That's probably the inherent inaccuracy of a simple GPS receiver. Which is why, in http://www.basic4ppc.com/forum/open-...html#post36567 I included an averaging function.

Unfortunately I made the mistake of averaging the direction of travel too. When that alternates between 359 and 001 degrees the average comes out at 180, which is south rather than north! I haven't got a solution for that yet... (Klaus?)
