Fugro introduces the introduction of a new satellite based precise positioning service: G2. This new high performance navigation service combines the navigation satellites of both the American GPS constellation and the Russian GLONASS constellation, to produce a composite GPS/GLONASS position solution. The service utilises Fugro’s own network of dual system reference stations to calculate ‘orbit and clock’ errors on a satellite by satellite basis for all 50 satellites of the two global navigation satellite systems thus providing consistent decimetre level accuracy positioning on a world wide basis….more at Fugro.com
