We started to operate our new Australia Remote Observatory (ARO) where an 18 cm optical telescope with a charged-coupled device (CCD) camera covering a 3.17-degree field of view is used. We employ the horizontal coordinate system in which the stars move horizontally in an image, while GEO objects are relatively stationary. In our operation, the exposure time of light frame is set to be 3 seconds. In the uniform linear motion detection method, we select a sufficient number of object candidates (500 candidates in this paper) from each image based on their shape and intensity. Then we search a sequence of objects showing the uniform linear motion in the successive 18 images. As a result, we detected about 300 GEO objects up to magnitude of 15 among 5 night data. We also identified the objects from the two-line-element (TLE) data catalogue publicly provided by the U.S. Strategic Command (USSTRATCOM). We found that about one third of the detected objects are not listed in the catalogue. We conclude that our ARO and detection method posse a high efficiency detection of GEO objects despite the use of comparatively inexpensive observation and analysis system. We also describe the image-processing specialized for the detection of GEO objects (not for usual astronomical objects like stars) in this paper.\"","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AC1500076000","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: JSASS-2014-4643","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本航空宇宙学会(JSASS)"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Japan Society for Aeronautical and Space Sciences (JSASS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構(JAXA)"},{"subitem_text_value":"九州大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency(JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Kyushu University"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小田, 寛"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"柳沢, 俊史"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"黒崎, 裕久"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田川, 真"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oda, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yanagisawa, Toshifumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kurosaki, Hirohisa","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tagawa, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Space Debris","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"GEO","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Observation","subitem_subject_language":"en","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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"スペースデブリの光学観測、画像解析および検出手法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スペースデブリの光学観測、画像解析および検出手法"}]},"item_type_id":"5","owner":"1","path":["1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-10-30"},"publish_date":"2015-10-30","publish_status":"0","recid":"38716","relation_version_is_last":true,"title":["スペースデブリの光学観測、画像解析および検出手法"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T22:36:33.888442+00:00"}
