The new standard, NMEAaccommodates several gpvga at a higher baud rate, without using a central hub, or round-robin forkat buffering.

NMEA continued to be maintained separately: The checksum at the end of each sentence is the XOR of all of the bytes in the sentence, excluding the initial dollar sign.

At the application layer, the standard also defines the contents of each sentence message type, so that all listeners can parse messages accurately.

Through the use of intermediate expanders, a talker can have a unidirectional conversation with gpggaa nearly unlimited number of listeners, and using multiplexersmultiple sensors can talk to a single computer port. In the example, a sentence from the sample file is used.

This is in general use by AIS devices.

NMEA – Wikipedia

NMEA is a combined electrical and data specification for communication between marine electronics such as echo soundersonarsanemometergyrocompassautopilotGPS receivers and many other types of instruments. Although the standard calls for isolated inputs and outputs, there are various series of hardware that do not adhere to this requirement. The NMEA standard uses a simple ASCIIserial communications protocol that defines how data are transmitted in a “sentence” from one “talker” to multiple “listeners” at a time.
