There's a new version of TinyGPS
, my NMEA (GPS) stream parser library, available. Version 12 provides some simplified new examples and several new features:
satellites() – Number of satellites counter from $GPRMC
hdop() – Horizontal Dilution of Precision from $GPRMC — the smaller this value is the more confidence you have in the accuracy of the location reading.
course_to() – another Maarten Lamers’ borrowing that complements his distance_to() function
cardinal() – a nice little static function by Matt Monson that converts a course to a compass direction like “SSE”.
