Refine celestial navigation by applying index error, height of eye (dip), and main corrections to sextant readings to determine geographic position, including longitude as the Greenwich angle per Nautical Almanac.
Learn to determine sea position with the sun line method by measuring the sun, using the nautical almanac, building a triangle with an assumed position, solving the spherical triangle, and plotting lines of position.
Explore advanced celestial navigation by mastering the sextant, Nautical Almanac, and accuracy corrections, then compare using reduction tables with direct height and azimuth calculations.
Learn to navigate by stars and planets, forming lines of position with star identification, nautical almanac charts, and planet readings; use Orion, Scorpius, and the Big Dipper for fixes.
In this course, you will learn about the basics of celestial navigation, including all about sextants and how to use them, as well as the navigational math required in celestial navigation. Eventually, we move onto pretty advanced topics such as sextant adjustment and using the Moon, Stars, and Planets.
This course is designed for recreational or professional sailors and power-boaters interested in marine navigation, sailing using primitive navigation techniques, and self-reliance!
