GPRMC & GPGGA decoder

This page lets you decode some of those weird strings your GPS outputs.

$GPRMC,001225,A,2832.1834,N,08101.0536,W,12,25,251211,1.2,E,A*03
If you have strings that look like the example above, you can try to decode them here.

You can decode NMEA strings starting with ××RMC or ××GGA. ”××” is the talker ID, some examples are in the table below. Only the orange ones work here.

××RMC Contains position, velocity, and time.
××GGA Gives time, position, altitude, and fix quality.

Enough talking – insert your NMEA sentence below and hit Decode!

Page not suited for small screens. It will just cause frustration to copy/paste long NMEA strings and scroll around maps and tables. Use proper equipment :)
