LRIT is not part of the GMDSS communication requirements either but its equipment – particularly Inmarsat C and Mini C terminals – can also be used to support the system. Long Range Identification and Tracking (LRIT) of ships Dedicated SSAS models are also available from MES manufacturers.

Ship security alerts can be sent using Inmarsat C and Mini C, and relevant hardware and software can be added to the existing GMDSS terminals to support the service. Continue the ship security alert until deactivated and/or reset.Not send the ship security alert to any other ships.Be initiated by pressing a dedicated SSAS button and transmitting a ship-to-shore security alert to a competent authority designated by the administration, which may include the company, identifying the ship, its location and indicating that the security of the ships is under threat or has been compromised.IMO legislation states that the ship’s security alert system shall: The SSAS is used by ships to transmit a security alert to a competent authority when the security of the ship is under threat or has been compromised.

They advise on methods of using Inmarsat services and networks to comply with the following safety and security requirements for ships at sea. Inmarsat’s dedicated Maritime Safety Services team work closely with all organisations involved in the safety and security of ships and seafarers. Our SafetyNET, SafetyNET II and RescueNET services play a crucial role in enhancing the safety of life at sea by broadcasting Maritime Safety Information and Search & Rescue – related information messages to Inmarsat C, Mini C and Fleet Safety terminals. In May 2018, Fleet Safety, our next generation satellite safety service delivered over FleetBroadband and Fleet One , received formal GMDSS recognition by the IMO, marking the most significant advance in maritime safety for a generation. Our Inmarsat C service has been keeping seafarers safe at sea every day since the inception of GMDSS in 1999 through the receipt and transmission of vital ship-to-shore and shore-to-ship distress alerts. Inmarsat is the leading provider of GMDSS-approved satellite communication services.

Under the Safety of Life at Sea (SOLAS) convention, cargo ships of 300GRT and upwards and all passenger ships on international voyages must be equipped with satellite and radio equipment that conforms to international standards. The GMDSS is an international safety system, which uses satellite and terrestrial technology and ship-board radio systems to prevent accidents from happening and to automatically alert the rescue authorities and nearby vessels quickly in an emergency. Today, over our L-band network, we support both SOLAS and non-SOLAS vessels and some 1.6 million seafarers depend on us for a communications lifeline that is reliable and unaffected by bad weather. We’ve continued to ensure our safety services go above and beyond the IMO’s Safety of Life at Sea (SOLAS) and Global Maritime Distress and Safety System (GMDSS) requirements – by, for example, exceeding the demand for satellite and ground network availability of 99.9 per cent. When disaster strikes – a catastrophic storm, a collision, a medical emergency – seafarers know that they can rely on our safety services to get help fast. Safety is in our DNA – we were set up in 1979 by the International Maritime Organization (IMO) to provide reliable satellite safety communications.
