The development of \"CubeSat\" is performed under the leadership of students and most parts of \"CubeSat\" are COTS (Commercial off-the-shelf) components. Using the large scientific balloon of ISAS, we conducted the long-range communication experiments and performance tests in the severe environment. The experiment  system in the balloon system was set in the same way as the actual CubeSat configuration. In this experiment, we could receive the house keeping data of satellite by the CW transmitter. The communication range is up to 450km. When the communications range is estimated more than 10km, commands were not received and we could not control the satellite by our FM uplink. When the communications range is estimated more than 40km, we could not receive the packet telemetry of satellite by FM transmitter. According to data from ISAS communication link, generation of a data packet and the data transmission to the transmitter in the set-up interval were operating normally, and we could reset the whole circuits by the ISAS command link. Thus, it turns out that a problem is transceiver itself. After the experiment, we conducted several environment tests and find the problems of communication system. We think the cause of these problems were malfunction of transceiver at low temperature, and radio frequency interference, Based on these experiment results, we developed a Cube Sat engineering model and a flight model.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0200104000","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":"東京工業大学"},{"subitem_text_value":"東京工業大学"},{"subitem_text_value":"東京工業大学"},{"subitem_text_value":"東京工業大学"},{"subitem_text_value":"東京工業大学"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Tokyo Institute of Technology"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岡田, 英人"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"澤田, 弘崇"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中谷, 幸司"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"占部, 智之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松永, 三郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okada, Hideto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sawada, Hirotaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nakaya, Koji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Urabe, Tomoyuki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Matsunaga, Saburo","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":"SA0200104.pdf","filesize":[{"value":"629.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0200104.pdf","url":"https://jaxa.repo.nii.ac.jp/record/33331/files/SA0200104.pdf"},"version_id":"6bf9bc91-5881-41a3-8ae7-1a5cfa12a2ec"}]},"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":"東工大CubeSat搭載用バス機器の機能評価実験","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"東工大CubeSat搭載用バス機器の機能評価実験"}]},"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":"33331","relation_version_is_last":true,"title":["東工大CubeSat搭載用バス機器の機能評価実験"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:09:56.591732+00:00"}
