Introducing Iridium GMDSS
Iridium GMDSS is a next-generation satellite safety communication solution designed for SOLAS vessels. It provides truly global coverage, including polar regions, ensuring vessels can send distress alerts and communicate with rescue coordination centers from anywhere at sea.
Unlike traditional regional systems, Iridium operates on a global low-earth orbit satellite network. This guarantees continuous availability, reliable voice communication, and automatic position reporting worldwide.
Integrated within Castor Marine’s hybrid connectivity approach, Iridium GMDSS forms the certified safety backbone of your vessel’s communication infrastructure.
