Iridium vs NTT
Side-by-side comparison of AI visibility scores, market position, and capabilities
Iridium (NASDAQ: IRDM), 66 LEO satellites providing truly global pole-to-pole coverage; $872M trailing revenue in 2025, serving IoT, maritime, aviation, and defense connectivity customers.
About
Iridium Communications Inc. is a publicly traded American satellite communications company headquartered in McLean, Virginia, operating the world's only truly global satellite network capable of providing voice and data coverage at every point on Earth including the poles. 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.
