LT-3100S GMDSS System

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).

PERFORMANCE
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.

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).

INSTALLATION
The LT-3100S GMDSS system is very easy to install. Everything is included in the box to get started with the installation and operating the LT-3100S GMDSS system. The control unit can be installed using either a bracket mount or flush mount. The antenna unit can be mounted using either a pole mount (1.5″ tube) or angle bracket mount (1″ to 2.5″ tube). The control unit has a large 4.3″ TFT display, from where the system can be operated with overview and ease. The built-in webserver can be used for service and maintenance.

More than 40 years of experience have been put into the design and construction of the LT-3100S GMDSS system, with an exceptional performance and specification level.
