How did new technology benefit Portuguese exploration exploration?

New technology significantly advanced Portuguese exploration in the 15th century, primarily through innovations like the caravel, a nimble sailing ship that could navigate both open seas and shallow waters. The development of the magnetic compass and astrolabe improved navigational accuracy, allowing sailors to venture further from the coast with greater confidence. Additionally, advancements in mapmaking provided more precise charts, facilitating longer voyages and the discovery of new trade routes. These technological improvements enabled Portugal to establish a dominant presence in maritime exploration and trade.
