Actually, IIRC more than half of the satellites are part of an Easter-bloc 
system controlled by Russia.

It is in the combining of these two incompatible systems that the 
less-than-one-meter accuracy is acheivable.

If the US shut ours down, the system would still work, but only to about 
10-meter granularity.

"AP - President Bush has ordered plans for temporarily disabling the U.S. 
network of global positioning satellites during a national
crisis to prevent terrorists from using the navigational technology, the White 
House said Wednesday. Full Story "

I hope the EU gets it's act together and launches their own band of GPS 
satellites soon. Of course, then will come the round of new
devices that attach to both networks? But it'll be worth it. 

I've always found it worrisome that what is becoming a key navigational 
technology worldwide is owned and controlled by the US
exclusively.And sure it's the right of the US to shut it down if it believes it 
is under threat, but given how things are going and
the reach of Executive power, I think having an alternative would be good for 
all us law abiding citizens that use the thing
everyday to get around and navigate or what have you.
