Trimble BD990

The Trimble BD990 supports triple frequency for the GPS, GLONASS, BeiDou and Galileo constellations. As the number of satellites in the constellations grows the BD990 is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK initializations for centimeter positioning. With the option of utilizing OmniSTAR or RTX services, the BD990 delivers varying levels of performance down to centimeter-level without the use of a base station.
