From the analysis of positioning data of about 10000 passes over 245 days, it is clearly found that the position determination error increases with increasing geomagnetic disturbance level (local K-index) and the number of passes on which the position determination is succeeded decreases by one or two per day when K-index is large. These results suggest that when the ionosphere is highly disturbed the 150 and 400MHz radio waves from the satellites are strongly scattered by ionospheric irregularities and/or spatial gradients of the electron density associated with ionospheric disturbances.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004049","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10756224","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Radio Research Laboratory/Radio Research Laboratory/Radio Research Laboratory/Radio Research Laboratory"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1988-02-01"}],"displaytype":"detail","filename":"KJ00000035895.pdf","filesize":[{"value":"583.2 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00000035895","url":"https://nipr.repo.nii.ac.jp/record/4049/files/KJ00000035895.pdf"},"version_id":"3d9ea8dd-6335-469f-8681-9c3a17987a0f"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Ionospheric disturbance effect on NNSS satellite positionings at Syowa Station","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Ionospheric disturbance effect on NNSS satellite positionings at Syowa Station"}]},"item_type_id":"1","owner":"4","path":["537"],"pubdate":{"attribute_name":"公開日","attribute_value":"1988-02-01"},"publish_date":"1988-02-01","publish_status":"0","recid":"4049","relation_version_is_last":true,"title":["Ionospheric disturbance effect on NNSS satellite positionings at Syowa Station"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:24:29.639822+00:00"}
