"Making connections anywhere to anyone or anything, there is no other network like Iridium."

Reliability Above All®

Iridium’s crosslinked mesh architecture creates a web of coverage encompassing 100% of the planet from Low-Earth Orbit, providing low-latency, weather resilient services unlike any other satellite provider. No other network matches the reach, coverage, and reliability of Iridium.

With communications solutions ranging from satellite phones to broadband services, Iridium is trusted by more than 1.5 million mariners, pilots, humanitarians, first responders, governments, and more around the world.

In a world where global communications are increasingly essential, only one company connects everyone to the things that matter most, from pole to pole. Iridium keeps people – and things – connected on the land, in the air, or at sea.

More about Iridium

At only 780 kilometers from the Earth, the proximity of Iridium’s LEO network means pole-to-pole coverage, a shorter transmission path, stronger signals, lower latency, and shorter registration time than with GEO satellites. In space, each Iridium® satellite is linked to up to four others creating a dynamic network that routes traffic among satellites to ensure global coverage, even where traditional networks are unavailable.

Iridium’s global constellation is supported by an extensive ground infrastructure that ensures the high reliability and capacity of the communications network through multiple layers of redundancy and back-up systems for all critical functions.

Interconnected by advanced fiber-optic and broadband satellite links, the Iridium ground infrastructure consists of the Satellite Network Operating Center (SNOC), Ground Stations, and Technical Support Center, which together provide terrestrial connections for mobile satellite voice and data; network command, control, and monitoring; and technical support.

Iridium completed a multi-year constellation upgrade in early 2019, replacing all of its first-generation satellites and upgrading the supporting ground infrastructure. The new network has enabled new, faster, and more reliable service across global maritime, aviation, land, and government markets. The original Iridium constellation was launched in the late 1990s and completed approximately 100,000 orbits of Earth before being sustainably de-orbited as part of the replacement program.
