The National Marine Electronics Association (NMEA) has released a significantly updated version of NMEA 0183, its well-known standard that enables the interfacing of marine electronics, reports the Martime Executive. Version 4.10 will improve boating safety and navigation through updates and expansions of various electronic communications “sentences” pertaining to a number of navigation and communications devices, including Galileo satellite receivers and Automatic Identification Systems (AIS). NMEA 0183 defines electrical requirements, data transmission protocol and timing, and specific sentence formats for a 4800-baud serial data bus. Version 4.10 affects shipboard, non-shipboard, and land-based equipment as well as networks for maritime and other industry use. The standard has been expanded to include Galileo. Many of the existing GNSS sentences have been extended to accommodate Galileo and future GNSS improvements. Version 4.10 replaces V 4.00, created in 2008. The new version is backward-compatible to V 2.00. Read more about the changes here.
