Abstract
A method for determining a compass heading in a manner that reduces the influence of magnetic noise. The methodology can evaluate changes between various parameters, such as a prior magnetic field parameter and a current magnetic field parameter and/or a prior compass heading parameter and a current compass heading to select an algorithm for use in calculating a new compass heading.
