Which issue influenced by astrolabe inaccuracy impacted ancient navigation?

💡 Explanation

Celestial navigation relied on accurate altitude measurements, but parallax error led to calculation errors, because the instrument axis wasn't perfectly aligned. Therefore altitude calculation drifts and is a bigger issue, rather than thermal expansion or mechanical limitations impacting worm gears.
