免費 · App 內購買
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.
-- Features --
* Realtime or frozen computed horizon in panoramic projection. Use for star/planet identification, sight preparation and entry, true bearings etc.
* Sight reduction (ephemerides calculated internally) for the 58 almanac-listed navigational stars. Extendable to the sun, moon and planets via subscription
* Almanac rising/setting/transits/twilights
* sextant-like functionality via the camera, suitable primarily for shooting the moon and the bright planets Jupiter and Venus.
