What allowed for the age of exploration? (technologies)

Newly learned technologies like the building of caravels, usage of the astrolabe, new precision compasses and sextants, etc. allowed for the age of exploration.

Explanation:

The development of caravels by the Portuguese proved to be a boon for exploration. These new ships could sail windward that too at great speeds. The Europeans took from Muslim travelers the art of using the astrolabe which allowed them to determine their relative positions in the middle of the oceans. New magnetic compasses and advanced sextants offered greater precision and made exploration easier.
