Plus there's the (already functioning) Russian GLONASS http://en.wikipedia.org/wiki/Glonass I think there are receiver chips that will work with both GPS and GLONASS, but they're not that common at the moment, presumably because they cost a few cents extra to manufacture. Perhaps the hype about GPS will encourage manufacturers to start building in this capability.
