omar28744 0:cf5854b3296f 2 TinyGPS++ - a small GPS library for Arduino providing universal NMEA parsing
omar28744 0:cf5854b3296f 3 Based on work by and "distanceBetween" and "courseTo" courtesy of Maarten Lamers.
omar28744 0:cf5854b3296f 4 Suggestion to add satellites, courseTo(), and cardinal() by Matt Monson.
omar28744 0:cf5854b3296f 5 Location precision improvements suggested by Wayne Holder.
