I wonder why this comment got so many downvotes. I also disagree with the description of the system being a GPS. Relating local positions to your surroundings might provide you with a relatively accurate position from a world-perspective depending on your mind, but it's not "hey - we've got these N external positioning inputs and we can calculate our position using them."
