← HistoryWhen Medieval navigators relied primarily only on astrolabes, which effect increased position error during ocean voyages?
A)Cumulative instrument and setup inaccuracy✓
B)Unpredictable stellar aberration deviation
C)Increased atmospheric refraction inconsistency
D)Variable gravitational tidal acceleration
💡 Explanation
Positional error increased because instruments accumulate small errors due to the imperfect construction combined with each measurement using angular values; therefore setup inaccuracy accumulates, rather than being corrected without cross-referenced measures.
