Description

Multi-Constellation / Multi-Frequency GNSS

The Trimble BD940 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 grow the BD940 is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK and RTX initializations for centimeter positioning.

For applications that do not require centimeter accuracy the BD940 contains an advanced Kalman filter PVT engine that delivers high accuracy GNSS, DGNSS positions in the most challenging environments.

Different configurations of the module are available. These include everything from an autonomous GPS 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.

Compact Full Metal Jacket

The Trimble BD940 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 BD940 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 significantly reduces radiated emissions which speeds compliance certification and time to market.

Trimble Maxwell™ 7 Technology

Industry professionals trust Trimble embedded positioning technologies as the core of their precision applications. With the latest Trimble Maxwell™ 7 Technology, the BD940 provides assurance of long-term future-proofing and trouble-free operation. Moving the industry forward, the Trimble BD940 redefines high-performance positioning:

336 Tracking Channels
Trimble Everest PlusTM multipath mitigation
Advanced RF Spectrum Monitoring and Analysis
Proven low-elevation tracking technology

Flexible Interfacing

The Trimble BD940 was designed for easy integration and rugged dependability. Customers benefit from the Ethernet connectivity available on the board, allowing high-speed data transfer and configuration 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.
