The onboard atomic clocks that drive the satellite-navigation signals on Europe's Galileo network have been failing at an alarming rate. Across the 18 satellites now in orbit, nine clocks have stopped operating. Three are traditional rubidium devices; six are the more precise hydrogen maser instruments that were designed to give Galileo superior performance to the American GPS network. Read more
EU's Galileo satellite system goes live after 17 years
The EU's Galileo satellite system has gone live, aiming to supply the world's most accurate satellite navigation technology. It follows 17 years of development, plagued by delays and budget increases. The 18 satellites initially launched will be of only limited use at first for smartphones and in-car systems. Read more
Europe's new age of satellite navigation has passed a historic milestone - the very first determination of a ground location using the four Galileo satellites currently in orbit together with their ground facilities. This fundamental step confirms the Galileo system works as planned. Read more
The Launch Readiness Review (RAL) took place in Kourou on Thursday October 11, 2012 and authorised count-down operations for the Soyuz ST-b - GALILEO IOV-2 FM3 & FM4 launch. For its third Soyuz launch from the Guiana Space Centre in French Guiana, Arianespace will place two new satellites of the Galileo constellation into circular orbit at 23,000 km, as part of the IOV (In Orbit Validation) program. With the successful Soyuz launch from the Guiana Space Centre, along with Ariane 5 and Vega, Arianespace is now the only launch services provider in the world capable of launching all types of payloads to all orbits, from the smallest to the largest geostationary satellites, along with clusters of satellites for constellations and missions to support the International Space Station. The launch will be from the Soyuz Launch Complex (ELS) in Sinnamary, French Guiana.
Liftoff is scheduled for Friday, October 12, at exactly:
03:15:01 pm local time in French Guiana 18:15:01 in UTC 02:15:01 pm in Washington, D.C. 08:15:01 pm in Paris 10:15:01 pm in Moscow.
