Abstract
A method for removing noise from data in an electronic compass system which discounts noise values or outliers (extreme headings far from average) by displaying median headings in the absence of a clear trend in the direction of change of sampled headings. If a clear trend is detected, extreme headings are displayed. Compass jitter is reduced by requiring two consecutive differences be on the same side of the displayed heading before the displayed heading is changed.
