The National Marine Electronics Association has published a new version of NMEA 0183-Version 4.11, which replaces Version 4.10. It includes updates to the entire suite of GNSS (Global Navigation Satellite System) sentences. The new version includes interface clarification for the use of GPS (US), GLONASS (Russia), GALILEO (Europe), BDS (China), QZSS (Japan), and NavIC ((IRNSS) (India)).
The association said in a statement that the deployment of these new systems ramped up the need for sentence updates. The version also includes new Navigation Satellite System Receiver Talker Identifiers and Sentence Formatters, an expanded GNSS Identification Table and examples of the use of the satellite systems.
"This comprehensive update has been examined, vetted and completed with a collaboration of a variety of organizations worldwide," said Steve Spitzer, NMEA director of standards, in the statement. "These include the NMEA 0183 Committee, USCG satellite experts, RTCM (Radio Technical Commission for Maritime Services) Special Committee 104, satellite system experts from BDS, QZSS and NavIC, IEC (International Electrotechnical Commission) Working Group 6, along with mobile device and chip manufacturers."
Spitzer said that NMEA 0183 continues to evolve outside of the marine recreational market. The terrestrial sector, including survey, mining, excavation and consumer goods, uses NMEA 0183 because of the growing integration of IoT (Internet of Things) and "Big Data" applications. SOLAS (Safety of Life at Sea) commercial vessels still rely heavily on NMEA 0183.
