About
About Hidden Level
Hidden Level develops passive RF sensing networks for low-altitude airspace awareness. Its sensors detect aircraft and drone transmissions, estimate the operator's location and deliver the resulting tracks to monitoring teams.
Distributed deployments provide coverage without relying on a single radar installation, allowing public-safety, defence and critical-infrastructure operators to see activity across a wider area. Hidden Level's software turns radio-frequency observations into detection, geolocation and response data for ongoing airspace monitoring.
