Fellas,
The survivorlibrary also has a very good section on astronomy;
http://www.survivorlibrary.com/index.php...-astronomy
Most of the books in both sections (navigation and astronomy) are not too difficult to understand. It seems to me that present authors writing about similar subjects make them too complicated, full of slang and assumptions. A lot of these points apply to celestial navigation. It's probable that CN didn't pass away because of GPS but rather those interested in the theory and finer points of math took over the instruction and wrecked it rendering it incomprehensible. Lost is the method of "how" and present is the theory of "why".
As an example, think of the navigators onboard ships in the 1700's, 1800's and up to the mid 1960's who had no education or at best a high school education. They did CN and were successful in position finding.
