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.
LARGEST SATELLITE CONSTELLATION
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.
Iridium’s global constellation is supported by a recently upgraded, extensive ground infrastructure that ensures the high reliability and capacity of the communications network through multiple layers of redundancy and back-up systems for all critical functions.
Interconnected by advanced fiber-optic and broadband satellite links, the Iridium® ground infrastructure consists of the Satellite Network Operating Center (SNOC), Ground Stations and Technical Support Center, which together provide Terrestrial connections for mobile satellite voice and data Network command, control and monitoring, and Technical support.
