■FEATURES
Internal Differential Beacon Receiver
The DGPS 212 includes a Beacon Receiver and a GPS Receiver.
By using DGPS you can achieve true DGPS accuracy.
12-Channel Parallel for Receiving 12 Satellites
Simultaneously
The DGPS 212 is designed to simultaneously receive signals from
12 orbiting satellites, ensuring the most accurate positioning.
Quick Position Fixing
Typically 45 seconds for first position fixing without GPS almanac
data.
Conversion to NMEA0183 Output
Since the NMEA0183 output data is changeable between version
1.5 and version 2.1, you can connect the DGPS 212 to various
Marine Electronics Equipment such as Marine Radars,Fishfinders,
Plotters, or others.
PPS Signal Output
The DGPS 212 outputs a pulse per second which coincides with
UTC second precisely. It can be used as a precise clock.
