GNSS and inertial tight intergration


Taking advantage of Trimble’s expertize in both GNSS and Inertial technology the Trimble® BD940-INS module has been designed for applications requiring continuous centimeter accuracy in a compact package. By integrating inertial sensors on the same module, robust high accuracy positions are produced in all environments.

The GNSS components are fully shielded. This design ensures the high quality signals are protected from the sources of EMI on the host platform.

Multi constellation GNSS


The Trimble BD940-INS supports both triple frequency for the GPS and GLONASS constellations plus dual frequency from BeiDou and Galileo. As the number of satellites in the constellations grows the BD940-INS is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK initializations for 1–2 centimeter positioning. For applications that do not require centimeter accuracy the BD940-INS integrated GNSS Inertial engine 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 a DGPS 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.

With the option of utilizing OmniSTAR or RTX services, the BD940-INS delivers varying levels of performance down to centimeter-level without the use of a base station.

High performance integrated inertial sensors


The Trimble BD940-INS integrates the latest in precision inertial sensors in a compact package. With the BD940-INS you are buying a robust navigation solution, not just a GNSS receiver.
Key feature include :

  • High update rate position and orientation solutions
  • Continuous positioning in GNSS denied environments
  • Lever arm calculation from antenna to navigation point of interest
  • Robust Moving Baseline RTK for precision landing on moving platforms
  • Single antenna heading not influenced by magnetic field variations

Flexible Interfacing


The Trimble BD940-INS 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. An intuitive 3D interactive graphical web page allows easy input of lever arms. Dynamic and graphic models for various vehicle types can also be selected.
