Modular, vehicle-mounted passive drone detection

Wherever you are.
Whoever you are.
Whenever you need it.

Greywing builds passive drone detection systems that mount directly onto any vehicle. The systems detect FPV drones, including fibre-optic drones, then act.

The problem

Detection has largely meant finding the radio link between drone and operator. Fibre-optic FPVs removed that link, and the drones still hit convoys, logistics trucks, aid transport and civilian traffic. The systems that can find them by other means are mostly built for fixed sites or large platforms, at prices no single vehicle can justify.

GW-VNR1

Acoustic Early Warning Set

Designed to hear drones in every direction and warn the crew.

  • Audible and on-screen alert
  • Direction and confidence
  • Runs on vehicle power, no network

GW-VSR1

Acoustic-Visual Detection Set

GW-VNR1 plus a camera commanded by the acoustic array. Designed for engagement systems integration.

  • Visual confirmation of each alert
  • Identification of the object in view
  • Recorded imagery of each detection

GW-VSR1 signal chain. A microphone array feeds spectral analysis, which forks into two parallel branches, classification and bearing estimate. Classification produces an early alert, and together with the bearing estimate feeds visual confirmation, which produces the confirmed alert. An optional path passes the confirmed alert on to external systems.

Microphone array: listens continuously in every direction.
