A sextant is a doubly reflecting navigation instrument that measures the angular distance between two visible objects most often to find a position between the sun and the horizon. Obtaining this angle is called "taking a sight" If the sun is directly overhead, the sextant measures the angle from the horizon up to the sun. In this case, the angle would be 90 degrees.

Every degree = 60 miles. If the sun were 1 degree away from directly overhead, the sextant would read 89 degrees. Then you would know that your position is somewhere within a 60 mile circle, because 1 degree = 60 miles. 

Also used of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.
