Overview

Count on Iridium for tactical, real-time voice and low-latency data communications when it matters most. No other company can help mobilize and monitor personnel, data, and assets on the ground, beyond line-of-site, and out of reach of terrestrial networks – anywhere on the planet.

Enhanced Mobile Satellite Services (EMSS)

Iridium holds a multi-year, fixed-price contract with the United States Department of Defense (DoD), through the United States Space Force, enabling EMSS capabilities with unlimited usage for an unlimited number of subscribers on Iridium narrowband devices.
