Trimble HPB450 Specs
The Trimble® HPB450 radio modem is
a powerful and rugged 450 MHz radio
specifically designed for GPS surveying
systems.
EXTREMELY long range and high power
The HPB450 offers high or low power
broadcast of GPS correction data. With its
high power output of 35 W, the HPB450 is
the most powerful radio of its type available,
maximizing the achievable range. With a fast
over-the-air data rate, the HPB450 also offers
reduced latency for improved GPS positioning
information.
Intelligent protocols and Autobase
technology
Unique AutoBase™ technology in the HPB450
radio offers the convenience of automatic
channel scanning; the radio scans through all
available channels and then returns to the
best one for transmission
Broadcast range and noise immunity are also
significantly enhanced via the HPB450 radio’s
forward error correction (FEC).
Seamless integration with Trimble
GPS systems
The HPB450 radio is designed to compliment
and fit seamlessly into new and existing
Trimble GPS surveying systems. As such, it is
built to the same standards of ruggedness,
reliability, and suitability for the field as
other Trimble products. It is lightweight and
consumes minimal power for longer field
operation, and you can rely on the radio to
perform in the field day after day, whatever
the conditions. With its built-in mounts the
radio can be mounted on any tripod.
The HPB450 is also easy to use, with a user
interface that includes a channel display, LEDs
to indicate system status, and on/off control.
Configuring the radio is also possible using
your Trimble field software or supplied PC
software.
Features:
- The surveying industry’s most powerful
radio for GPS base stations
- Rugged and reliable whatever the
conditions
- Intelligent and easy to use
- Compatible with any GPS surveying
system
