PRODUCT DESCRIPTION
The LT-3100 Satellite Communications System is a maritime satellite
communication product from Lars Thrane A/S. The LT-3100 system
is designed for the professional market (deep sea, fishing, and workboats), but can be used for the leisure market as well. The LT-3100
system meets all standards and certification requirements needed forworldwide maritime satellite communication equipment.

100% GLOBAL COVERAGE

The LT-3100 system has voice and data capabilities with 100% global
coverage provided by the Iridium® Communications Network. The
LT-3100 system consists of a control unit, antenna unit, handset andcradle. A single coaxial cable 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
unit in the best possible location, with free line of sight to the satellites.
The LT-3100 system can be used as the primary satellite communication
product on vessels, covering the basic communication needs in termsof connectivity between the ship and shore. In addition, the LT-3100 system can be used for crew calling or as back-up satellite communication
product. The LT-3100 system provides voice, SMS, data, vessel tracking,and other Iridium services with competitive airtime rates, making it theperfect satellite communication product on board any vessel.
