Iridium GMDSS Academy

Dedicated to preparing a new generation to traverse the high seas, the Iridium® GMDSS Academy provides an overview of Iridium Connected™ maritime safety services.

About The Academy

Mariners know how unpredictable the seas can be—and why reliable emergency communications make a lifesaving difference.

Recognized by the United Nations International Maritime Organization (IMO), the Iridium Global Maritime Distress & Safety System (GMDSS) connects vessels and their crews even in even the world’s most remote waterways.

About The Curriculum

This free curriculum delivers an overview of the Iridium Global Maritime Distress & Safety System (GMDSS) and Iridium Certus® services. As adoption of Iridium GMDSS continues aboard Safety Of Life At Sea (SOLAS) class vessels around the world, instructors are encouraged to integrate this content into their course material—thereby helping to prepare the next generation of seafarers in its operation, should the need arise.
