A notable innovation during the Renaissance period that significantly impacted navigation was the development of the mariner's astrolabe. This tool allowed sailors to determine their latitude by measuring the angle of stars above the horizon, thereby improving the accuracy of sea voyages. The advancements in cartography and navigation techniques enabled explorers to venture further and with greater confidence. As a result, the Age of Exploration led to increased trade routes and cultural exchanges, fundamentally changing global trade dynamics and contributing to the rise of powerful maritime empires.
