Beskrivelse
Navigate like the explorers did — by the sun, moon, and stars.
Sextant is a complete celestial navigation toolkit that turns your iPhone into a learning instrument for one of humanity's oldest skills.
Whether you're a sailor who wants a backup to GPS, a student studying astronavigation, or simply curious about how people crossed oceans before satellites, Sextant gives you everything you need.
**Take sights with your camera**
Use your device's camera and motion sensors as a digital sextant. Calibrate the horizon, align a celestial body, and lock your reading — the app handles the math from there.
**Or enter readings from a real sextant**
Own a traditional sextant? Enter your altitude readings manually and let Sextant reduce the sight with full correction breakdowns: index error, dip, refraction, semi-diameter, and parallax — all computed from actual ephemeris data, not static tables.
**Full almanac built in**
Sun and Moon positions are computed from astronomical models (Meeus), not looked up from outdated tables. Twenty navigation stars — from Polaris to the Southern Cross — are included. No internet connection required.
**Plot your fix on a real map**
Every sight produces a line of position drawn on an interactive map. Take multiple sights, apply dead reckoning between them, and watch your running fix come together — just like it works on a paper chart.
**Learn the whole workflow**
A built-in guide walks you through every step: choosing a body, taking the sight, understanding corrections, and plotting the result. Reference tables for dip, refraction, and semi-diameter are always a tap away.
**Tools included**
- Starfinder: see which bodies are above the horizon right now
- Sight reduction calculator for manual what-if scenarios
- DMS/decimal angle converter
- Complete correction and reduction tables
No subscriptions. No ads. No internet required. One purchase, everything included.
