Astra 1A was the first satellite launched and operated by SES (Société Européenne des Satellites), launched in December 1988. During its early days, it was often referred to as the Astra Satellite, as SES only operated one satellite originally. The satellite provided television coverage to Western Europe from 1989 through 2004 and was revolutionary as one of the first medium-powered satellites, allowing reception with smaller dishes than before. Astra 1A was retired and became in December 2004. ==Channels== Among the channels carried in the early years after launch were the entire four channel Sky Television (later British Sky Broadcasting. After the merger with rival British Satellite Broadcasting on the Marcopolo satellite), the services consisted of Sky One/Sky Channel, Sky News, Sky Movies and Eurosport, the Scandinavian TV3 and TV1000, the German Pro7, Sat.1, RTL plus, 3sat and Teleclub, the Dutch RTL4 as well as FilmNet, Screensport, MTV Europe, The Children's Channel and Lifestyle. Astra 1A began television broadcasts on February 5, 1989. Until 1998 all of SES' satellites were co-located with 1A at 19.2° east, leading that position to be known mostly as Astra 1 (later, Astra 19.2°E), although Astra 2C also used to operate there, before it moved to 28.2° east in autumn 2007. 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「Astra 1A」の詳細全文を読む スポンサード リンク
