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.
