LATITUDE & LONGITUDE FROM THE NOON SUN
by John Karl
At last, a celestial navigation book that
depends only on the concepts of latitude
and longitude, there’s no need for spherical
geometry, calculators, trigonometry
tables, or mysterious “assumed” positions
in this method of celestial navigation. In
just eleven short pages, you’ll be able to
find your latitude and longitude from the
noon sun with just this booklet, a sextant,
and a watch – and using only simple
arithmetic. With the addition of a Nautical
Almanac, you can extend the same method
to all the navigational celestial bodies.
Experienced celestial navigators will enjoy a simple alternative to
the intercept method – one that doesn’t depend on sight reduction
tables, and one that yields latitude and longitude directly without
plotting. They will also be thankful for a simple method that allows
them to find their position after not practicing CN for some time.
And everyone will appreciate the booklet fitting inside a sextant
case, making a complete navigator’s go-kit that is handy for leg-toleg
hopping, emergencies, and lifeboats. It contains a reproducible
worksheet and a 4-year sun almanac which is useable to the year
2050. SC, 2007, 24 pages.
