翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Operation Phototrack ： ウィキペディア英語版 Operation Phototrack Operation Phototrack was among the programs quickly organized in the United States, after the Soviet earth satellite Sputnik 1 was launched on 4 October 1957, to fill the temporary tracking gap until the Baker-Nunn cameras specially designed to optically track U.S. satellites became operational. It was also referred to as the "Independent IGY (International Geophysical Year) Tracking Coordination Program". ==Use of volunteers== Supported by the Society of Photographic Scientists and Engineers (later the Society for Imaging Science and Technology), Phototrack enlisted volunteers who had wide-angle optical instruments with film-recording capability. Volunteers were recruited with announcements in various magazines and newspapers.〔"Sky and Telescope", Vol. XVII, No. 8, June 1958, in sidebar titled "Operation Phototrack" on p. 387 (Table of Contents page)〕〔"The Rotarian", Aug 1958, p. 34〕 Like its contemporary volunteer visual-tracking program called Moonwatch, it continued for some years as a supplement to the Baker-Nunn operation, since its results could fill in for the main system’s losses due to, for example, weather problems. Also like Moonwatch, some of its volunteers were located in countries outside the U. S,〔"List of Coordinates of Stations Engaged in the Observation of Artificial Earth Satellites", D.V. Mechau, Smithsonian Astrophysical Society, 1960〕 such as Canada,〔"Journal of the Royal Astronomical Society of Canada", 1961, p 236〕 Australia and Japan. 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「Operation Phototrack」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.
