ACCURACY OF MARINE NAVIGATION

Captain P. V. H. Weems

Peer Reviewed

Abstract:	Modern navigation might be dated from the invention of the marine sextant in 1734, followed by the invention of the marine chronometer in 1766. These developments made it possible to determine longitude as well as latitude at sea. The steady developments of nautical tables, almanacs, and the further refinements of sextants and timepieces gave an accuracy of position under good conditions at the turn of this century within two miles and this with a speed of solution based on four stars, of about half an hour.
