        GPS is not a perfect technology (what is?). When standing still the output
of the GPS actually drifts a little. Most GPS units erroneously show
changing headings due to this (how can they know you're not moving?). Some
GPSs will simply hold the last valid heading realizing that you are probably
stopped. Some will just show "invalid heading". In any case, if you're not
moving there are no "two points" to get a heading, therefore anything the
GPS outputs is suspect. TTYL
