NMEA is the abbreviation of National Marine Electronics Association (National Maritime Electronics Association. The Association is a private institution dedicated to research on marine electronic devices and has developed NMEA standards for communication interfaces and protocols between GPS (GPS) electronic devices.

NMEA is a set of standard information that defines the output of the receiver. There are several different formats, each of which is an independent ASCII format that separates data streams. The data stream length ranges from 30 to characters, the output is usually selected at intervals per second. The most commonly used format is "GGA". It contains the positioning time, latitude, longitude, height, number of satellites used for positioning, and other
