The traffic capacity in Antarctica has increased rapidly due to the expansion of the station, increased members, substantial research items and establishment of advance stations. In the first decade, the A1 and A4 for PIX and FAX modulation system occupied the main stream of radio communication system between Syowa Station and Japan and the intra-Antarctic communications. But the increased traffic caused the shortage of circuit margin. The long distance bus link has to change the high speed PCM system through the geostationary satellites from HF link as if via Marisat. Much improvements are required in the following points : the intra-Antarctic system, the radiowave propagation between 300 and 500km, technical research on the local communication, and the data collection system of orbital satellites. The present situation and the future improvement of Antarctic communication are described in this paper.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00008460","subitem_identifier_reg_type":"JaLC"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00181831","subitem_source_identifier_type":"NCID"}]},"item_1_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00857289","subitem_source_identifier_type":"ISSN"}]},"item_1_subject_21":{"attribute_name":"国際十進分類法","attribute_value_mlt":[{"subitem_subject":"62(*2)","subitem_subject_scheme":"UDC"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Universityof Electro-Communications"},{"subitem_text_language":"en","subitem_text_value":"National Institute of Polar Research"}]},"item_1_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"電気通信大学"},{"subitem_text_value":"国立極地研究所"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1985-03-01"}],"displaytype":"detail","filename":"KJ00000139674.pdf","filesize":[{"value":"5.3 MB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000139674","url":"https://nipr.repo.nii.ac.jp/record/8460/files/KJ00000139674.pdf"},"version_id":"d2cd5a51-e753-4eca-8d3b-4d8ee07c56be"}]},"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":"南極通信の現状と将来計画","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南極通信の現状と将来計画"},{"subitem_title":"A present condition and future plan of communication network at Antarctica","subitem_title_language":"en"}]},"item_type_id":"1","owner":"4","path":["991"],"pubdate":{"attribute_name":"公開日","attribute_value":"1985-03-01"},"publish_date":"1985-03-01","publish_status":"0","recid":"8460","relation_version_is_last":true,"title":["南極通信の現状と将来計画"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T13:35:01.563950+00:00"}
