The other reason your GPS says you are moving when you are not is so you can't "roll your own cruise missile"!

A military GPS won't do that.

Your smart phone gets better accuracy by using cell tower triangulation.
That falls down here 'coz I only get 1 cell tower.

If you want your trundle bot to move between waypoints you will have to live with a few metres of error.
The other thing I'm doing is using a digital compass, well 2 actually, one tilt compensated, one not.

The 2 digital compass' always agree on the heading, the GPS doesn't.
