SES was named ‘Satellite Operator of the Year’ by consultancy and research organisation Euroconsult, in 2007 and in 2015. == Innovations == SES is one of the global market leaders of satellite communications services and a pioneer in many important industry developments. SES pioneered DTH transmission, co-location of satellites, free-to-air broadcast neighbourhoods, digital broadcasting, HDTV〔''High Above – The untold story of Astra, Europe’s leading satellite company'' Broadgate Publications April 2010〕 and 3DTV.〔(【引用サイトリンク】title=SES WORLD SKIES To Host Extensive 3D TV Tests )〕 SES has also helped develop innovative reception technology such as the first home dish LNBFs, Universal LNBs, optical fibre signal distribution and the SAT>IP system for receiving and distributing satellite signals over home computer networks. SES is currently pioneering the broadcast of next generation Ultra High Definition TV (UHD) and helping to establish the international technical standards for UHD broadcast and reception. SES first produced demonstration UHD broadcasts in 2012 and transmitted the first HEVC-standard UHD TV in 2013. A continuous SES UHD demonstration channel is broadcast to Europe from SES’ Astra 19.2°E satellite position and Europe's first free-to-air Ultra HD channel will launch in September 2015, broadcast via Astra 19.2°E. SES is also an innovator in satellite and launcher technology. Launched in 2013, SES-8 was the first geostationary satellite to be launched by privately funded company, SpaceX, which has revolutionised the costs of satellite launches.〔(''Creating Space - The Satellite Revolution'' ) SES white paper. March 2015. Retrieved May 27, 2015〕 The SES-12, SES-14 and SES-15 satellites (due for launch in 2017) are being constructed with an electric plasma propulsion system for orbit raising and in-orbit manoeuvres to save weight and enable a larger communications payload to be included. SES reckons that SES-12 would weigh some 4700 kg more with a conventional chemical propulsion system.〔 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「SES S.A.」の詳細全文を読む スポンサード リンク
