Sirius 4 Satellite Now Operational

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.
SES ASTRA is an SES company (Paris:SESG) (LuxX:SESG). 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.

"The demand for HD channels will increase sharply in the years
ahead, and we operators need to be prepared in terms of capacity. An
HDTV broadcast requires 16 Mbit/s of bandwidth, compared with 4 Mbit/s
for a standard definition broadcast," says Hakan Sjodin, Managing
Director of SES SIRIUS.

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.

Sirius 4 was built by Lockheed Martin in California, where it was
also tested and subjected to extreme conditions similar to those
during launch and operation. The launch took place at the Baikonur
Cosmodrome in Kazakhstan, Central Asia. The satellite was carried by
an ILS Proton rocket that successfully launched the satellite into its
orbit, 36,000 km above the Earth´s surface. At that altitude, the
orbit period is 24 hours, which means that the satellites are
stationary in relation to the Earth. The satellite is controlled from
the Swedish Space Corporation´s satellite control station at Esrange
in Kiruna, which ensures that it maintains its position.
