Iridium Certus Ready

Yachts, sailboats, and other recreational boats can now benefit from the global connectivity, high-quality, and value of Iridium Certus. Now, leisure mariners can take advantage of Iridium Certus high-speed L-Band connectivity.

Why Choose Iridium Certus?


High-Speed L-Band Anywhere on Earth: Iridium Certus offers superior connectivity for maritime customers whether used as a standalone service or as a complement to VSAT services.

Product Diversity:  Iridium Certus offers a selection of service classes starting at 88Kbps and ranging up to 700Kbps, with eventual speeds to 1.4 Mbps.

Multi-Service: Iridium Certus customers will enjoy three high-definition voice lines, high-speed IP data and streaming, packet data service (Iridium Short Burst Data®), and safety services in one robust marine-grade terminal.

Highest Availability: L-Band is the lowest frequency commonly available for maritime satellite communications, meaning that the Iridium® signal can penetrate clouds, fog, and rain better than higher frequency Ka- and Ku- band signals.


Sophisticated Network: The low-Earth orbit Iridium constellation consists of six orbital planes with 11 satellites in each plane. Satellites provide connectivity as they fly “over” users anywhere on the planet.

Global Coverage: With coverage in the extreme latitudes and throughout the polar regions, Iridium provides a one-stop-shop for true global connectivity.

Rapid Routing: Iridium Certus routes traffic in space, ensuring that all areas, including the polar A4 zones, benefit from low-latency, high-speed, and always-on connections.


Redundant Design: The sophisticated Iridium network is a fully-meshed global canopy with high-speed cross-links designed to deliver uniform coverage and data speed to every point on earth.

Solid Equipment: Iridium Certus maritime terminals, designed and built by world-class manufacturers, have no moving parts, making them reliable and low-maintenance.

Robust Spectrum: Iridium’s L-band frequency is unaffected by weather conditions.


Iridium is committed to providing great features at a reasonable cost, and Iridium Certus has raised the bar for value. Iridium Certus provides greater performance than other L-Band options, and the Iridium Certus maritime terminals and airtime are available at competitive rates to allow for a fast return on investment. The small form-factor and lightweight equipment ensures ease of install and a streamlined upgrade path from existing service.
