CI System's Missile Signal Simulator – Long Range (MSS-LR) is a compact hand-held and self-contained missile engine radiation plume simulator. The MSS-LR enables the operator to test the readiness and performance of Missile Warning System (MWS) in the flight line as a routine test or close to takeoff as well as in the laboratory. The MSS-LR is designed to MIL standard requirements to withstand field environment conditions. The MSS-LR offers extended simulation range for systems requiring a testing distance greater then 3 meters.
