1. Sextant
   Navigation instrument measuring solar and stellar heights. Used on land since 16th century – the naval version was developed in 1757 by Captain John Campbell. The name refers to a sixth of a circumference – 60°. Thus the sextant can measure angles to 120°. The octant operates in a similar way but measures smaller angles.
