The Global Maritime Distress and Safety System (GMDSS) is an international communication system designed to enhance maritime safety. It enables ships to send distress signals and receive assistance quickly in emergencies. GMDSS uses various technologies, including satellite communications, radio equipment, and digital selective calling, to ensure reliable communication between vessels and rescue authorities. Implemented by the International Maritime Organization (IMO), GMDSS aims to improve the safety of life at sea. It requires ships to carry specific equipment and follow established protocols for distress alerts, ensuring that help can be dispatched efficiently during maritime emergencies.
