New EGNOS satellite
A Proton rocket has successfully launched the SES-5 telecommunications satellite - carrying a new EGNOS transponder.
The International Launch Services (ILS) Proton rocket was launched on 10 July from Russia’s Baikonur Cosmodrome in Kazakhstan.
The 6,007 kg SES-5 is reported to be healthy in orbit, with its solar panels deployed. Its final position will be in geostationary orbit at 5ºE.
In addition to the EGNOS payload, the satellite will carry up to 60 transponders for direct-to-home television, cellular and maritime communications in Europe, Africa and the Middle East.
The European Geostationary Navigation Overlay Service (EGNOS) provides augmentation for the GPS standard positioning service (SPS) - transmitted with the same frequency and modulation as GPS L1 (1575.42 MHz) and providing differential corrections and integrity information to improve navigation over Europe.
SES and the EC signed 2 contracts for EGNOS services in 2009 and 2010. The first is for SES-5, expected to last for the satellite’s full 15-year life. The second is for the Astra 5B spacecraft, to be positioned at 31.5ºE in mid-2013.
The commission is paying SES €9 (£7.1, $11.1) million per year, per satellite, for the service - a value of €270 million, assuming the satellites are retired after 15 years.
