GPS works fine in orbit. Several LEOs have carried GPS receivers.
It even works above the constellation to some extent, a capability proven by the experimental GPS receiver on AO-40 (one of the many scientific achievements credited to AMSAT satellites).

The BIRDS can do whatever is legal in their country and if they really wanted to make it unavailable while over the United States to appease the FCC, they can put an on/off switch based on GPS coordinates and then we would miss out on the fun of receiving the satellite.
How well does GPS work with satellites in LEO? (NavStars are in higher orbit, right?) Is it accurate? You'd have to sort of do a reverse bank shot thing because you're not dealing with the satellite's position, but the position of its footprint. How would that work? I see lots of math in someone's future! :-D
