LT-3100S GMDSS System
GMDSS with combined Voice, Data and Tracking
The LT-3100S GMDSS system offers both voice and data capabilities in addition to certified GMDSS function with 100% global service. Iridium’s NEXT constellation provides this terminal with unparalleled A4 coverage for satellite safety services.
The system consists of a control unit, handset and antenna. A single cable solution connects the control unit with the antenna unit. Using a standard coaxial cable, the antenna and control unit can be positioned up to 500m apart, giving the freedom to mount the antenna in the best possible location for line of sight to the satellite.
A powerful yet compact communications platform
In addition to providing a GMDSS solution the LT3100S can be used as the primary satellite communication solution on vessels, covering the basic communication needs in terms of connectivity between the ship and shore. The small form factor of the unit means that that it can be easily utilised on smaller vessels or be fitted into an existing bridge solution without the space requirement consideration of a traditional console GMDSS system.
The system provides safety voice, standard voice, SMS, IP data and other Iridium services with the only truly global network, making it the perfect satellite communication product on board any vessel. It also offers SSAS and LRIT functionalities. An optional control box can also be added, the LT-3140S, giving the possibility of connecting both dedicated alert panels & printer for the system as well as integration with bridge management systems.
The LT-3100S GMDSS System is designed and built for the demanding and harsh maritime environment with a large operational temperature range and an immersion ingress protected antenna.
In addition to its rugged design, the system can be customized to suit your specific communication needs. The option to connect to use SIP or POTS phones (via an adapter), a built-in webserver for easy configuration and maintenance and the facility to use Bluetooth for a private area network all enhance this compact system for use as your primary solution on board.
