(Denizcilik) SEKSTANT: Esas itibarıyla, seyir subayları (Dz.) ve seyrüseferciler (Hv.) tarafından; güneşin, ayın bir yıldızın veya ufuk yukarısındaki bir gezegenin irtifa ve açısal yüksekliğini ölçmekte kullanılan alet. Tabii ufuk veya tavsiye ruhlusu ufkundan, yardımcı nokta veya yardımcı istikamet hattı olarak faydalanılabilir

One sixth of a circle or disc; a sector with an angle of 60°
A navigational device for deriving angular distances between objects so as to determine latitude and longitude

For several days things went along in about the same course. I took our position every morning with my crude sextant; but the results were always most unsatisfactory. They always showed a considerable westing when I knew that we had been sailing due north. I blamed my crude instrument, and kept on.

A double-reflecting instrument for measuring angles, primarily altitudes of celestial bodies
a measuring instrument for measuring the angular distance between celestial objects; resembles an octant a unit of angular distance equal to 60 degrees
A navigational instrument used to determine the vertical position of an object such as the sun, moon or stars Used with celestial navigation
It is constructed on the same optical principle as Hadley's quadrant, but usually of metal, with a nicer graduation, telescopic sight, and its arc the sixth, and sometimes the third, part of a circle
An astronomical instrument for measuring angles, primarily altitudes of celestial bodies, to determine latitude
> The backstaff was an early navigational instrument used to gauge latitude at sea It was replaced by a more accurate device called the octant The octant was replaced by an even more accurate instrument, the sextant, which is still being used today Note: Latitude is the distance north or south of the equator, which is measured on a map or globe in degrees along a meridian

An instrument for measuring angular distances between objects, used esp
An instrument, combining telescope and graduated quadrant, used for measuring angular distances, esp the altitude of sun, moon and stars Used at sea to determine latitude and longitude

Navigational instrument, formed from one-sixth of a circle
optical instrument used for the measurement of angular distance between two objects
A sextant is an instrument used for measuring angles, for example between the sun and the horizon, so that the position of a ship or aeroplane can be calculated. a tool for measuring angles between stars in order to calculate the position of a ship or aircraft (sextans , from sextus ). Instrument for determining the angle between the horizon and a celestial body such as the Sun, the Moon, or a star used in celestial navigation to determine latitude and longitude. It consists of a metal arc, marked in degrees, and a movable radial arm pivoted at the centre of the arc's circle. A telescope, mounted rigidly to the framework, is lined up with the horizon. The radial arm, on which a mirror is mounted, is moved until the star is reflected into a half-silvered mirror in line with the telescope and appears, through the telescope, to coincide with the horizon. The angular distance of the star above the horizon is then read from the graduated arc of the sextant. From this angle, the latitude can be determined (within a few hundred metres) by means of published tables, and by consulting an accurate chronometer the longitude can be established. Invented in 1731, the sextant replaced the octant and became an essential tool of navigation
