PGN 127250 (Vessel Heading)
The NMEA 2000
®
Vessel Heading PGN is translated to either the HDG NMEA 0183 sentence entitled
Heading, Deviation & Variation or it is translated to the HDT NMEA 0183 sentence entitled Heading,
True depending on the state of field 5 of the PGN. If field 5 of the PGN indicates “Magnetic”, then the
HDG sentence is transmitted; conversely, if field 5 of the PGN indicates “True”, then the HDT sentence
is transmitted as shown in the following tables.
