I think that a GPS receive some information about cardinal point... So it will be more simple to read these information than calculate some difference... But, as I say, I'm not sure :(
Hi,
No, it doesn't...The way to calculate bearing is to derivate your position over time to get a speed vector (Vx, Vy). You can then calculate the angle that vector form with North (simple trigonometry) and calculate current bearing (in degrees) or show a compass (same thing in a different referential).
The thing is, it works only if you're moving. -- Phyce _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
