Measuring object and water, the angle between the antenna - celestial observation height and the horizontal angle between two objects and a single standard scale height of the vertical angle property.
Sextant is a precision angle measuring instrument, which consists of frame, optical systems and devices, angular reading of three major parts. Optical system including the telescope, moving mirrors, fixed mirrors and filters, etc.; angle reading device partakers degree arc, index rods, vernier drum wheel and so on. These components are installed in the aircraft body, and through the indicator lever? Angle optical system and reading devices connected into a whole. Sextant is based on geometric " triangle exterior angle is equal to the angles and the two are not adjacent, " " parallel lines alternate angles are equal " , " central angle of the arc it can be used to measure the distance " and other principles of measuring angles.PREFIX = O
