ComNav G2 and G2B GNSS Satellite Compass

ComNav G2 and G2B GNSS Satellite Compass

1 WEEK

Quick Overview

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.
