You can do a GPS like system with what we have now. (x,y, and direction) What you need for location to be completely unabiguous is three sensors that can tell the direction to the the beacons relative to your robot's personal co-ordinate system. The sensors need to be arrainged so that they are never in a line with respect to both beacons. Though if you want to get fancy you can even accomodate that to some extent.

Only two sensors are required if you just want position and don't mind a little confusion when you cross the "equator" between the beacons.
