BD992 Receiver Module

Dual-antenna receiver delivers centimeter accurate positions and precise heading

The Trimble BD992 GNSS system is a single-board solution for precise position and heading. Single-antenna GNSS systems have difficulty determining where the antenna is positioned relative to the vehicle and object of interest, especially when dynamics are low. External sensors can be used to augment this however these tend to drift when static. Heading derived from dual-antenna GNSS measurements overcomes these issues and is now economically the right choice.

Description

The Trimble BD992 supports triple-frequency for the GPS, GLONASS, BeiDou and Galileo constellations. As the number of satellites in the constellations grows the BD992 is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK initializations for centimeter positioning. With the latest Trimble MaxwellTM 7 Technology, the BD992 provides:

336 Tracking Channels
Trimble Everest PlusTM multipath mitigation
Advanced RF Spectrum Monitoring and Analysis
Proven low-elevation tracking technology

With the option of utilizing OmniSTAR or RTX services, the BD992 delivers varying levels of performance down to centimeter-level without the use of a base station.
