NMEA and Multiplexers
The NMEA standard, a communication standard defined by the NMEA organisation, defines a communication protocol called NMEA-0183, that enables navigation instruments to exchange data with eachother.
A compass can, for example, send a bearing to a radar to enable a north-up display. And a GPS can send cross-track information to an autopilot in order to steer a programmed course.
