NMEA unveils standards updatePosted on
The National Marine Electronics Association released a significantly updated version of NMEA 0183, its well-known standard that enables the interfacing of marine electronics.
Version 4.10 will improve boating safety and navigation through updates and expansions of electronic communications data “sentences” pertaining to a number of navigation and communications devices, including Galileo satellite receivers and Automatic Identification Systems, according to the NMEA.
The NMEA standard consists of sentences, the first word of which, called a data type, defines the interpretation of the rest of the sentence, according to the NMEA website. Each data type would have its own unique interpretation and is defined in the NMEA standard.
NMEA 0183 defines electrical requirements, data transmission protocol and timing, and specific sentence formats for a 4800-baud serial data bus.
Version 4.10 impacts shipboard, non-shipboard and land-based equipment as well as networks for maritime and other industry use. The standard has been expanded to include the new Galileo Global Navigation Satellite System, or GNSS. Many of the existing GNSS sentences were extended to accommodate Galileo and future GNSS improvements.
