LT-4100 Iridium Certus 100

The LT-4100 is a maritime satellite communications system built on the Iridium Certus® 100 service. Engineered for deep-sea vessels, fishing fleets, and workboats — and equally suited to leisure craft — it delivers reliable global connectivity while meeting all international standards and certification requirements for maritime satellite equipment. A LandMobile variant, the LT-4100L, brings the same capability to vehicles and remote installations ashore.

Designed to serve as a vessel’s primary communications hub, the LT-4100 provides 100% global coverage through the Iridium® network. The system combines a control unit, antenna unit, handset, and cradle — linked by a single coaxial cable that allows up to 500 metres of separation. This flexible design ensures the antenna can always be placed in the optimal position, with a clear view of the sky.

With two high-quality voice channels and IP data of 22 kbps up / 88 kbps down, the LT-4100 keeps ship-to-ship and ship-to-shore communication straightforward and dependable. Built to endure the harsh realities of maritime life, it operates reliably from –40°C to +55°C, ensuring performance in even the toughest conditions.

Supplied with all essential components, it offers multiple mounting options — bracket or flush for the control unit, and 1.5″ or 2.0″ pole mounts for the antenna. Once installed, the large 4.3″ TFT display provides clear day-and-night visibility, while the intuitive interface gives full control at a glance. For service and maintenance, the integrated webserver makes configuration and updates simple and efficient.
