Chinasat is a family of communications satellites operated by the China Direct Broadcast Satellite Company. The series was previously operated by the China Satellite Communications Corporation, and before that the China Telecommunications Broadcast Satellite Corporation, which was owned by China's Ministry of Post and Telecommunications.〔 (【引用サイトリンク】 Zhongxing / Chinasat )〕 Satellites formerly operated by the Sino Satellite Communications Company and the China Orient Telecommunications Satellite Company were renamed with Chinasat designations following their mergers with the China Satellite Communications Corporation to form China DBSAT. ChinaStar 1 became Chinasat 5A,〔(【引用サイトリンク】title=中星5A )〕 Sinosat-1 became Chinasat 5B,〔(【引用サイトリンク】title=中星5B )〕 and Sinosat-3 became Chinasat 5C.〔(【引用サイトリンク】title=中星5C )〕 == Chinasat 6B == The Chinasat 6B satellite was manufactured by Thales Alenia Space. It has 38 transponders, and is being used for TV transmissions and shortwave jamming across China, Southeast Asia, the Pacific and Oceania. It has a planned useful life of 15 years.〔 〕 Thales Alenia Space built the satellite with no components from the United States whatsoever. This allowed it to be launched on a Chinese launch vehicle without violating U.S. ITAR restrictions.〔 〕 The launch, on a Long March 3B rocket, was successfully conducted on 5 July 2007. The broadcast used for some shortwave radio jamming purposes in China is carried on one of the Chinasat 6B transponders.〔(【引用サイトリンク】title=Firedrake - The source of China's Radio Jammer found on Chinasat 6B )〕 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「Chinasat」の詳細全文を読む スポンサード リンク
