Transforming the way the world works


High performance integrated UHF receiver

The Trimble BD930-UHF supports both triple frequency from the GPS and GLONASS constellations plus dual frequency from BeiDou and Galileo. As the number of satellites in the constellations grows the BD930 is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK initializations for 1-2 centimeter positioning. For applications that do not require centimeter accuracy the BD930 contains an advanced kalman filter PVT engine that delivers high accuracy GNSS, DGNSS positions in the most challenging environments such as urban canyons.

Different configurations of the module are available. These include everything from a DGPS L1 unit all the way to a four constellation triple frequency RTK unit. Choose the receiver that suits your application and price point. All features are password upgradeable, allowing functionality to be upgraded as your requirements change. The receiver also supports Fault Detection and Exclusion (FDE) and Receiver. Autonomous Integrity Monitoring (RAIM) for safety-critical applications.
