BD940

Advanced Multi-Constellation, Multi-Frequency Support

The Trimble® BD940 is a high-performance GNSS receiver module designed for precise positioning. It supports:

• Triple-frequency tracking from GPS and GLONASS
• Dual-frequency tracking from BeiDou and Galileo

As satellite constellations expand, the BD940 is ready to leverage additional signals—ensuring faster, more reliable RTK and RTX initializations for centimeter-level accuracy.

For applications not requiring RTK precision, the BD940 features an advanced Kalman filter PVT engine, delivering high-accuracy GNSS and DGNSS positioning even in challenging environments.

Flexible Configurations

Choose the configuration that fits your needs—from a basic autonomous GPS L1 unit to a full-featured, four-constellation, triple-frequency RTK solution.
All features are password-upgradeable, allowing you to scale functionality as your requirements evolve.

Safety-Critical Features

• Fault Detection and Exclusion (FDE)
• Receiver Autonomous Integrity Monitoring (RAIM)
  Ideal for applications where reliability and integrity are paramount.

Compact, Rugged Design

The BD940 is engineered for integration into space-constrained platforms:

• Dimensions: 51 mm x 41 mm x 7 mm
