What is celestial navigation? 🌌
Celestial navigation is the practice of determining one’s geographic location on Earth by measuring the angles between celestial bodies like the stars, sun, or moon and the horizon. 🌞🌝✨
By combining these timed angle measurements with nautical almanacs, reduction tables, and some calculations, a sailor can accurately plot their position without the need for electronic instruments.
