Just downloaded sun surveyor lite (free), one of 22 apps -others up to $20,
etc. Shows position of sun based on PP (present position). Easy for it to
do inverse based on possible position - info since last fix (known
position).

Well, I MEANT "dead reckoning (DR)." It really comes from "deduction"
reckoning and should be "ded" reckoning, but "everybody" calls it "dead,"
and, of course, it nearly is with all of the equipment these days carrying
a "running" fix. ;<)

OK, I saw the key two words the second time I read it - "in part." Sun
can give you only ONE "line of positions" (LOP) - a huge circle on the
earth; ya gotta know about where ya are for this info to be any good, i.
e. - dead reckoning (RD), for example - projecting info from last known
position to reckon/guess present position. Using old info plus sun LOP,
you can reckon/guess a "most probable position" MPP - lot better than
nothing and is "neat," anyway - handheld astrotracker. Now, if it could
track stars --. ;<)

If it can't pick up a GPS signal, the all-new S-Class can
actually determine where it is based in part on the sun's
position in the sky. Now that's a bright idea.
