The in-orbit validation of Galileo has been achieved [gpsworld.com], according to the European Space Agency (ESA). Europe now has the operational nucleus of its own satellite navigation constellation in place — the world's first civil-owned and operated satnav system.

Galileo's observed dual-frequency positioning accuracy is an average of 8 meters horizontal and 9 meters vertical, 95 percent of the time. Its average timing accuracy is 10 billionths of a second. Its performance is expected to improve as more satellites are launched and ground stations come on line.
