Celestial Navigation 360

Description

Celestial navigation exploits the principle that every measurement taken with a sextant (a 'sight') converts to a line of position on a chart, the intersections of two or more such lines providing a position fix.

Use this offline compatible app to plan/enter sights and inspect the resulting lines of position.
