Hemisphere GNSS - SBX-4 DGPS Beacon OEM Board 1

SBX-4 DGPS Beacon OEM Board

DGPS Beacon Module


Provide a reliable source of differential corrections with the SBX-4 radiobeacon board that augments a separate GPS receiver with free accuracy-improving correction data from networks of beacon stations located throughout the world.


With dual-channel architecture to ensure the best station is always being decoded, the SBX-4 DGPS Beacon OEM Board delivers high performance reception and a wide range of functionality including the capability to be tuned to signal strength or station distance.


The SBX-4 outputs the industry standard RTCM SC-104 format accepted by differential-ready GPS receivers and can also be configured and monitored with NMEA 0183 protocol.
