What is the purpose of the Global Positioning System (GPS) in maritime navigation?

The Global Positioning System (GPS) plays a crucial role in maritime navigation by providing accurate positioning and navigation information. This system utilizes a network of satellites that transmit signals to GPS receivers on vessels. By calculating the time it takes for signals to travel from multiple satellites, the GPS can determine the vessel's precise location in terms of latitude, longitude, and altitude.

Knowing an accurate position is essential for safe navigation, helping mariners to avoid hazards, maintain course, and ensure efficient routing. GPS allows for the real-time tracking of positions, making it vastly superior to traditional navigation methods, which might rely on celestial navigation or terrestrial landmarks. As a result, GPS has become a fundamental tool in modern maritime practices, enhancing safety and operational efficiency on the water.

While some other options mention important functions related to maritime operations, they do not focus on the core capability of GPS, which is reliable positioning and navigation.
