GNSS and inertial tight integration

Taking advantage of Trimble’s expertize in both GNSS and Inertial technology the Trimble® BX992 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 and orientations are produced in all environments.

Trimble Maxwell 7 Technology

The Trimble BX992 supports triple frequency for the GPS, GLONASS, BeiDou and Galileo constellations. As the number of satellites in the constellations grows the BX992 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 accuracy the BX992 integrated GNSS-Inertial engine also delivers high accuracy GNSS, DGNSS positions in the most challenging environments such as urban canyons. With the latest Trimble Maxwell™ 7 Technology, the BX992 provides:

  • 2 x 336 Tracking Channels
  • Trimble Everest Plus multipath mitigation
  • Advanced RF Spectrum Monitoring and Analysis
  • Proven low-elevation tracking technology

With the option of utilizing OmniSTAR or RTX services, the BX992 delivers varying levels of performance down to centimeter-level without the use of a base station.

Robust centimeter accurate solutions

The Trimble BX992 integrates the latest in precision inertial sensors in a compact package. With the BX992 you are buying a robust navigation solution, not just a GNSS receiver.
Key features include:

  • High update rate position and orientation solutions
  • Dual antenna for rapid heading alignment
  • 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

Flexible Interfacing

The Trimble BX992 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, CAN 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.

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. All features are password-upgradeable, allowing functionality to be upgraded as your requirements change.
