Celestial navigation, also known as astronavigation, is the practice of position fixing using stars and other celestial bodies that enables a navigator to accurately determine their actual current physical position in space or on the surface of the Earth without relying solely on estimated positional calculations, commonly known as dead reckoning.
Celestial Navigation: How Did Aviators “Shoot” the Sun and Stars? Open and Exposed On most early bombers and flying boats, such as this 1920s U.S. Navy Douglas PD-1, the navigator made sightings from the nose, where his view would not be obstructed by the biplane’s wings and struts.

Aug 25, 2020 · A hypothetical day at sea for the enthusiastic celestial navigator: sun LOPs, sun running fixes and a noon latitude all bookended with pinwheels of star, planet and moon sights at morning and evening twilight.
Celestial navigation is a scientific art form that uses the sun, moon, stars and planets for navigating across the surface of the earth. It may seem like a daunting prospect to master, but it is actually easier than you realise. Rather than learning everything at once, you can break it down into six main techniques.
