Offline position fix via the sun, moon, stars and planets
Each measurement taken with a sextant (a 'sight') converts to a line of position (LoP) on a chart, the intersections of two or more such lines providing a position fix.
Use this app to plan/enter sights and graphically inspect the resulting LoPs
Features -
