ZeratronZeratron Technologies / Passive RF sensing
Every drone speaks before it arrives.
We build passive RF systems that hear, classify, and locate the signals already in the air—without adding an emission of their own.
System monitoring / live01 / The premise
Detection does not need to announce itself. Zeratron turns the RF environment into operational awareness—from first signal acquisition to a usable bearing.
System capabilities
An engineered chain, not a black box.
Wideband sensing
Watch the spectrum with enough fidelity to find signal structure inside the noise floor.
02 / UnderstandSignal intelligence
Separate meaningful transmitters from the dense, ordinary activity around them.
03 / ActOperator-ready output
Turn acquisition into a bearing and a decision without requiring a permanent network.
02 / In development
Counter UAS, built around silence.
Our first system is a portable passive receiver for uncrewed aircraft. It works on the signals an aircraft and its controller already need to exchange.
