Abstract:This is a short summary of a paper which shows what a navigator can do to fix his position at sea using basic equipment (sextant, hand-held compass, almanac, four-figure mathematical tables) without the help of dead reckoning or the benefits of GMT.To proceed from an almost complete absence of spatial and temporal data the navigator has to observe the sextant altitudes The GMT having been found, the navigator can easily deduce his longitude. With care the results for both the latitude and longitude can be obta… Show more
