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-capable app to plan/enter sights and inspect the resulting lines of position

A degree of sextant-like functionality is provided via the camera, suitable primarily for shooting the moon and the bright planets Jupiter and Venus
