What is Basics of Celestial Navigation about?

Celestial navigation utilizes 63 celestial bodies, including stars, planets, the moon, and sun, to determine position by taking lines of position (LOPs) from each visible body. During the day, only the sun and sometimes moon are visible, providing single or double LOPs. At night, many stars are visible along with planets, but the horizon is not, so observations must be taken at twilight when both are available. Celestial navigation assumes concentric celestial and terrestrial spheres to simplify calculation
