How Iridium GMDSS Works
Upon the press of a button, Iridium® GMDSS-equipped terminals send definitive location and identification information to a Rescue Coordination Centre (RCC). With built-in Safety Voice, crews can speak to an RCC operator within 30 seconds.
Meanwhile, Iridium SafetyCast® proactively delivers navigational and meteorological information, advising the crew of hazards and supporting safety measures.
Iridium GMDSS Services
All Iridium Connected® GMDSS terminals include functionality for all satellite GMDSS services.
Our GMDSS services are closely monitored and overseen by the International Mobile Satellite Organization (IMSO) to ensure that they comply with the requirements set by IMO. We also conduct regular exercises in collaboration with IMSO to vigorously test the reliability and effectiveness of our GMDSS system. This ensures that our services are robust and accessible to seafarers everywhere at all times.
