Congratulations on your purchase of the LT-4100 Satellite Communications system - Iridium Certus® 100!
The LT-4100 Satellite Communications System is a maritime satellite communication product from Lars
Thrane A/S. The LT-4100 system is designed for the professional market (deep sea, fishing, and workboats),
but can be used for the leisure market as well. The LT-4100 system meets all standards and certification
requirements needed for worldwide maritime satellite communication equipment.
The LT-4100 system has voice and data capabilities with 100% global coverage provided by the Iridium®
Communications Network. The LT-4100 system offers the following Iridium services:
•
2 x Voice Channels (high quality)
•
IP-data: 22 kbps (up) / 88 kbps (down)
The LT-4100 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 Iridium satellites.
The LT-4100 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 and ship to ship.
