Which function was enabled by the geared mechanism within medieval Islamic mechanical astrolabes?

💡 Explanation

When Islamic scholars integrated geared mechanisms into astrolabes, it enabled automated calculations of planetary orbits based on Ptolemaic models because the gears could simulate the epicycles and deferents. Therefore automated calculation resulted, rather than easier measurement, simplification of projections, or predictive phases that do not rely on complex gear systems.
