How does GPS assist in navigation?

GPS, or Global Positioning System, is a satellite-based navigation system that provides precise positioning information by utilizing signals from a network of satellites in orbit around the Earth. This technology allows users to determine their exact location in terms of latitude and longitude, which is essential for navigation in various contexts, including maritime, aerial, and terrestrial travel.

The system works by receiving signals from multiple satellites, which are then used to compute the user's precise location through a process known as trilateration. This capability is particularly advantageous in navigation as it enables sailors, aviators, and drivers to accurately plot their course, monitor their movements in real time, and efficiently reach their destinations.

In contrast to the correct answer, the other options focus on unrelated aspects of navigation. Weather updates and maritime warnings are essential for safe navigation but do not constitute the location-determining features of GPS. Details about fishing regulations and zones are important for compliance and safety but are not directly linked to the geographical positioning aspect of navigation. Furthermore, calculating fuel consumption based on speed is a useful navigational consideration but relies on positional data already established by systems like GPS rather than being a function of GPS itself. Thus, the unique ability of GPS to provide exact positional information firmly establishes it as the critical
