A Full-featured GPS/NMEA Parser that has been tested with BufferedSerial

TinyGPS++ is a library for parsing NMEA data streams provided by GPS modules. Like its predecessor, TinyGPS, this library provides compact and easy-to-use methods for extracting position, date, time, altitude, speed, and course from consumer GPS devices. However, TinyGPS++’s programmer interface is considerably simpler to use than TinyGPS,

The library can extract arbitrary data from any of the myriad NMEA sentences out there, even proprietary ones
