Trimble BD940 GNSS Receiver

Triple Frequency Receiver with Integrated MSS Band Demodulator for Precise Positioning Applications.

This triple frequency receiver from Trimble delivers fast and reliable RTK and RTX initializations for centimeter positioning. The BD940 reduces radiated emissions which speeds compliance certification and time to market.

The BD940 GNSS receiver 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 tested to Trimble’s highest quality standards. Its design ensures the GNSS signals are protected from sources of EMI on the host platform. It also significantly reduces radiated emissions, which speeds compliance certification and time to market.

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 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 BD940 also supports Fault Detection and Exclusion (FDE) and Receiver Autonomous Integrity Monitoring (RAIM) for safety-critical applications.

ProPoint(TM) Engine

Trimble® ProPoint™ Positioning Engine

Trimble® ProPoint high-precision positioning engine provides position and orientation data from the fusion of (1) GNSS signals, (2) globally accessible high-accuracy correction services, and (3) measurement data from a variety of sensors. It leverages the latest in GNSS signal infrastructure and Trimble’s high-precision receiver hardware to deliver improved positioning performance in challenging environments. It also contains dynamic models of specific application movements allowing it to filter out unexpected dynamic movements, such as with a bulldozer sliding sideways during operation, for improved accuracy.

Improved RTK Accuracy
  • Improved RTK and Trimble RTX® performance in challenging environments where satellite line of sight can be impaired, such as under tree canopy, highway overpasses, and in dense urban areas.
  • Sensor Fusion using tighter integration of GNSS and IMU (and new technologies in the future) to provide continuous position and orientation solution.
  • Dynamic models tuned to specific applications such as automotive vs off-road vs marine for enhanced performance.
Increased Availability
  • Independent tracking loop to enable tracking of L2C, L5 signals in the solution if L1 is jammed.
  • Robust GNSS performance under harsh conditions such as canopy and urban environments.
  • Reduced convergence times (<1 min in RTX-Fast regions) by utilizing multi-constellation signals from GPS, Galileo, GLONASS, BeiDou and QZSS
Better Integrity
  • Advanced signal filtering and error modeling means better protection against jamming, spoofing and multipath interference.
  • Improved satellite health reporting to better handle unforeseen constellation outages.
  • Incorporation of Galileo NeQuick ionospheric model results in better resiliency.
Enhanced Constellation Support
  • Implementation of all open BeiDou3 signals in RTK and RTX solution.
  • Support for E6 data channel on Gen-II QZSS satellite signals.
  • NAVIC support for correction formats.
