About Celestial Navigation 360

Determine your geographical position from the sun, moon, stars and planets

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.

Features

* Realtime computed horizon in panoramic projection. Use for star/planet identification, sight preparation, true bearings etc.

* Sight reduction (ephemerides calculated internally) for the 58 almanac-listed navigational stars. Extendable to the sun, moon and planets as an upgrade

* Lines of position (intercept method) plotted on a pan/zoom grid centered on Assumed Position

* Rising/setting almanac
