Over thousands of years humans have relied on their intuition as well as heavenly bodies and features in their local environment to find their way across our planet. Today we have abandoned most of these techniques as we increasingly rely on satellite navigation. By learning some of the methods of navigation used by ancient mariners and the use of early instruments such as the sextant we can better appreciate our heritage and pass on some of these techniques to future generations.
