The 9205-GNSS is a legacy combined position and correction receiver which can use the GPS, GLONASS, Galileo and BeiDou constellations with a (chargeable) software unlock, significantly increasing the number of satellites available for a position solution. NOTE: The 9205 is out of production and although it is still supported users should consider upgrading to the current direct replacement, the Fugro 9410-AUT.
