An absolute "must-have" for offshore navigators and a readily accessible self-teaching tool.
By A14OJS0VWMOSWO on 2007-11-03
Written by physicist, pilot, sailor, and fifty-year veteran of celestial navigation John Karl, Celestial Navigation in the GPS Age is a practical guide to the skill and science of celestial navigation for offshore navigators. Compact without being abridged, Celestial Navigation in the GPS Age is tailor-written for the modern era of computers, calculators, and online resources. Though the traditional methods of "working a sight" is covered, the meat of Celestial Navigation in the GPS Age carefully instructs the reader in the use of a simple and inexpensive scientific calculator. From the basics of coordinates, to sun sight reductions and lunar distance sights, to sextant adjustments and altitude corrections, and an exhaustive wealth of appendices, Celestial Navigation in the GPS Age is an absolute "must-have" for offshore navigators and a readily accessible self-teaching tool.
Celestial navigation in the gps age
By A1TF3BJYHRW6S9 on 2008-01-26
I've read through,looked at several books on celestial navigation, a subject that has captured my interest. Mr. Karl's book offers about the clearest explaination of "the navigational triangle" that I have come on. Historical comment on the sad fate of Capt. Sumner, of Sumner line navigation is also interesting. A small reproduction of the painting, Capt. Sumner Discovers the Celestial Line of Position catches the viewers eye too.
Most interesting and encourageing to me was the following. In the section on the navigational triangle, the author made a statement that seemed wrong. Curious about this, I e-mailed the author, c/o his publisher, Paradise Cay Publications of Arcata California and Celestaire of Wichita, Kansas jointly, the people at Paradise Cay sent my inquire on to Mr. Karl, who was kind enough to respond, in effect, turning on the light in a poorly lit room.
