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