The LT‑3100S Iridium GMDSS System is an advanced maritime satellite communication terminal providing 100 % global GMDSS coverage via the Iridium satellite network. Designed for professional vessels, it delivers critical safety services such as Distress Alert, Safety Voice, MSI (Maritime Safety Information) and supports voice, SMS, data and tracking functions. Compact and easy to install with a single cable solution, the LT‑3100S meets global maritime safety standards including IMO and SOLAS approvals.
The LT‑3100S Iridium GMDSS System is a cutting‑edge satellite communications terminal engineered to meet the most demanding maritime safety standards. As the first system to offer truly global GMDSS coverage (Sea Areas A1–A4) on the Iridium® satellite network, it provides mariners with reliable and continuous safety communication anywhere in the world.
Built for professional maritime operations, the LT‑3100S integrates all the essential Global Maritime Distress and Safety System (GMDSS) services including Distress Alert, Distress Call, Safety Voice, and Maritime Safety Information (MSI). These services ensure that distress and safety messages can be sent and received from any location, including remote polar regions traditionally unreachable by other satellite systems.
In addition to GMDSS safety services, the system supports standard Iridium communication features such as voice calls, SMS messaging, modem data services, vessel tracking, and non‑priority data. These capabilities make the LT‑3100S not only a safety terminal but also a comprehensive communication solution for vessels at sea.
Installation and integration are simplified through a single coaxial cable connecting the control unit to the antenna, allowing up to 500 m of separation between units for flexible antenna placement and optimal satellite reception.
The system is approved under international maritime safety standards, including those set by the IMO, SOLAS, MED Module B+D and Wheelmark, ensuring compliance across multiple regulatory environments. With rugged marine‑grade construction and a wide operating temperature range, the LT‑3100S is reliable and durable for professional use at sea.
