It seems they have differential GPS in lots of places now, like near
airports and sea-ports. For indoor use you would need differential GPS.
But for people who had that, it would make these robots really powerful.
And for a guy like me who lives on a tropical island, +/-100 feet is
plenty accurate enough for a solar powered robot boat to make it back to a
mile long beach.
