NMEA 0183 Interface Standard

The NMEA 0183 Interface Standard is used worldwide across many industry segments. The standard defines electrical signal requirements, data transmission protocol and time, and specific sentence formats for a 4800-baud serial data bus. Each bus may have only one talker but many listeners. This standard is intended to support one-way serial data transmission from a single talker to one or more listeners. This data is in printable ASCII form and may include information such as time, position, speed, water depth, etc.

Please note that certain websites offer explanations and examples of NMEA 0183 sentences. In most cases they are very old versions or incorrect interpretations and should not be depended upon for accuracy.
 The NMEA 0183 Interface Standard is a COPYRIGHTED document and available only from NMEA. Other Internet offerings are not authorized and may constitute a copyright infringement.

Latest Version of NMEA 0183 (Version 4.11)
As of November 2018, NMEA has published a new version of NMEA 0183—Version 4.11, which replaces Version 4.10 and includes updates to the entire suite of GNSS (Global Navigation Satellite System) sentences. This includes interface clarification for the use of GPS (US), GLONASS (Russia), GALILEO (Europe), BDS (China), QZSS (Japan), and NavIC ((IRNSS) (India)). Deployment of these new systems ramped up the need for sentence updates. Also included are new Navigation Satellite System Receiver Talker Identifiers and Sentence Formatters, an expanded GNSS Identification Table and examples of the use of the satellite systems.
