Triple frequency receiver with
integrated communications


Trimble BD930-UHF

The Trimble BD930-UHF supports both triple frequency from the GPS and GLONASS constellations plus dual frequency from BeiDou and Galileo. This compact board integrates the latest generation of UHF receiver modems allowing the system to instantly receive corrections from a large installed base of GNSS reference stations.

Trimble BD930-UHF

Key Features:

  • 220 Channels for multi-constellation GNSS support
  • EMI shielded module
  • Compact design for mobile applications
  • Integrated 403-473 MHz UHF receiver
  • Flexible RS232, USB and Ethernet interfacing
  • Centimeter level position accuracy



Trimble BD930-UHF

GNSS and communication tight integration

Taking advantage of Trimble’s expertize in both GNSS and UHF communications the Trimble® BD930-UHF module has been designed for applications requiring centimeter accuracy in a compact package. By integrating wireless communications on the same module the task of receiving RTK corrections is greatly simplifi ed. A single intuitive web interface allows a variety of use cases to be supported. Both GNSS and communication components are fully shielded. This design ensures the high quality signals are protected from the sources of EMI on the host platform. It also signifi cantly reduces radiated emissions which speeds compliance certifi cation and time to market.


Multi constellation GNSS

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 fi lter PVT engine that delivers high accuracy GNSS, DGNSS positions in the most challenging environments such as urban canyons. Diff erent confi gurations 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.

High performance integrated UHF receiver

Industry professionals trust Trimble embedded positioning technologies as the core of their precision applications. With the latest Trimble-precise Maxwell™ 6 technology, the BD930 provides assurance of long-term future-proofi ng and trouble-free operation. Moving the industry forward, the Trimble BD930 redefi nes high-performance positioning:

  • 70 MHz Bandwidth (403-473 MHz)
  • High Over-the-Air Link Rates
  • Industry standard link protocols


Flexible Interfacing

The Trimble BD930-UHF was designed for easy integration and rugged dependability. Customers benefi t from the Ethernet connectivity available on the board, allowing high speed data transfer and confi guration via standard web browsers. USB and RS-232 are also supported. Just like other Trimble embedded technologies, easy to use software commands simplify integration and reduce development times.
