Connect Globally with Iridium

Introduction to Iridium

Iridium is the only satellite communications company that provides a truly global connection. Whether it be connecting via remote land areas, air, across oceans, and even the polar regions, Iridium is the most far-reaching satellite communications service available.

How is it that Iridium can be so powerful and provide this kind of unmatched connectivity? Through a global constellation of 66 cross-linked Low Earth Orbit (LEO) satellites, high-quality voice and data connectivity is possible pole-to-pole. The LEO satellites allow for a shorter transmission path and lower latency with stronger signals. In short, it’s everything you ever hoped for in remote connectivity.

Iridium understands the need for a reliable network, anytime and anywhere.* Today, voice and data communication is a lifeline – both as a connection we value when family members are far away, or quite literally the critical connection we rely on in matters of life and death.

As of 2019, the Iridium network became even stronger with the rollout of Iridium Certus.

Iridium Certus

The newly architectured Iridium Certus will bring you whatever you require in functionality without compromising speed. Satellite communications have been upgraded to one multi-faceted platform with the highest throughput L-band data connection available. With Iridium Certus comes fast, reliable, unparalleled global connectivity. You can expect:

  • streaming data
  • high-quality voice service
  • data broadcast
  • safety services

Allowing individuals, mega-sized operations, (and everything in between) to communicate and run their global business from afar, Iridium offers this all at a superior value. Whether your needs involve short burst data, openport, voice, or a specific maritime solution, the following products will connect you through the most reliable mobile satellite communications network in the world – Iridium.

Short Burst Data (SBD)

Simplicity and efficiency is what you will get with Iridium’s short burst data options.  The short burst data service of Iridium sends and receives short voice and data messages between field equipment and a central host computing system. Machine-to-Machine (M2M) connectivity, as well as Telemetry and Tracking applications,  run smoothly through a complete SBD architectured system with an Iridium subscriber unit or transceiver such as the 9522B Transceiver.

OpenPort Broadband

Look no further for greater reliability and stronger throughput than the affordable Iridium Broadband solution. This OpenPort service provides the communication capability to quickly send and receive email, browse the web and make high-quality voice calls. Does your vessel require a reliable VSAT back-up solution? Iridium’s OpenPort products, such as the Iridium Pilot Marine Terminal, allow for this critical connectivity. Easily installed, it can perform all functions in any weather conditions and anywhere on the planet.


The Thales VesselLINK is a military-grade device that runs on the global Iridium Certus network. It is equipped to handle any sea conditions pole-to-pole. With its reliable functionality and top of the line safety features, the Thales VesselLink is a perfect communications solution for a single vessel or the most extensive fleet. This product is user-friendly and provides basic necessities such as messaging, voice and e-mail. Additionally, it is versatile and powerful by offering uninterrupted coverage for elite naval operations around the world. Create a complete, globally connected vessel by integrating this device with your current equipment.


Maintaining phone call capability worldwide has become a necessity for people traveling to remote destinations by land, air, and sea. Iridium created a unique network that allows customers to never be without phone service ever again. The Iridium 9555 is one product that allows for global mobile communications via satellite. Trust that your product will work with reliable connectivity is paramount, and this phone (which includes a hands-free headset) delivers. It is ruggedly built to withstand the elements. Though powerful and robust, it is more lightweight than its predecessor while still being the dependable lifeline you depend on.
