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 -
* The 58 navigational stars of the Nautical Almanac.
* Realtime computed horizon in panoramic projection. Use for star/planet identification, sight preparation, true bearings etc.
* Sight reduction, ephemerides calculated internally
* Lines of position plotted on a pan/zoom grid centered on Assumed Position (intercept method)
* Import sights from companion app Angular Distance (uses camera as sextant)
* Rising/setting almanac
* Lunar distances conversion to Universal Time
Premium Subscription -
All features extended to the sun, moon and planets
