Goddard and Lt. Cmdr. Stephen H. Simpson, with some contributions from mobile radio pioneer Alfred J. Gross. It was reportedly named for Goddard's wife's Eleanor, and a WAC Major of Simpson's acquaintance named Joan.〔 The initial design work was performed at RCA's laboratories in Riverhead, NY, and the production units produced by Citizens Radio of Cleveland, Freed Radio Corporation of NYC, Dictagraph Corporation of New York, and the Signal-U Manufacturing Company. Most of the testing was carried out at in the USA and some at Bovington, England, beginning in July 1944, to refine the equipment with the first operational use later that same year. The system was classified as top secret by the US military and was not declassified until 1976. 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「Joan-Eleanor system」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.
