NMEA0183

  • The host control output NMEA0183 information from the serial port and analyzes NMEA 0183 sentence to output the information.
  • NMEA 0183 is a standard format developed by the National Marine Electronics Association for marine electronic equipment. It has now become a unified RTCM (Radio Technical Commission for Maritime Services) standard protocol for GPS navigation equipment.
  • NMEA 0183 includes 7 protocol frames including $GPZDA, $GPRMC, $GPVTG, $GPGNS, $GPGGA, $GPGSA, $GPGSV*3, $GPGLL, $GPGST, among which the first two characters followed by $ represent the country or region. For example, GPGGA stands for American GPS, BDGGA stands for China Beidou, GLGGA stands for Russia GLONASS, GAGGA stands for EU Galileo, and GNGGA stands for multi-satellite joint positioning.
  • Take $GPRMC as an example to briefly describe the information represented by each part of the protocol frame. Please refer to the File:NMEA0183.pdf for the other 6 protocol frames.
