Iridium Communications Inc.

Iridium Communications Inc. is a publicly traded American company headquartered in McLean, Virginia, United States. It stands as the sole commercial provider of voice, data, and positioning, navigation, and timing (PNT) satellite services with true global coverage. The company's core mission is to enable real-time connections for people, organizations, and assets anywhere on Earth, particularly in remote regions where terrestrial networks are limited or unavailable.

Iridium operates a robust constellation of 66 active low-Earth orbit (LEO) satellites, supported by in-orbit spares, to deliver reliable and weather-resilient communication services. Its comprehensive portfolio includes mobile voice and data communications, satellite-based Internet of Things (IoT) services, broadband terminals, and specialized solutions. These services cater to diverse market segments such as maritime, aviation, government (including the U.S. Department of Defense), emergency services, mining, forestry, oil and gas, heavy equipment, transportation, and utilities.

In a strategic move in 2024, Iridium acquired Satelles, Inc., a leader in secure satellite-based time and location services, significantly bolstering its PNT capabilities to complement and safeguard GPS and other Global Navigation Satellite Systems (GNSS). The company is also at the forefront of innovation with Project Stardust, or Iridium NTN Direct, a 3GPP standard-based satellite-to-cellphone service for messaging, emergency communications, and IoT, anticipated to launch in 2026. Matthew J. Desch leads the company as CEO. Iridium maintains a strong market position as the only truly global mobile voice and data satellite communications network, having surpassed 2.5 million subscribers by late 2025.
