Which X2-Configured Airmar Parameters Require a Satellite Connection?
The following Airmar WX-Series parameters, that are compatible with an X2 data logger, require a satellite connection to record measurements.
(Read the Airmar X2 Integration Guide article to learn about the Airmar WX-Series parameters available for the X2.)

| $GPGGA | NMEA 0183 standard GPS Fix Data | UTC Time (hhmmss) Latitude (Degree) Longitude (Degree) Altitude (m) |
| $GPVTG | NMEA 0183 standard Course Over Ground and Ground Speed | Course Over Ground- COG (True Degree) Speed Over Ground- SOG (Magnetic Degree) |
| $WIMDA | NMEA 0183 Standard Meteorological Composite (Wind parameters with respect to north) | Wind Direction (Degree) Magnetic Wind Direction (Degree) Wind Speed (m/s) |
| $HCHDT | NMEA 0183 standard Heading relative to True North | Heading (True Degree) |
| $HCHDG | NMEA 0183 standard Heading, Deviation and Variation | Heading (Magnetic Degree) |
