ISR System
SEMS (Space Electro Magnetic Surveillance) represents the modern way of implementing the ISR (Intelligence, Surveillance, Reconnaissance) function. SEMS is composed of one advanced ELINT payload (SEMS-PL) and one SEMS Ground Station (SEMS-GS). SEMS-GS, by receiving data from SEMS-PL, provides accurate analysis and geo-location of ground emitters intercepted from Space.
