30 Years of Inmarsat C

Monday 1, March 2021

30 years of the Global Maritime Distress and Safety System (GMDSS) service

Today, we mark 30 years of the Global Maritime Distress and Safety System (GMDSS) service, Inmarsat C.

Inmarsat C delivers 99.9% reliability to seafarers and Marlink is currently responsible for almost half of the global traffic on Inmarsat C, which forms the basis of vital maritime safety and vessel tracking and positioning systems.

In recent years, Marlink’s Inmarsat C traffic has shown continual growth, driven by our long-term knowledge, experience and solid partnerships, as well as the vital and continuous development of infrastructure to provide the highest Quality of Service (QoS), benefiting the safety of seafarers.

We manage the Inmarsat C traffic of the biggest service providers in the world, including Pole Star Global, CLS and SOREMAR, among others. As the preferred Land Earth Station Operator for 1/3 of all Inmarsat C users, we continue to create new Vessel Monitoring Service (VMS) business, in countries such as Tunisia, with services deployed on around 900 vessels.

The Marlink team has unrivalled knowledge and technical experience with Inmarsat C, resulting from the involvement of a dedicated group of technicians and engineers at both Aussaguel and Eik. This anniversary is a chance for us to thank the team for their hard work and achievements – our gratitude goes out to you all!
