Dual-antenna input
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.
Trimble Maxwell 7 Technology
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 Maxwell™ 7 Technology, the
BD992 provides :
- 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 BD992 delivers varying levels of
performance down to centimeter-level without
the use of a base station.
Robust centimeter accurate solutions
The Trimble BD992 integrates the latest in
precision inertial sensors in a compact package.
With the BD992 you are buying a robust
navigation solution, not just a GNSS receiver.
Key features include:
- High update rate position and heading solutions
- Robust Moving Baseline RTK for precision on moving platforms
Flexible interfacing
The Trimble BD992 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
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.
