I forget the figures, but GPS will not locate your position to
anything near the resolution needed for traditional VR - i.e. it could
maybe say which room you're in in a building, but it wouldn't tell you
where you are in the room.  My understanding is that the military have
much higher resolution systems, but we (the general public) cannot
access them.
