Nmea 0183 Output

The technical anatomy of NMEA 0183 output is characterized by its simplicity and readability. The standard relies on a serial interface, typically transmitting data at 4,800 baud—a speed that seems archaic by modern internet standards but is perfectly adequate for the relatively small packets of navigational text involved. The output consists of "sentences" that begin with a dollar sign ( $ ) or an exclamation point ( ! ). Each sentence is an ASCII string of text, prefixed with a two-letter talker identifier (such as GP for a GPS unit or SD for a depth sounder) followed by a three-letter sentence formatter that describes the data content.
