NavList:

The April issue of the Cambridge’s “THE JOURNAL OF NAVIGATION” is now available online.

Two interesting papers, one by our NavList member George Huxtable.

Sadly, they are not available for free…

Journey to Work: James Cook's Transatlantic Voyages in the Grenville 1764–1767

George Huxtable, Ian Jackson

James Cook's expeditious crossings of the north Atlantic each year, 1764–7, are discussed, in the light of modern advice that direct westerly passages are impractical for a sailing vessel.

New Ideas for Celestial Navigation in the Third Millennium

This paper reports on innovative mathematical and analytical approaches to celestial navigation. Beyond the common-sense recommendation for automation of the calculations, it is necessary to consider the specific algorithms used. The advantages of these new algorithms become evident when navigational practice is extended beyond the usual twilight round of sights or the noon Sun line. But exploiting the full advantages of the algorithms would probably require new software. This leads us to consider the prospects of applying new information technologies to the task of taking celestial observations.
