The data is transmitted as "sentences" written in ASCII code. A single sequence of up to 82 characters. The start of the protocol is "$" followed by the comma and data fields separated by commas, and finally the & lt; CR & gt; & lt; LF & gt; (carriage return, line feed).

Sample NMEA sequence describing location in space and readability: $GPGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47
