EMSS is a satellite-based telephone and data communication service, utilizing a commercial satellite infrastructure to provide voice and low data rate services from a mobile, lightweight terminal through a Department of Defense (DoD) dedicated gateway which accesses the Defense Information System Network (DISN). It is capable of providing Type-1 secure voice service and non-secure access to commercial and DSN telephone services.

Modifications to the commercial system enable DoD to offer unique features such as end-to-end Type-1 voice encryption and protection of sensitive user information. DoD has established a dedicated Government EMSS gateway providing remote access to the Defense Switched Network (DSN), Commercial Long Distance, Commercial International Long Distance and the DISN.

  • Encryption – End-to-end, Type 1 Voice and Non-Secure Data capability
  • Signaling – Protection of sensitive user information

EMSS also provide the following special features: Broadcast Service, Protected Paging, Unclassified but Sensitive Internet Protocol Router Network (NIPRNet) Connectivity, Short Burst Messaging, Conference Calling and Secret Internet Protocol Router Network (SIPRNet) Connectivity (2008).

The commercially available Iridium 9505 terminal will support secure communications by adding a removable National Security Agency (NSA) approved Type I Communications Security (COMSEC) sleeve which fits onto the user terminal. EMSS is available as a service offering through DISA to DoD, other Federal departments and agencies, state and local governments, and Joint Staff (J-6) approved foreign and allied government users.
