astrolabe
{n} an armillary sphere
A navigational instrument used to measure the vertical angle between the horizon or the horizontal plane at the observer, and a celestial feature An astrolabe is used to determine the geographic coordinates of points on the Earth's surface
an instrument that allowed sailors to measure latitude
a navigation instrument used to find the altitude of the sun or the pole star, from which the ships latitude can be calculated
(From the Greek "astrer" [star] and "labin" [to take] ) An astronomical instrument used by ancient Greeks and others to measure the height above the horizon of celestial bodies The Seaman's astrolabe was a simple device used for measuring the altitude of the sun or a star for fixing one's approximate latitude It consists of a heavy brass ring fitted with an alidade or sighting rule pivoted at the center of the ring Suspended vertically from a shackle at the top of the ring, the alidade was positioned to sight the sun or star and the angle was read off on scale marks on the ring
An instrument for observing or showing the positions of the stars
Type of early scientific instrument used for reckoning time and for observational purposes. Astrolabes can be traced to the 6th century AD; they came into wide use in Europe and the Islamic world in the early Middle Ages and were adopted by mariners by the mid 15th century. One widely used variety, the planispheric astrolabe, can be regarded as a rudimentary analog computer. It enabled astronomers to calculate the positions of the Sun and prominent stars with respect to both the horizon and the meridian
instrument to measure the positions of stars and figure out latitude
An astronomical instrument that measures the height above the horizon of celestial bodies (in particular, the sun or a star) Especially at sea, this technique enables seamen to estimate their approximate latitude
An instrument dating back to ancient Greek, Persian and Arab times for ascertaining the positions of the heavenly bodies It was primitively a kind of sextant, made obsolete by the eventual introduction of the quadrant and sextant
an early form of sextant
A 'star-taking' instrument formerly (in times past) used to take altitudes, and to solve other problems of practical astronomy
Instrument which provided a flat representation of the skies, used to determine astronomical data (such as the altitude of the stars or the hour of day) and also used as a navigational aid In addition, it provided astrological information for the drawing up of horoscopes
A stereographic projection of the sphere on the plane of a great circle, as the equator, or a meridian; a planisphere
An astronomical and navigational instrument for gauging the altitude of the Sun and stars
{i} instrument used for measuring altitudes (Astronomy, Navigation)
An ancient instrument for observing the position of celestial bodies
An optical instrument for measuring altitudes of celestrial objects, and generally employing a pool of mercury or a pendulum to determine the direction of the plumb line
It is now disused
