What is NMEA Data?

    NMEA (National Marine Electronics Association) data is a standard language most GPS receivers communicate with.
It is an ASCII data representation of position, satellite data and other data associated with the GPS receiver.
Below is an example of a NMEA sentence:

        $GPGGA,060003,3348.784,N,11754.064,W,1,07,1.0,66.2,M,-31.9,M,,*45

    This sentence contains the position of N 33' 48.784" latitude, W 117' 54.064" longitude and an altitude of 66.2 meters. The time is showing 06:00:03 UTC.

    See Also: I see data from my GPS, but none of the controls are working



    Most GPS receivers output a standard protocol defined by NMEA (www.nmea.org).
This protocol holds information about the position, satellite status and other navigation status.
Some GPS receivers send a select few commands while others have the ability to enable or disable specific NMEA sentences.

Supported NMEA Sentences

    Our products support a specific set of NMEA sentences from the GPS receiver. They are:
    NMEA ID     Description
    GGA     Global Positioning System Fix Data - reports time, position and fix related data
    GSA     GNSS DOP and Active Satellites - reports which satellites are being used for navigation and DOP (dilution of precision) values
    GSV     GNSS Satellites in View - reports the signal to noise ratios for each satellite tracked as well as the azimuth and elevation of each satellite
    RMB     Recommended Minimum Navigation Information - Reports cross track error, destination waypoints, range to destination, bearing, etc.
    RMC     Recommended Minimum Specific GNSS Data - Reports position, speed, course over ground and date
    ZDA     Time and Data - reports time and date

Some GPS manufacturers have the ability to disable NMEA output as well as enable or disable individual NMEA sentences.
Consult your GPS manual for more information.
