Which feature of ECDIS provides real-time position updates?

• A. AIS
• B. Radar overlay
• C. GPS integration
• D. Chart auto-update

Answer: (C)

The feature of ECDIS that provides real-time position updates is GPS integration. This is because GPS (Global Positioning System) is a satellite-based navigation system that allows for the accurate determination of a vessel's position in real-time. When integrated into an ECDIS, GPS continuously supplies the system with the ship's current coordinates, which are crucial for navigation and ensuring safety at sea. The seamless integration of GPS data into ECDIS enhances situational awareness, as mariners can see their exact location on electronic charts while en route, effectively supporting decision-making in navigation. This real-time positioning capability is critical for avoiding hazards, ensuring adherence to planned routes, and complying with maritime regulations. While other features like AIS (Automatic Identification System) and radar overlays enhance situational awareness and safety by providing supplemental information about other vessels and environmental conditions, they do not directly provide real-time positioning of the vessel itself. Similarly, chart auto-update features ensure that the navigational data is current and updated but do not influence the real-time positioning of the ship. Thus, GPS integration is essential for monitoring and displaying the vessel’s position accurately during navigation.
