Re: Spexit!
Well, you see, I have done a course on orbital mechanics. And I also have access to powerful internet search technology, and I found this. And, oh look, the orbital eccentricity is ... zero: they're fucking circular orbits. And just to complete it: they're all in orbits at 56 degrees inclination, three groups of 10 (8 active, two spare) separated by 120 degrees.
GPS works at 55 degrees inclination (so, the same) with six groups separated by 60 degrees, four satellites per plane.
This is not a system which 'favours Europe': please quit your dissimulation.
