1.I know of no reason why Galileo should be superior to GPS,and anyrate it doesn't exist yet (just two demonstrators, the cheaper of which was from a UK university and saved the dayfrom losing frquency allocation to comms industry)
First Gallileo satellite was
not made by a UK university. It was made by a spin-off company of a UK university
Surrey Satellite Technology Ltd (SSTL) - Home . The company was created in the 80s and was bought recently by EADS Astrium.
If the link doesn't convince you PM me for more.
Again, Gallileo its not about making a superior system (at least at first) but about strategic independence...
