Secure Satellite Communications for U.S. Government Users
Powering Secure Communications for Warfighters Worldwide
U.S. government users can take immediate advantage of unlimited voice and narrowband data for an unlimited number of subscribers through a multi-year contract between Iridium and the U.S. Space Force.
Key EMSS Benefits
Truly Global Coverage
Every pole, ocean, and battlefield.
Operational Security
All EMSS network traffic is routed through a dedicated, U.S. government-owned and operated service center.
Interoperable Access
Seamless communication across agencies and systems.
Unlimited Airtime & Devices
No per-minute or data limitations for authorized users and a wide selection of Iridium and Iridium Connected® equipment.
Autonomous Systems
Our network enables continuous beyond-line-of-sight (BLOS) operations in uncrewed air, sea, and land systems, leading to smarter, safer, and more efficient mission execution.
Iridium Certus®
Iridium Certus provides reliable broadband connectivity for voice, data, and video, even in denied, degraded, intermittent, or limited (DDIL) environments. With support for mobile and fixed terminals, it enables real-time situational awareness, command and control, and interoperability across air, land, sea, and space domains.
Secure Voice
The Iridium 9575A satellite phone delivers secure voice, email, and SMS communications anywhere in the world. When integrated with General Dynamics Sectéra® Iridium Security Module 2, the “Bearcat” supports NSA-certified Type 1 encryption, ensuring trusted, end-to-end secure field communications.
Mission Support Services
Enabling secure, global connectivity for defense, intelligence, and federal operations.
Enhanced Short Burst Data (ESBD)
Developed for government users, ESBD offers end-to-end transmission security (TRANSEC) and greater payload capacity for one- or two-way messaging than Iridium Short Burst Data® (SBD®). It's ideal for C2, remote monitoring/tracking, and unattended sensors.
Managed Access DNX (coming soon)
Our next-generation distributed tactical communications system (DTCS) will enable C2 in dynamic operational environments. MA-DNX seamlessly connects field and web-based users across dispersed locations, supporting mission success through secure, interoperable communications.
Iridium Burst®
Iridium Burst delivers high-power, one-way data to unlimited devices across targeted regions, even in challenging environments. It's suited for covert ops, autonomous systems, sensor control, and infil applications.
Connect Confidently. Operate Globally
Rely on Iridium’s proven, secure satellite communications network to keep your mission connected—anywhere on the planet.
