TinyGPS++: A New View of Global Positioning

September 7, 2013

70

Announcing TinyGPS++ Today we’re happy to announce TinyGPS++, a completely new rethinking of TinyGPS, our popular Arduino NMEA (GPS) parsing library. NMEA defines how most GPS receivers talk. When GPS is properly connected to a host controller like Arduino, it sends a never-ending stream of characters, grouped into human-readable clumps called “sentences”: $GPRMC,045103.000,A,3014.1984,N,09749.2872,W,0.67,161.46,030913,,,A*7C $GPGGA,045104.000,3014.1985,N,09749.2873,W,1,09,1.2,211.6,M,-22.5,M,,0000*62 Obviously, [...]

Greater Accuracy with TinyGPS 13

TinyGPS 13 has been released. This latest revision improves the algorithm used to transform the raw NMEA latitude and longitude values into floating-point numbers representing decimal degrees. You may not have noticed any problem, but prior versions of TinyGPS generated values that were accurate to only about 5 decimal digits, or about 1 meter. Version [...]
