翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Dove-OSCAR 17 ： ウィキペディア英語版 Dove-OSCAR 17 Dove-OSCAR 17 (aka DO-17 or Microsat 2) is a Brazilian educational and amateur radio satellite launched at January 22, 1990. ==Project== Dove-OSCAR 17 is one the results of the so called Microsat project by AMSAT, manufactured in the 1980s by the civil and electric engineer Junior Torres de Castro (amateur radio operator with callsign PY2BJO), who had been developing his ideas since 1957. He has built, with his own resources, the first artificial satellite for educational and humanitarian purposes: the "Dove". The device, assembled in a garage in São Paulo, was meant to provide synthesised peace messages for educational institutions at a time when the Cold War was still determining international relations around the world. It has a Digital Orbiting Voice Encoder (D.O.V.E.), designed to emit the synthesised voice messages, and also telemetry data transmission (FM Packet AFSK 1200 AX.25 at 145.825 MHz). It is box shaped with dimensions of 213 × 230 × 230 mm, with solar panels on the faces of the cube and weights 12.92 kg.〔(【引用サイトリンク】url=http://space.skyrocket.de/doc_sdat/dove.htm )〕 The configuration and assembly was at that time designated as "Microsat". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dove-OSCAR 17」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
