        In general, measuring distance by dead reckoning from wheel or
track information may be useful, but trying to obtain heading from
relative track motion is too error-prone to use alone.  However,
if you combine a magnetic compass and relative wheel/track info,
you can get reasonably decent data.  The two must be combined in
the frequency domain, using suitable filters.  This is how the 
Etak system (inside the Blaupunkt Travel Pilot) does it.
