Nowadays, it's all GPS. ------------------- The "sextant", from the latin word for "six", is one-sixth of a circle, and is the primary tool used in celestial navigation. However, before the sextant came into widespread use, the "quadrant" of a quarter-circle and the later "octant", an eighth of a circle, were used.
