PCSAT carried one of the first GPS's to obit in 2001. Maybe sometime during its next good power period, I should turn it on... hummh...

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).

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
