subitem_subject_scheme":"Other"},{"subitem_subject":"crustal deformation","subitem_subject_scheme":"Other"},{"subitem_subject":"high density observation","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":"簡易1周波GPSシステムの試験観測におけるアンテナ設置","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"簡易1周波GPSシステムの試験観測におけるアンテナ設置","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"1","path":["4493","4494"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-05-15"},"publish_date":"2017-05-15","publish_status":"0","recid":"32273","relation_version_is_last":true,"title":["簡易1周波GPSシステムの試験観測におけるアンテナ設置"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-19T04:08:20.288526+00:00"}
