Overview

Everywhere under one sky

In a world where global communications are increasingly critical, only one company connects everyone to the things that matter most, from pole to pole.

Powered by a uniquely sophisticated global constellation of 66 cross-linked Low Earth Orbit (LEO) satellites, the Iridium® network provides high-quality voice and data connections over the planet’s entire surface, including across oceans, airways and polar regions.

SATELLITE CONSTELLATION

A uniquely sophisticated architecture

Iridium operates the world’s largest commercial constellation, with a mesh architecture of 66 cross-linked low Earth orbit (LEO) satellites providing inherent performance and dependability advantages over bent pipe geostationary (GEO) configurations.

The low Earth orbit advantage

At only 476 miles (780 km) 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.

Unaffected by local conditions,
such as natural disasters

In space, each Iridium® satellite is linked to up to four others — two in the same orbital plane and one in each adjacent plane — creating a dynamic network that routes traffic among satellites to ensure global coverage, even when traditional local systems are unavailable.
