Think NMEA 0183 is "old school"? Think again. Even with the rise of NMEA 2000 and OneNet, the 0183 standard is still the "ASCII of the sea"—the universal language that lets your GPS talk to your sonar, regardless of the brand.
Specifically limits the data to the Russian GLONASS constellation.
NMEA 0183 is an electrical and data standard for communicating between marine instruments such as GPS, echo sounders, anemometers, autopilots, and chart plotters.

As then-Director of NMEA Standards Steve Spitzer wrote in the September/October 2018 issue of ME Marine Electronics : “With deployment of new satellite systems BeiDou (China), QZSS (Japan), and NavIC (IRNSS), the push for updating the NMEA 0183 GNSS suite of sentences was in high demand. Therefore, NMEA has updated all of them in the new NMEA 0183 Version 4.11”.
Every standard proprietary or approved sentence follows a strict structural syntax:
Provides detailed information about visible satellites (elevation, azimuth, and signal-to-noise ratio). These remain segregated by Talker ID to accurately map specific constellation performance. NMEA 0183 v4.11 vs. NMEA 2000 Think NMEA 0183 is "old school"
Version 4.11 provided complete, structured updates to the entire GNSS sentence suite, including:
The definitive, authorized version of the NMEA 0183 standard is only available directly through the NMEA Store . Buying the official PDF ensures it includes all corrections and the most recent updates to the 4.11 standard.
In this post, we’ll dive into , exploring its features, why it matters, and where you can find official documentation. What is NMEA 0183? Specifically limits the data to the Russian GLONASS
While NMEA 0183 v4.11 is incredibly reliable, it is structurally different from its successor, NMEA 2000 (N2K).
