Trimble HPB450 450 - 470 MHz High Power Base

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
