Navigation: Navigation refers to the process of determining one's position and planning routes while traveling on water. It involves using various tools and techniques to guide ships safely through unfamiliar waters.
Compass: A compass is a navigational tool that uses Earth's magnetic field to determine direction. It consists of a magnetized needle that aligns with the Earth's magnetic north pole, helping sailors maintain their heading even when visibility is limited.
Astrolabe: An astrolabe is an ancient astronomical instrument used for celestial navigation. Sailors would use it to measure the angle between celestial objects (such as stars) and the horizon, enabling them to calculate latitude while at sea.
