B1: NMEA Messages - Overview

Background information
National Marine Electronics Association is a standard for interfacing marine electronic devices. This chapter describes all
NMEA-0183 messages which can be output by the receiver.
A Talker ID appears at the beginning of the header of each NMEA message. The Talker ID can be user defined or standard
(based on the NMEA 4.0). This is usually GP for GPS, GL for GLONASS, GA for Galileo, BD for BeiDou or GN for
GPS/GLONASS/Galileo/BeiDou in any combination.
