AIS is totally dependent on which system for proper operation?

• A. Radar systems
• B. GPS
• C. Depth sensors
• D. Wind sensors

Answer: (B)

The correct answer is GPS, as the Automatic Identification System (AIS) relies heavily on precise positioning information to function correctly. AIS is designed to enhance maritime safety by allowing vessels to exchange information such as position, speed, and course. This information must be accurate and timely, which is where GPS plays a crucial role. The GPS system provides the exact geographical location, which is essential for AIS to determine and broadcast a vessel's position. Without GPS, AIS would be unable to provide the required data, leading to a severe reduction in situational awareness for both the vessel using the system and those that receive AIS transmissions. Other systems like radar, depth sensors, and wind sensors do not provide the foundational positioning data that AIS needs to operate effectively. Although these systems can complement navigational safety and situational awareness, they are not prerequisites for AIS functionality. Thus, GPS is the fundamental system upon which AIS is entirely dependent.
