It was built to support the space missions of the Soviet Union. Similar networks are run by the USA, China, Europe, Japan, and India. == History == The first Soviet space network had 13 stations and was designed to track Earth orbiting satellites.〔Don P. Mitchel. (Soviet Telemetry Systems. Deep-Space Communication Centers. )〕 Interplanetary missions require larger antennas, more powerful transmitters, and more sensitive receivers, and this effort was started in 1959 to support the planned 1960 launch of the Venera series of missions to Venus and the Mars program of spacecraft to Mars. The selected design consisted of eight 16-meter dishes placed on two hulls of diesel submarines, welded together and laid down on the railway bridge trusses. These trusses were mounted on bearings from battleship gun turrets.〔 Three such antennas were built: the two North stations for receiving, and the south station a few kilometers away for transmitting. In 1978, these antennas were augmented by the 70-meter antennas at Yevpatoria and Ussuriisk, with a third that was never completed at Suffa, Uzbekistan. 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「Soviet Deep Space Network」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.
