Nmea 0183 Versions [better] -

1. Introduction NMEA 0183 is a voluntary communication standard developed by the National Marine Electronics Association (NMEA). It defines electrical and data protocol specifications for communication between marine electronic devices (e.g., GPS, echo sounders, autopilots, wind sensors). Unlike its successor NMEA 2000 (a CAN-based network), NMEA 0183 is a simple, asynchronous serial line protocol. This report traces its version history, highlighting key changes in baud rate, sentence structure, and data fields. 2. Version Overview NMEA 0183 has undergone several major revisions. The most widely implemented versions are 2.0, 2.1, 2.3, 3.0, and 4.0 (with 4.10 and 4.11 as minor updates).
