B20-Beacon GPS Receiver
Beacon GPS Receiver B20 is beacon channel GPS receiver, automatically selecting the nearest beacon station signal.
It can realize the navigation and surveying function without any investment of base station, and also have the ability of
static surveying measurement.
Beacon GPS receiver B20 can be generally applied in the offshore survey, river water survey, geodetic survey, field
navigation, port construction, dredger construction, geodetic control measurement, ect.
l No regional limitation: having differential function with both satellite differential and beacon differential, additionally
being able to use self-built differential data source to provide high precision real time results without any regional limitation.
l Easy to configure: switching the differential data source at any time, and checking the satellite and differential data
status through the control panel.
l Strong compatibility: Easy to connect with many kinds of external equipments, such as Navigation Equipment,
Radar, Echo Sounder, ect.
l Standard data output format: NMEA 0183 data format, and also the CHC self-defined data format. WINDOWS platform: providing the configuration software based on WINDOWS
l High output frequency: Maximum output rate is 20Hz, modifiable according to the customer requirements.
l High precision: Being able to provide 1pps output rate.
Differential Position: Less than 0.75 meter horizontal RMS positioning accuracy (at least 5 satellites in view and
