DESCRIPTION

EMSS provides deployed warfighters and partnering agencies with global communications through security and user prioritization enhancements to commercial Mobile Satellite Services (MSS). EMSS includes global handheld voice, data, paging, and sim-less Short Burst Data (SBD) communications.

EMSS is a capability provided by DoD that features global data transfer and securable voice communications. The service allows real-time access to other EMSS users, the SBU Voice and commercial U.S. and international telephone networks through the Iridium satellite network.

EMSS also offers the Distributed Tactical Communication System (DTCS), which is a secure tactical hand-held satellite radio that provides on-the-move, over-the-horizon, beyond line-of-sight, voice, position location information and narrow band data communications to disadvantage users in austere environments.   

FEATURES

  • Secure Voice — Encrypts voice communications using National Security Agency (NSA) Type-1 devices.
  • Prioritization — Mission partners can allow or deny access to the service in the event of a national emergency.
  • Basic Telephony — Mission partners can place or receive a secure call.
  • Circuit-Switched Data — Provides mission partners with a means of communicating (e.g., transmitting and receiving) high-capacity data with data terminal equipment.
  • Sim-less SBD — Provides a non-circuit-switched high-capacity means of transmitting and receiving packets of data to and from compatible SBD subscriber devices, sending and receiving short data, which is mainly used for asset tracking and remote monitoring. 
  • Paging — Mission partners can receive numeric or text pages.
  • Router Unrestricted Digital Information Connectivity Solution (RUDICS/Apollo) — Custom devices in the field may connect to servers on the SBU IP Data and provides no additional service logic beyond a transport pipe by which to transmit mission partner data.
  • Netted Communication — Using DTCS, allows users to communicate within a group, but prohibits outsiders from accessing the cmmunications.

Security Classification Up to and including Top Secret (TS)
Value to Our Mission Partners The EMSS handsets (satellite phones) enable the warfighter to communicate with the SBU Voice, Public Switched Telephone Network (PSTN) and SBU IP Data services by leveraging the EMSS gateway that interfaces with those services.
