Anymore, it's a GPS (global positioning system). It used to be a sextant. The sextant could, using multiple sightings, give a sailor a "fix" or location. Other methods include loran, which is a set of transmitters that send out signals at precise times. The difference in the times at which the signals of two transmitters (positioned "usably") arrived applied to a map would get a "curve" along which the ship is located. Another set of readings would get another "curve" and the point at which the two crossed gave a fix. My, how times have changed. See the links below for more information.

Things nautical. The sea and ships.
The science of navigating ships from one location to another is known as navigation. It involves determining a vessel's position using various techniques such as celestial navigation, satellite-based GPS, and dead reckoning. Navigators calculate the course and distance to be traveled by considering factors like wind, currents, and weather conditions, ensuring safe and efficient passage. This discipline combines elements of geometry, physics, and geography to guide vessels accurately across water.
it is ETHNOLOGY....the study of chracteristics of different people and the relation ships among them...ans by dia baig from pakistan
These are many ways in which Greek science helps us today.science have many branches and Greek scientist helped in many branches,like : Astronomy,Architecture etc Archimedes told us the way how to check golds purity.Buoyancy principle helped us in building ships. Forensic science is also the gift of Greece.

Prince Henry used a scientific way of determining the ships sailing, direction, and the location.

Two ships sailing in the same direction can reduce the risk of collisions by maintaining a consistent course and speed. It also makes it easier for one ship to overtake another, minimizing potential hazards. Coordination in direction can help ships maintain a safe distance and facilitate communication between them.
Imaginary lines on the globe, such as the equator and meridians of longitude, help ships navigate by providing reference points for determining direction and location. These lines help sailors plot courses, calculate distances, and establish time zones, contributing to safe and efficient navigation at sea.
