Data Packets GPRMC


The GPRMC is a message of the NMEA standard. The NMEA standard uses a simple ASCII, serial communications protocol that defines how data are transmitted in a "sentence" from one "talker" to multiple "listeners" at a time.

The GPRMC log contains time, date, position, track made good and speed data provided by the GNSS navigation receiver. These messages will be output automatically after a valid almanac.

Example 1 (GNSS)

$GPRMC,144326.00,A,5107.0017737,N,11402.3291611,W,0.080,323.3,210307,0.0,E,A*20

Example 2 (Combined GPS and GLONASS)

$GNRMC,143909.00,A,5107.0020216,N,11402.3294835,W,0.036,348.3,210307,0.0,E,A*31
