Celestial Navigation | Solar System
Learn how to use the observed positions of celestial bodies to determine your position at sea, and the calculations involved during navigation.
Celestial navigation requires an understanding of the solar system, its measurements and the calculations involved during the navigation of a shipping vessel. If you have an interest in celestial navigation, this free online course will help you learn about these procedures, as well as how to obtain the local hour angle and declination for the GMT.
