Galileo is a reality.
The first two satellites of the constellation were launched by the first Soyuz from French Guyane last October. Since then they have transmitted the first Galileo signals that will carry the different services to be provided by the global European navigation system. Currently these In Orbit Validation Satellites are being tested, calibrated, in particular from the ground station of Redu, Belgium.
