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

💡 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.
