Sirius 1 was moved to 13° west and renamed Sirius W in 2000 and retired in 2003. Tele-X was retired to a graveyard orbit in 1998. Sirius 1 was later joined at 5° east by Sirius 2 (1997) and then Sirius 3 (1998), with the most recent addition, Sirius 4, launched in November 2007. In 1994, Tele-X was joined by Sirius 1, bought by NSAB from BSkyB in 1993 after Sky Television's merger with British Satellite Broadcasting, and moved to 5☎ from its original orbital position at 30°West as Marcopolo 1. The Astra 5☎ orbital position was originally the Direct broadcast satellite orbital position allocated to Sweden with Swedish Satellite Corporation's Tele-X (launched 1989) the first TV satellite at this position. Capacity and reach Īs of December 2019 the Astra satellites at 5° east broadcast on 121 transponders (28 C-Band, 3 Ka-band and 90 Ku-band) to 51.5 million households (34.1 million via cable, 10.7 million via IPTV and 6.7 million direct to home satellite dishes). SES-5 also carries a hosted L-band payload for the European Commission's European Geostationary Navigation Overlay Service (EGNOS). It also has C-band capacity on a global coverage beam and a hemispheric coverage for Europe, Africa and the Middle East to deliver broadband, maritime communications, GSM backhaul, and VSAT applications. SES-5 provides two Ku-band beams for DTH services, one for the Nordic and Baltic countries and one serving Sub-Saharan Africa. This position also provides uplink and downlink within the African footprint, and inter-connectivity between Africa and Europe, so that DTH broadcasting out of Europe is available without the need for expensive fibre links. Cable distribution to head-ends, contribution links, data services, and broadband capacity are also providedĪstra 4A provides DTH coverage to multiple African markets with a dedicated K u band beam from a single orbital position, which eliminates the need for dual-illumination from separate beams. Over 460 TV, radio and interactive channels (including 9 high-definition television stations serve over 21 millionĭirect-to-home, SMATV and cable homes via the 5☎ position. Sirius 2/Astra 5A (operated by NSAB - failed in orbit)Īstra 5☎ is SES' position for direct-to-home (DTH) broadcasting to Sweden, Denmark, Norway and Finland, as well as Eastern European and Baltic countries including Belarus, Bulgaria, Estonia, Latvia, Lithuania, Romania, Russia, and Ukraine, and sub-Saharan Africa.
