The purpose is to measure the angle between rocket spin axis and geomagnetic field vector. The Z-axis of the magnetic sensor was parallel to the spin axis and the other two magnetic sensor (X-axis and Y-axis) located on a plane perpendicular to the spin axis. The magnetic sensors were located by a rigid boom of 18cm in length in order to reduce the magnetic disturbance from the rocket body and the payload instruments. The range of measurable magnetic field was-50000nT to +50000nT and the resolution was 1.6nT. The sampling time was 10ms and the noise level was less than 5nT. The magnetic bias was 980nT in the rocket at the sensor position. The magnetometer was completely operated during the flight and it provided us satisfactory geomagnetic field data. The magnetic attitude of the rocket was determined using magnetometer. The spin rate of rocket was 0.83Hz and the coning half angle of the precession was 10° with the period of 192 seconds.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0167129000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_9_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0285-9920","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00354485","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東海大学"},{"subitem_text_value":"東海大学"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"高橋, 隆男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"遠山, 文雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAHASI, Takao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TOHYAMA, Fumio","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-24"}],"displaytype":"detail","filename":"SA0167129.pdf","filesize":[{"value":"228.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0167129.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33205/files/SA0167129.pdf"},"version_id":"081cbff2-d269-4642-956c-783ece125842"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"地球磁場","subitem_subject_scheme":"Other"},{"subitem_subject":"高感度磁力計","subitem_subject_scheme":"Other"},{"subitem_subject":"飛翔姿勢","subitem_subject_scheme":"Other"},{"subitem_subject":"地磁気姿勢角","subitem_subject_scheme":"Other"},{"subitem_subject":"スピン特性","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":"高感度磁力計 (MGF) による磁場観測","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高感度磁力計 (MGF) による磁場観測"}]},"item_type_id":"9","owner":"1","path":["1890","1912"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"33205","relation_version_is_last":true,"title":["高感度磁力計 (MGF) による磁場観測"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:12:55.539835+00:00"}
