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)


Example 2 (Combined GPS and GLONASS)
