* Polynesians: Polynesian navigators used the stars, waves, and birds to travel vast distances across the Pacific Ocean.
Medieval Era:
* Arab astronomers: Arab scholars made significant contributions to astronomy and navigation, including the development of the astrolabe and the use of star charts.
Age of Exploration:
* Portuguese: During the Age of Exploration, Portuguese navigators heavily relied on celestial navigation to chart new routes and explore uncharted territories.
* Henry the Navigator: Though not a navigator himself, Henry the Navigator sponsored voyages and promoted the study of astronomy and celestial navigation in Portugal.
