ComNav G1 GNSS Satellite Compass

ComNav G1 GNSS Satellite Compass

Quick Overview

The ComNav G1 GNSS Satellite Compass provides true heading measurement with an accuracy of 0.5° RMS. The system uses differential GPS to measure heading and therefore is not subject to magnetic variation or deviation. Heading data is transmitted to an indicator or autopilot via a standard NMEA0183 or NMEA2000 data output.
