One sight at local noon yields your latitude and longitude.

Poor Ole Thom who claims to have used a sextant seems to
not understand this simple fact.

1) the angle of the sun at local noon gives you your latitude.

2) the time differential of the sun's azimuth from Greenwich
mean time gives you the longitude. Expensive chronographs
are no longer necessary. GPS time is plenty accurate enough
as well as a good quartz watch set to radio signals from WWV.

I can take one noon sight anywhere in the world covered by the
tables I have on board, correct it for errors and come up with
my position within ten miles easily every time provided it is not
overcast, raining or some such.

Celestial navigation in its most basic form - the noon sight - is
no mystery. Why, I bet even otnmbrd and Shen44 are able to
do it which means any old moron can do it - even Bobsprit most
likely.

S.Simon - has taken more noon sights than cherries!
