Trimble BD920


Dual frequency receiver speeds development
of mobile positionning applications

Trimble BD920

The Trimble BD920 is a small, dual frequency OEM GNSS receiver board that is capable of receiving a wide range of commercially available GNSS signals. It features centimeter-level, Real-Time Kinematic (RTK) positioning capabilities that are ideal for high-precision and control applications.

Key Features:

  • 220 Channels for multi-constellation GNSS support
  • Compact design for mobile applications
  • Fully EMI shielded module
  • Flexible RS232, USB and ethernet interfacing
  • Centimeter level position accuracy
  • Supports FDE and RAIM

Trimble BD920

Compact full metal jacket design

The Trimble® BD920 GNSS receiver module has been designed for applications requiring centimeter accuracy in a very small package. Mobile platforms can now embed proven Trimble RTK technology using a shielded module with a 51 mm x 41 mm x 7 mm form factor. The Trimble BD920 is a complete drop-in, solder-down module manufactured and tested to Trimble’s highest quality standards. This design ensures the high quality GNSS 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 BD920 supports both L1 and L2 frequencies from the GPS and GLONASS constellations plus the E1 frequency from Galileo. This delivers the quickest and most reliable RTK initializations for 1–2 centimeter positioning. For applications that do not require centimeter accuracy the BD920 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 including single frequency RTK and GPS only. All features are passwordupgradeable, 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.

Demonstrated performance

Industry professionals trust Trimble embedded positioning technologies as the core of their precision applications. With the latest Trimble-precise Maxwell™ 6 technology, the BD920 provides assurance of long-term future-proofi ng and trouble-free operation. Moving the industry forward, the Trimble BD920 redefi nes high-performance positioning:

  • On-board multipath mitigation
  • Proven low-elevation tracking technology

Flexible Interfacing

The Trimble BD920 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.
