Sirius 4 satellite now operational
Tuesday, January 29th, 2008
SES Sirius, an SES Astra company, announced today that the Sirius 4 communications satellite is now in operation and has taken over all transmissions from Sirius 2 and Sirius 3. Since it was launched on 18 November 2007, all operations have been carried out according to plan.
The Swedish Space Corporation is a minority shareholder in SES Sirius. Sirius 4 has now been installed at its final position, 4.8 degrees east. At the same time all channels from its sister satellites, Sirius 2 and Sirius 3, have been transferred to the new satellite. Sirius 4 is intended to meet the increased demand for HDTV broadcasts in the Nordic countries, and the needs arising from the large increase in new television channels within Eastern Europe.
Sirius 4 allows the commercialisation of 46 Ku band transponders in the Nordic region, the Baltic States, Central and Eastern Europe. This represents an increase of seven transponders for these regions after the switch from Sirius 2 and Sirius 3 to Sirius 4. Moreover the new satellite will make available another six additional transponders for the African market as well as Ka band capacity for interactive services in the Nordic and Baltic countries.
Sirius 4 is expected to be in operation for at least 15 years. As well as television broadcasts, it will also accommodate broadband communication. The new satellite covers virtually the whole of Europe, but the focus is on the Nordic region, the Baltic States and Central and Eastern Europe. Sirius 4 also has the capacity to reach southern Africa.
