"Standards are the only thing keeping us alive right now," Elena shouted, stripping a wire with her teeth.
While NMEA 0183 remains widely used, particularly in legacy systems and certain market segments, the industry has evolved with newer standards. NMEA 2000 (introduced around 2001) replaced the simple serial bus with a robust CAN Bus network, which is multi-master (all devices can talk to each other), uses a binary data format, and operates at a much faster data rate of 250 kbps.
Even after purchasing the official Version 4.11 PDF, developers should be aware that NMEA published technical amendments to the standard. For example, Errata #0183 20190515 corrected the GNSS System Field in the GSV sentence to read “Signal ID” instead of “GNSS System”. An amendment for GDC (GNSS Differential Correction) sentences was also published in June 2019 and remains in force until incorporated into the next version. Nmea 0183 Version 4.11 Pdf-
