Enhanced Polar System (EPS)
Abstract:
The Enhanced Polar System EPS provides continuous protected communication low probability of interception and detection over the north polar region using two communications payloads on classified host satellites in highly elliptical Molniya orbits. EPS is composed of four segments the eXtended Data Rate XDR Payload integrated onto a classified host, the User Terminals acquired separately by the users, the Gateway a fixed installation, and the Control and Planning Segment CAPS another fixed installation. The Payload segment provides protected Extremely High Frequency communications in the north polar region. The Terminal segment provides the communication link to the EPS users. The Gateway segment provides connectivity between the north polar users and the mid-latitude users via the Defense Information System Network Global Information Grid. CAPS acts as the Satellite Operations Center with command and control, mission and crypto planning, test and sustainment, training, ephemeris, and key distribution workload.
