Astrolabes are ancient astronomical instruments used to measure the altitude of celestial bodies, helping to determine time and geographic location. They can also be used to solve problems related to spherical astronomy, such as calculating the positions of stars and planets. By aligning the astrolabe with the horizon and a celestial object, users could derive important navigational and timekeeping information.

Why did they stop using the astrolabe to find longitude?
Astrolabes can still be found in use today to measure the amount of day light remaining or for general navigation. The Astrolabes was replace by the easier to use Davis quadrant at the end of the 17th century.
What instrument were used to figure out position from the stars temple in mecca?
In ancient times, instruments like astrolabes and star charts were used to determine position using the stars in Mecca. Astrolabes measured the altitude of stars above the horizon, while star charts helped identify specific stars and their positions relative to Earth. These tools were essential for navigation and timekeeping.
What was used before a telescope?
Before the invention of the telescope, astronomers relied on the naked eye to observe celestial bodies. They used simple tools like astrolabes, quadrant, and armillary spheres to measure angles and track the positions of stars and planets. Observations were often made from high vantage points or through careful record-keeping of celestial events. These methods, while limited, laid the groundwork for later astronomical discoveries.
How astronomy is related to technology?
All of the observational tools needed by astronomers: astrolabes, quadrant, clocks, sextants, octant, spectrographs, polarimeters, telescopes, optical mount, radio telescopes, space telescopes, etc. are products of various technologies.
What was the medieval astrolabe?
The astrolabe is a very ancient astronomical computer for solving problems relating to time and the position of the Sun and stars in the sky. Several types of astrolabes have been made. By far the most popular type is the planispheric astrolabe, on which the celestial sphere is projected
