SMC plans to purchase two additional EPS EHF XDR payloads to prevent a MILSATCOMmission gap in the Polar region. SMC is pursuing a near-term hosted payloadoption to be launched in Calendar Year (CY) 2022 to satisfy EPS missionrequirements...Global protected SATCOM will be provided in the near-term by two complementary space systems. The Advanced Extremely High Frequency (AEHF) system currently provides protected SATCOM services for both tactical and strategic users inmid-latitude regions (65°S to 65°N). The EPS will soon provide protected SATCOMfor a small number of tactical users in the North Polar Region (65°N to 90°N).ngBoth AEHF and EPS provide protected SATCOM employing XDR payloads utilizing theEHF band.EPS payloads are currently hosted on another organization's space vehicle. EPS-1is currently on orbit and EPS-2 will be available for testing in late CY17. TheEPS ground segments includes a payload control and mission planning elementlocated at Schriever AFB and a Northern Tier SATCOM Gateway located at Clear AFS,which provides DoD Information Network (DoDIN) connectivity via the Camp RobertsTeleport.
