About the BD940 GNSS receiver module

The Trimble BD940 receiver module (also referred to as a receiver) is a powerful multi-constellation, multi-frequency GNSS receiver that provides very precise continuous positioning by leveraging the power of the Maxwell™ 7 processing technology. The GNSS receiver supports triple frequency from both GPS and GLONASS constellations plus dual-frequency from BeiDou and Galileo.

As the numbers of satellites in the constellations grow, the BD940 receiver module is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK initializations for centimeter positioning. For applications that do not require centimeter-level accuracy, the BD940 contains an advanced Kalman filter PVT engine that delivers high accuracy GNSS/DGNSS positions in the most challenging environments such as urban canyons.

Different configurations of the module are available. These include everything from an autonomous GPS L1 unit to a four-constellation triple-frequency RTK unit. This gives the flexibility for the end user to choose a module that best fits their application and price point.

With the latest Trimble Maxwell 7 technology, the BD940 receiver module provides assurance of long-term future-proofing and trouble-free operation. Moving the industry forward, the BD940 receiver module redefines high-performance positioning.

A variety of streamed outputs are supported. These outputs provide detailed information, including the time, position, heading, quality assurance (figure of merit) numbers, and the number of tracked satellites. The receiver also outputs a one pulse per second (1PPS) strobe signal, which lets remote devices precisely synchronize time.

Designed for reliable operation in all environments, the receiver provides a positioning interface to an office computer, external processing device, or control system.
