GPS Compass Units & Floating Core Magnetometers

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.

The ComNav G2 and G2B GNSS Satellite Compass provides true heading measurement with an accuracy of 0.25° 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. The system is IMO compliant and Wheelmark and USCG approved, and may be used as a primary heading source.

The ComNav G2 GNSS Satellite Compass with Navigator G2 Display provides true heading, GPS position data, gyro data and speed log in a single display. The system uses differential GPS to measure heading and therefore is not subject to magnetic variation or deviation. Heading data is transmitted to an autopilot via a standard NMEA0183 data output.
