Innovations like the astrolabe, sextant, and magnetic compass were primarily used for navigation and maritime exploration.
1. **Astrolabe**: This ancient instrument was used to measure the altitude of celestial bodies, helping navigators determine their latitude while at sea. It could also be used for timekeeping and for various astronomical purposes.
2. **Sextant**: A more advanced navigational instrument, the sextant allowed sailors to measure the angle between a celestial object (like the sun or a star) and the horizon. This measurement enabled them to calculate their latitude and longitude, greatly improving the accuracy of navigation.
3. **Magnetic Compass**: The magnetic compass was crucial for navigation as it provided a reliable means of determining direction. It allowed sailors to orient themselves relative to the Earth’s magnetic field, which was especially valuable in conditions where celestial navigation was difficult due to bad weather or the absence of visible stars.
Together, these tools revolutionized exploration and trade by enabling more precise and reliable navigation, leading to the Age of Discovery and facilitating long-distance sea travel.
