This course is a free introduction to the key concepts of celestial navigation for mariners. It is divided into three courses, Getting Started in Celestial Navigation, Going Further in Celestial Navigation and Advanced Concepts in Celestial Navigation. It is highly recommended to take these courses in this order.
After completion of this course, you'll learn how to use the sextant, how to bring the sun down to the horizon, how to calculate the latitude at noon, and other fundamentals. If you go no further than that, you're going to have a pretty solid foundation in basic celestial navigation.
