National Marine Electronics Association (NMEA)

The National Marine Electronics Association, founded as an association earlier in 1957, was later incorporated in 1969.

To cite its current mission statement:

(NMEA) is the unifying force behind the entire marine electronics industry, bringing together all aspects of the industry for the betterment of all in our business.

It sets out combined electrical and data specification for communication between various marine electronic devices.

  • NMEA 0183 is the widespread standard superseding the earlier NMEA 0180 and NMEA 0182 standards.
  • NMEA 2000 is the latest standard.

The NMEA is a proprietary standard.
