History

Which outcome occurred using historical astrolabes on ships that sailed near the poles?

A)Increased magnetic compass deviation error
B)Accurate declination value determination
C)Difficult altitude data measurement
D)Enhanced day length computation speed

💡 Explanation

Difficult altitude measurements occurred at high latitudes on ships using astrolabes because increased latitude causes lower altitude stars, weakening the instrument's Angle measurement accuracy due refraction, causing errors; therefore, data was less reliable, rather than more stable for navigation.
