Iridium Communications

Iridium Communications owns and operates a constellation of 66 cross-linked low Earth orbit satellites providing voice and data services across the entire planet. The system utilizes L-band spectrum and intersatellite links to route data between spacecraft without requiring local ground infrastructure, enabling communication in polar regions, oceans, and airways. The company's primary infrastructure includes the Iridium NEXT constellation, completed in 2019, and the Satellite Network Operations Center in Leesburg, Virginia. Its core technology platform, Iridium Certus, supports multi-bandwidth applications ranging from narrowband IoT and Short Burst Data to high-speed broadband and the Global Maritime Distress and Safety System.

Iridium operates a wholesale business model, providing services through a network of approximately 500 value-added partners across maritime, aviation, and government sectors. In 2024, the company acquired Satelles, Inc., integrating the Iridium PNT service to provide satellite-based position, navigation, and timing that complements GNSS systems. The company is developing Iridium NTN Direct to enable satellite-to-device connectivity via industry-standard protocols. Iridium is public on NASDAQ (IRDM) and maintains 10-year service contracts with the U.S. Space Force while serving as a subcontractor for the Space Development Agency's Proliferated Warfighter Space Architecture ground segment.
