NMEA GGA Message

The GGA Format provides essential fix data which includes 3D location and accuracy data.

Example message:

$GPGGA,123519.00,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47

NOTE: The GGA format does not support precision timing and 1PPS functionality; the Web UI may permit the selection of Message or PPS Pin as PPS Source, but the NMEA GGA Message will not use either. If this data is required for your application, use the ZDA Message format instead (see NMEA ZDA Message).

Where:

GGA Global Positioning System Fix Data
