GPS
GPS (Global Positioning System) is a satellite-based navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth. It is operated by the United States government and freely accessible to anyone with a GPS receiver. The system consists of a network of satellites in orbit, ground control stations, and GPS receivers. GPS is widely used in the maritime industry for navigation, vessel tracking, and search and rescue operations. It allows ships to determine their precise location, speed, and course, and to navigate safely through narrow channels and congested waters. GPS has revolutionized the way ships navigate and has greatly improved safety at sea.
