GPRMC & GPGGA decoder


This is the best GPRMC decoder online! Or at least it was when I wrote it – thirteen years ago..!

There are many pages detailing the structure and contents of the NMEA sentences, so I will not go into that here. Instead, this page helps you decode those funny looking text strings your GPS spits out, like this:

$GPRMC,001225,A,2832.1834,N,08101.0536,W,12,25,251211,1.2,E,A*03

The GPS manufacturers (Garmin, TomTom, Magellan etc) have their own ways of interpreting the NMEA standard. The standard clearly says the date should be encoded DMY, but at least one GPS brand uses YMD. Such rogue NMEA strings cannot be reliably decoded here.

If you need to decode some strings, verify you’re a human!

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

Happy coordinating !
