The application publishes gps location of the spark core device every 15 minutes. Notably, this update adds glonass support and exposes some interesting data when not tracking. Like its predecessor, tinygps, this library provides compact and easytouse methods for extracting position, date, time, altitude, speed, and course from consumer gps devices.
When gps is properly connected to a host controller like arduino, it sends a neverending stream of characters, grouped into humanreadable clumps called sentences.
