Iridium Global Network

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.

Unparalleled Reach and High Dependability #

For customers, the unparalleled coverage and high dependability of the Iridium network means they can rely on their critical communication lifelines to work when they need them most — anywhere.

Push-to-Talk the Way it Was Meant to Be

Iridium Extreme PTT is the world's first ever truly global push-to-talk device. Powered by the Iridium Push-to-Talk service, it combines fast, simple and secure group communications with the power of the toughest, most feature-rich satellite phone ever.

Reliability Above All #

In early 2019, Iridium completed the $3 billion Iridium NEXT mission, which completely replaced the first-generation Iridium constellation. With an upgraded network, Iridium is poised now more than ever to meet the growing demand for global communications on land, at sea, and in the skies – far into the future.

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.
