Overview

The HPT435BT 35W UHF radio transceiver from JAVAD GNSS provides a high-speed point-to-point and point-to-multipoint wireless data transfer at up to 38.4 kbps, and offers USB/Bluetooth® capabilities with built-in wireless link monitoring.

The HPT435BT is programmable in frequency ranges from 406 to 470 MHz with channel spacing of 25 kHz, 20 kHz 12.5 kHz, 6.25 kHz. It is compatible with Pacific Crest, Satel, and Trimble protocols and can be used in the existing networks. The output power is programmable from 0.32 Watt to 35 Watts. This transceiver has DBPSK, DQPSK, D8PSK, D16QAM, GMSK, and 4FSK modulations with advanced forward error correction and data scrambling.

The HPT435BT supports user-selectable modulation techniques (GMSK, 4FSK, DBPSK, DQPSK, D8PSK, or D16QAM), which allows the user to achieve the highest data speed for a given range (up to 48 miles/77 km). It also includes a selectable error correction, which improves the functioning of the radio modem under interference.

The sophisticated features of the HPT435BT include data scrambling, frequency hopping, user-selectable transmit output power level, low power consumption sleep modes, autoscanning for the base, and plugand-play installation for remote terminals.

The built-in software tools provide the wireless link testing, status, error statistics monitoring, and the unit’s settings change over the air. The firmware of the HPT435BT radio transceiver resides in flash memory. The updating of the radio modem programs is entirely software-based. The flash memory is re-programmable through an RS232 interface, USB, Bluetooth, or over the air.
