What three inventions led to the age of discovery?

The Age of Discovery was significantly influenced by three key inventions: the compass, which allowed for better navigation and orientation at sea; the astrolabe, which enabled sailors to determine their latitude by measuring the position of celestial bodies; and advanced ship designs, such as the caravel, which featured improved sails and hulls for greater speed and maneuverability. Together, these innovations facilitated longer ocean voyages, enabling explorers to chart new territories and expand global trade routes.
