A sextants a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.

Here's another documentary on navigation, (although the picture is not sharp) it's very informative. Duration: 52:22 minutes.

Footage: Euni Park
