In 2018, the IMO’s Maritime Safety Committee (MSC) recognized Iridium as a provider of GMDSS satellite services. Throughout the intervening period, Iridium has run 13k + service tests and onboard terminal assurance via the LT-3100S GMDSS system, a integrated terminal developed by Lars Thrane A/S.
As of December 2020, Iridium GMDSS Service is LIVE and fully functional.
The Lars Thrane LT-3100S Iridium GMDSS system is designed for all IMO vessels and is an alternative to the Inmarsat C GMDSS Solution. The LT-3100S GMDSS system meets all standards and certification requirements needed for worldwide maritime satellite communications equipment (MED, Wheelmark).
The LT-3100S GMDSS system has voice and data capabilities with 100% global coverage. The LT-3100S GMDSS system consists of a control unit, handset, and antenna unit. A single cable solution connects the control unit with the antenna unit. Using a standard coaxial cable, up to 500 meters of separation between the units can be obtained, giving freedom to mount the antenna in the best possible location, with free line of sight to the satellites.
The LT-3100S GMDSS system is designed for the Iridium GMDSS Safety Services and can be used as the primary satellite communication product on vessels, covering the basic communication needs in terms of connectivity between the ship and shore. The LT-3100S GMDSS system also provides voice, SMS, data, vessel tracking, and other Iridium services with competitive airtime rates, making it the perfect satellite communication product on board any vessel.
