The invention of the astrolabe significantly aided sailors in the 1400s, allowing them to navigate more accurately by measuring the angle of celestial bodies above the horizon. This tool helped determine latitude, enabling explorers to venture farther from home with greater confidence in their ability to find their way back. Additionally, advancements in ship design, such as the caravel, improved maneuverability and speed, further facilitating long-distance sea travel.

The invention that helped sailors steer without seeing the sun or stars is the compass. Compasses use the Earth's magnetic field to show sailors which direction they are heading, helping them navigate even when visibility is poor.

An astrolabe helped sailors because it could determine any direction based on the position of the stars. This is why the astrolabe helped sailors.

Sailors used constellations as a navigational aid to determine their position at sea. By observing the position of specific constellations relative to the horizon, they could establish their direction and make adjustments to stay on course. This practice, known as celestial navigation, helped sailors navigate the open oceans before the invention of modern navigational tools.
The invention of the compass has helped people by providing a reliable method for navigation, allowing them to accurately determine direction. This has been particularly useful for sailors, travelers, and explorers in finding their way over long distances on land or at sea.
