Since ancient times, human beings have looked to the heavens to find our way around on Earth. It was only a few hundred years ago that we developed systems to plot latitude and longitude fixes based on the positions of celestial bodies, and the common practice of celestial navigation by means of a sextant emerged. The basic premise of celestial navigation relies on calculating angles between the observer, the horizon, and a predictable celestial body such as the sun, moon, or visible planets and stars.
In the modern age, we’ve become dependent on highly precise and user-friendly navigation technology – but technology can fail – and then what? For safety and self-sufficiency, celestial navigation remains an essential skill for every ocean-going mariner.
With the ASA 107 course, you will learn to:
- apply celestial navigation theory and practices for safe navigation of a sailing vessel in offshore waters;
- use the sextant to determine your vessel position by the Local Apparent Noon method; and
- deduce your location with sun, moon, planet and star lines of position and fixes.
