An Electronic Chart Display (ECD) is a digital system used primarily in maritime navigation. It replaces traditional paper nautical charts with electronic versions that provide real-time information about a vessel's position, course, and surrounding environment. ECDs enhance safety and efficiency by integrating data from various sources, such as GPS and radar, allowing for better decision-making while at sea. These systems are often part of a broader suite of tools known as Integrated Bridge Systems (IBS), which streamline navigation and communication on ships. ECDs comply with international standards set by organizations like the International Maritime Organization (IMO), ensuring they meet safety and operational requirements for maritime activities.
