Triple frequency receiver with integrated communications
Trimble BD930-UHF
The Trimble BD930-UHF supports both triple frequency from the GPS and GLONASS
constellations plus dual frequency from BeiDou and Galileo. This compact board integrates the
latest generation of UHF receiver modems allowing the system to instantly receive corrections
from a large installed base of GNSS reference stations.

|
Key Features:
- 220 Channels for multi-constellation GNSS support
- EMI shielded module
- Compact design for mobile applications
- Integrated 403-473 MHz UHF receiver
- Flexible RS232, USB and Ethernet interfacing
- Centimeter level position accuracy

GNSS and communication tight integration
Taking advantage of Trimble’s expertize
in both GNSS and UHF communications
the Trimble® BD930-UHF module has
been designed for applications requiring
centimeter accuracy in a compact package.
By integrating wireless communications on
the same module the task of receiving RTK
corrections is greatly simplifi ed. A single
intuitive web interface allows a variety of use
cases to be supported.
Both GNSS and communication components
are fully shielded. This design ensures the
high quality signals are protected from the
sources of EMI on the host platform. It also
signifi cantly reduces radiated emissions
which speeds compliance certifi cation and
time to market.

Multi constellation GNSS
The Trimble BD930-UHF supports both
triple frequency from the GPS and GLONASS
constellations plus dual frequency from
BeiDou and Galileo. As the number of
satellites in the constellations grows the
BD930 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 BD930 contains an advanced kalman
fi lter PVT engine that delivers high
accuracy GNSS, DGNSS positions in the
most challenging environments such as
urban canyons. Diff erent confi gurations
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.

High performance integrated UHF receiver
Industry professionals trust Trimble
embedded positioning technologies as
the core of their precision applications.
With the latest Trimble-precise Maxwell™ 6
technology, the BD930 provides assurance
of long-term future-proofi ng and trouble-free
operation. Moving the industry forward, the
Trimble BD930 redefi nes high-performance
positioning:
- 70 MHz Bandwidth (403-473 MHz)
- High Over-the-Air Link Rates
- Industry standard link protocols
|
Flexible Interfacing
The Trimble BD930-UHF was designed for
easy integration and rugged dependability.
Customers benefi t from the Ethernet
connectivity available on the board, allowing
high speed data transfer and confi guration
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.
