GPS is the U.S military version of a GNSS which also gives them full control over it. I can understand if there are many countries that are happier to rely on older technologies over which they have full control.
But a good thing for the rest of the world is that GALILEO will be up and running from 2008, which is much more suited for civilian applications and not controled by the military or a single country. As they say on their website: "A system that both competes with and complements the American GPS system".
One of the features is that it is sending an "integrity message" informing the user immediately of any errors. Nice to have on a future GNSS precision approach to the hover, don't you think?
