They developed knowledge of astronomy and constellations, linking celestial bodies with specific locations on Earth, which helped sailors navigate at sea. Greek astronomers and navigators used the 88 constellations and the positions of various celestial bodies for navigation, with the direction of the North Star being especially useful for determining a ship's course. The primary materials used include centrifuges and gold-plated vacuum tubes.
