Just to give some figures: GPS will give you 5 to 30 meters accuracy
(as long as the US lets you have it). Galileo will give you about the
same accuracy. I suppose the US can jam both. I'd guess if they could
not, they would not have increased the accuracy publicly available and
would make much more of a fuss about Galileo.

I doubt that US can jam Galileo just by turning a switch as it it with GPS.
But they probably will develop some jamming feature against the Galileos
signals.


I heared that turning back on selective availability is not much of an
option anymore because the economic aplications that depend on it are
too valuable to lose and that the SA cannot be targeted in a small
enough area.
