PGN 129029 (GNSS Position Data)
The NMEA 2000® GNSS Position Data PGN is translated to either the GGA NMEA 0183 sentence
entitled GPS Fix Data as shown in the previous section or it is translated to the GNS NMEA 0183
sentence entitled GNSS Fix Data depending on the state of field 7 of the PGN. If field 7 of the PGN
indicates “GPS”, then the GGA sentence is transmitted (see table under PGN 129026), if field 7
indicates “GLONASS”, then the GNS sentence is transmitted as shown in the following table.
