Several of you have mentioned the Russian GPS system
(Glonass) which has been in operation since the 1980's.
Several commercial (high-end) receivers work with both
GPS and Glonass. Google for details.

I borrowed one of Doug's (niceties.com) combined GPS
and Glonass Javad receivers in 2001 and here is a track
showing 10 GPS + 4 Glonass = 14 birds.
