About the BD992-INS GNSS receiver module

The BD992-INS receiver module (also referred to as a receiver) contains a powerful multi-constellation, multi-frequency GNSS receiver with on-board integrated inertial sensors. Taking advantage of Trimble’s expertize in both GNSS and Inertial technology, the BD992-INS receiver 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. A simple intuitive web interface and interface protocol allows a variety of dynamic models to be supported.

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

The BD992-INS receiver module supports both the triple frequency for the GPS and GLONASS constellations, and the dual frequency from BeiDou and Galileo. As the number of satellites in the constellations grows, the receiver module is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK initializations for one- to two-centimeter positioning. For applications that do not require centimeter accuracy, the integrated GNSS-Inertial engine delivers high accuracy GNSS/DGNSS positions in the most challenging environments, such as urban canyons.

Different configurations are available. These include everything from a DGPS L1 unit through to a four-constellation triple-frequency RTK unit. Choose the configuration that suits your requirements. All features are password-upgradeable, allowing functionality to be upgraded as your requirements change.

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

Key features 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
