Celestial Navigation vs Celestial Navigation 360

This app does all the calculations to reduce a sextant reading to a line of position on the map. All intermediate numbers are shown to check your manual calculations. • Perpetual nautical almanac • Calculation of the line of position (azimuth and distance) • Draws the line of position on the map. • Star Finder: just point your device to the sky to identify the navigational stars. • Save your readings, choose what to show on the map. A sextant is required to make full use of this app.

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 inspect the resulting LoPs -- Features -- * Realtime or frozen computed horizon in panoramic projection.
