CRFS comes from high-end spectrum monitoring. Its RFeye receivers passively detect and geolocate COTS, modified and military drones plus their operators via networked TDOA/AOA — no emissions of its own. Chosen by Rafael to enhance Drone Dome's RF layer. Strong at wide-area, multi-node spectrum surveillance.
