It is an important milestone for the multi-billion-euro project to create a European version of the US Global Positioning System (GPS).

With four satellites now in orbit - the first and second spacecraft were launched in 2011 - it becomes possible to test Galileo end-to-end.

That is because a minimum of four satellites are required in the sky for a smartphone or vehicle to use their signals to calculate a positional fix.
