Which mechanism limited the accuracy of planetary positions projected by pre-17th-century astrolabes?

💡 Explanation

Astrolabe accuracy depended significantly on the precision of star catalogs; Ephemeris error occurred because planetary models and star positions in available hand-copied tables were often imprecise. Therefore the calculated planet's position suffered, rather than mechanical issues or environmental effects.
