An SPS collects solar energy in orbit and transmits the energy to various destinations. An SSPS is a total system that includes an SPS and ground facilities to utilize power from the SPS. JAXA is presently conducting system-level studies of a microwave-based SSPS (M-SSPS) and laser-based SSPS (L-SSPS). The M-SSPS is comprised of solar energy collection mirrors, power generators (PV arrays), and power transmitters (amplifiers and antennas). The size of the primary mirror will be 7 sq km, and the total mass will be 10 thousand tons to receive 1 gigawatt of electrical power on Earth. The other major SSPS concept is a laser-based system SSPS (L-SSPS), which uses a laser to transmit power. The M-SSPS requires the use of high voltage to transmit electrical power from the power generator (PV arrays) to the power transmitter to reduce the mass of cables and electrical loss at the cables. The power transmission tube (e.g., a magnetron) also must use high voltage. These high voltage devices may generate electrical charge and discharge. This is one of many technical challenges to be overcome before an SSPS is realized.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0049206004","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: JAXA-SP-05-001E","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-113X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11984031","subitem_source_identifier_type":"NCID"}]},"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"}]},"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"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小田, 光茂"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Oda, Mitsushige","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":"2020-01-16"}],"displaytype":"detail","filename":"49206004.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"49206004.pdf","url":"https://jaxa.repo.nii.ac.jp/record/6319/files/49206004.pdf"},"version_id":"27f63f3c-5153-40c6-a8af-79fa44087e47"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"宇宙機設計","subitem_subject_scheme":"Other"},{"subitem_subject":"太陽発電衛星","subitem_subject_scheme":"Other"},{"subitem_subject":"放電","subitem_subject_scheme":"Other"},{"subitem_subject":"マイクロ波送電","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙太陽発電システム","subitem_subject_scheme":"Other"},{"subitem_subject":"太陽放射","subitem_subject_scheme":"Other"},{"subitem_subject":"宇宙輸送システム","subitem_subject_scheme":"Other"},{"subitem_subject":"spacecraft design","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"solar power satellite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"electric discharge","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microwave power transmission","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Space Solar Power System","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"solar radiation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"space transportation system","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Solar Power Satellites and electrical charge/discharge","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Solar Power Satellites and electrical charge/discharge","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1066","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"6319","relation_version_is_last":true,"title":["Solar Power Satellites and electrical charge/discharge"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T07:57:56.412183+00:00"}
