EDModern vessels rely on a sophisticated ecosystem of mechanical sensors and "airway" communication systems—specifically radio frequencies and satellite signals—to navigate safely and prevent collisions. At the heart of this protection is the Automatic Identification System (AIS), which utilizes VHF radio waves to broadcast a ship's position, speed, and heading to other nearby vessels and coastal authorities. Complementing this is the Marine Radar, which emits electromagnetic pulses to detect physical objects like other ships or landmasses, even in zero-visibility conditions like dense fog or heavy rain.
