Standard 4800 baud; High-speed (HS) variants up to 38,400 or 115,200 baud.
NMEA 0183 Version 4.11, released in November 2018, represents a critical pivot point in the evolution of maritime data standards. While newer networking protocols like NMEA 2000 have emerged, Version 4.11 solidified NMEA 0183's role in the multi-constellation era by expanding support for Global Navigation Satellite Systems (GNSS) beyond the traditional GPS The Shift to Multi-Constellation Support

Among its revisions, represents a refined iteration of the standard, specifically optimizing how modern satellite navigation data is structured and transmitted. What is NMEA 0183 Version 4.11?
NMEA 0183 Version 4.11 was a pivotal update, transitioning the standard from a primarily GPS-centric protocol to a truly global one, ready for the modern era of multi-constellation GNSS. Its formal support for systems like BeiDou, Galileo, QZSS, and NavIC ensured that NMEA 0183 could continue to serve as a reliable interface for a new generation of navigation devices. While it has since been succeeded by Version 4.30, the principles and structures defined in 4.11 remain highly influential, and its PDF documentation stands as a critical resource for developers, engineers, and technicians working with marine electronics, surveying equipment, and a host of IoT-enabled devices today.

A quick web search reveals many "summary" documents, blog posts, and third-party guides. While useful for an overview, these are for the official standard. Here is why obtaining the genuine NMEA 0183 Version 4.11 PDF is critical:
Once you obtain the authentic , here is how it is structured (chapter-by-chapter summary):
NMEA 0183 Version 4.11 is a electrical and data specification standard for interfacing marine electronic devices. It dictates both the physical signal characteristics (serial communications) and the specific sentence formats used to transmit data.
