The LT-3100 Satellite Communications System is a maritime fixed Iridium satellite phone from Lars Thrane A/S.
In 2018, the IMO’s Maritime Safety Committee (MSC) recognized Iridium as a provider of GMDSS satellite services.
In early 2020, these GMDSS services, hereunder: Distress Alert, Safety Voice, and Maritime Safety Information (MSI)
will be available via the LT-3100S GMDSS system, a terminal developed by Lars Thrane A/S.
The LT-3100S GMDSS system is designed for all IMO vessels and will be an alternative to the Inmarsat C.
The LT-3100S GMDSS system meets all standards and certification requirements needed for worldwide maritime satellite
communications equipment (MED, Wheelmark).
Thrane LT3100S
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 not only designed for GMDSS services. It also offers SSAS and LRIT functionalities.
It 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.
The LT-3100S GMDSS System is designed and built for the demanding and rough environment at sea and with an operational
temperature range from -40⁰C to +55⁰C (-40⁰F to +131⁰F).
