Lars Thrane A/S LT-3100 Satellite Communications System

Overview

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 for worldwide maritime satellite communication equipment.

Performance

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 and cradle. 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 terms of 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 the perfect satellite communication product on board any vessel.

The LT-3100 Satellite Communications System is designed and built for the demanding and rough environment at sea and with an operational temperature range from -25⁰C to +55⁰C (-13⁰F to +131⁰F).

Installation

The LT-3100 system is very easy to install and requires no yearly maintenance or service. Everything is included in the box to get started with the installation and operating the LT-3100 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 bracket mount (1″ to 2.5″ tube). The control unit has a large 4.3″ TFT-LCD 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-3100 Satellite Communications System, with an exceptional performance and specification level.
