GPS on a mindstorm would rock completely, but
I'd recommend a compass for the following reason -
Civilian GPS is encrypted such that your position
is only guaranteed to within ~50-100m - fine for a
ship or hillwalker but not for an RCX attempting
to navigate a room! The error varies each time you
get a new position from GPS, so the RCX wouldn't even
be able to do relative positioning.
So unless you're willing to pay for differential GPS,
compass sounds better, especially if you had a bendy
robot trying to go round corners with a compass on
each end, 'cos then it could tell which way it was
oriented......
Not sure about cost of that, though......
