The LT‑4200 Iridium Certus® 200 Satellite Communications System is a professional maritime satcom terminal delivering 100 % global coverage via the Iridium network. Designed for offshore, commercial, and leisure vessels, it supports three high‑quality voice channels and background IP data up to 176 kbps, with flexible installation using a single coaxial antenna cable (up to 150 m). Featuring a large 4.3″ TFT display, GNSS/GPS receiver, and Ethernet LAN interface, the LT‑4200 ensures reliable ship‑to‑ship and ship‑to‑shore communication in all sea conditions.
The LT‑4200 Iridium Certus 200 Satellite Communications System is a cutting‑edge maritime communication solution from Lars Thrane A/S that offers true global satellite coverage over the Iridium Certus network. Designed for professional use in demanding marine environments — including deep‑sea vessels, fishing boats, workboats, and leisure craft — this system meets all international standards for worldwide maritime communication equipment.
The LT‑4200 system provides three high‑quality voice channels and background IP data services with speeds up to 176 kbps (uplink and downlink), making it ideal as a primary communication terminal on board. These capabilities support voice calls, data transmission, internet connectivity, and basic maritime operational needs for vessels at sea.
Installation is simple and flexible thanks to a single coaxial antenna cable connecting the control unit with the antenna, allowing up to 150 meters of separation for optimal antenna placement with a clear satellite line of sight. The system includes a large 4.3″ TFT display supporting day and night modes, an Ethernet LAN interface for network connectivity, and a built‑in web server for configuration and system maintenance.
Additional features such as support for external SIP PABX and SIP handsets (up to 8), POTS connectivity via analogue telephone adapters (ATA), firewall and user authentication, and IP‑data management tools ensure secure and robust performance in demanding marine operations. With a high‑performance GNSS/GPS receiver onboard, the system also supports accurate positioning for tracking and navigational purposes.
Built to withstand harsh maritime conditions, the LT‑4200 operates across a wide temperature range and includes all necessary components for straightforward installation, making it a dependable global communication solution for modern vessels.
