Many countries in these days try to build their own alternative to GPS, or in this example a extension for it. This for sure makes the location mor accurate and the systems are independant from the united states.
On the other hand for instance mobile phones have to implement all these systems and this makes them much more expensive and complicated. From my point of view it would be better to build up a universal international system. Yes, and I know this is nearly undoable.
