The company's constellation of 66 active low Earth orbit satellites, supported by 14 in-orbit spares, uses inter-satellite links to route communications without relying on ground stations, enabling truly pole-to-pole coverage. As of December 31, 2025, Iridium reported a trailing 12-month revenue of $872 million.\n\nIridium's customer base spans government and defense, maritime, aviation, land mobile, and IoT segments. The company provides satellite phones and personal communicators, broadband terminals for ships and aircraft, and low-cost IoT modules for asset tracking, environmental monitoring, and remote sensing. The U.S. Department of Defense is one of Iridium's largest customers through its EMSS (Enhanced Mobile Satellite Services) contract.\n\nIridium launched its second-generation Iridium NEXT constellation between 2017 and 2019 at a cost of approximately $3 billion, providing higher throughput broadband via Iridium Certus, a multi-service platform offering speeds up to 704 Kbps. While not competitive with Starlink for bandwidth, Iridium's unique global coverage, polar reliability, and small device form factor make it irreplaceable for aviation, maritime, and government users in remote areas. ## Frequently Asked Questions ### What makes Iridium unique among satellite operators? Iridium is the only satellite operator with true global coverage including both poles, achieved via 66 LEO satellites with inter-satellite links that route communications without needing ground stations nearby. ### What is Iridium Certus? Iridium Certus is Iridium's multi-service broadband platform offering voice, data, and IoT services via compact terminals for maritime, aviation, and land mobile users at speeds up to 704 Kbps. ### Who are Iridium's main customers? Iridium's key customers include the U.S. Department of Defense (via EMSS contract), maritime operators, airlines, oil and gas field services, emergency responders, and IoT device manufacturers needing global data connectivity. ### What is Iridium and what satellite connectivity does it provide? Iridium is a global satellite communications company operating a unique low-Earth orbit (LEO) constellation of 66 active satellites that provides voice and data communications coverage across the entire globe — including the poles, oceans, and remote regions where terrestrial cellular and other satellite systems do not reach. ### What makes Iridium's satellite constellation unique? Iridium's LEO constellation provides true pole-to-pole global coverage with satellites that inter-link in orbit, routing communications between satellites without requiring ground station relay in most cases — unlike geostationary satellite systems that have coverage gaps at high latitudes and higher latency due to their distance from Earth. ### What industries rely on Iridium for connectivity? Iridium serves maritime shipping, commercial aviation, military and government, oil and gas exploration, emergency response, remote research operations, and individual outdoor adventurers and travelers who require reliable communications beyond the reach of cellular and terrestrial networks. ### What is Iridium Certus? Iridium Certus is Iridium's broadband service platform that enables higher data rate applications for maritime, aviation, and land mobile users, supporting L-band satellite broadband connectivity for IoT, remote monitoring, and real-time operational applications in addition to voice communications. ### How does Iridium differ from newer LEO constellations like Starlink? Iridium's established 66-satellite constellation provides reliable global coverage and voice services with devices designed for reliability and durability in extreme environments, while newer LEO systems like Starlink use much larger constellations to deliver higher bandwidth internet access, targeting different use cases and customer types. ## Tags telecom, global, enterprise, public, north-america, b2b, infrastructure, hardware, iot, technology --- *Data from geo.sig.ai Brand Intelligence Database.
