BD930-UHF GNSS Receiver Board

Manufacturer: | Categories: ,

The BD930-UHF from Trimble is at End of Life (EOL). Please contact us to determine the best replacement product for your application.



The BD930-UHF GNSS receiver board from Trimble is a compact board with the latest UHF receiver modems integrated to receive corrections from a huge installed base of GNSS reference stations instantly. It caters for dual frequency from both the Galileo and BeiDou constellations, as well as triple frequency from the GPS and GLONASS constellations.

With the BD930-UHF GNSS receiver board, receiving RTK corrections has been made simple by integrating GNSS and UHF communications on the same board. This compact package delivers centimeter accuracy and its communication components are fully shielded to protect the signals from EMI interference.

Although it can easily handle 1–2 centimeter positioning with reliable RTK initializations, the Trimble BD930-UHF also uses an advanced kalman filter PVT engine that can deliver high accuracy GNSS, DGNSS positions in challenging environments, albeit at less than centimeter accuracy. Triple frequency from the GPS and GLONASS constellations are supported, as well as dual frequency from BeiDou and Galileo.

The BD930-UHF module is available in different configurations to suits your application and price point. Choose a DGPS L1 unit, or select the four constellation triple frequency RTK unit. As the features are password-upgradeable, you will never outgrow the functionality, but can simply upgrade when needed.

If you need Fault Detection and Exclusion (FDE), or Receiver Autonomous Integrity Monitoring (RAIM) for safety-critical applications, these features are also available.

Easy integration is made possible through the Ethernet, USB and RS-232 ports, while software commands reduce development times.
