Break the horizon! ERA launches its new Passive Long-range ESM Surveillance System PLESS

PLESS is a passive Over The Horizon (OTH) Direction Finding (DF) system developed by ERA. This direction finding system can detect, locate, identify and track air, land and naval targets with a focus on
slow-moving or stationary platforms. The system processes signals from radars, jammers and datalinks emitting in a frequency band from 100 MHz to 18 GHz. Using the unique passive detection technology by ERA, the PLESS
direction finding system provides a covert mode of operation, ideal for long-term cross-border and maritime surveillance. Thanks to the utilization of tropospheric reflectivity properties, the PLESS direction finding system can see targets located even beyond the radio horizon.
