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

Many ships can move in any direction including backwards
Primarily, radar is used in all aspects as a ranging device. It is extremely accurate in determining distances in navigation systems, fire control systems and tracking devices used on aircraft, ships, and missles. The specific military uses are tracking ships and aircraft and fire control systems for missles, ships and aircraft. They even use systems for conter battery, literally tracking an artillery shell and determining the location of the firing weapon.

Navigational instruments aid in determining the speed, position and direction of a sea craft. Examples of these devices are chip logs, parallel rules, sounding lines, dividers and nautical almanacs.
