Discovair G2+

Discovair G2+ is Squarehead Technology's passive acoustic drone-detection sensor: an array of 128 microphones with an integrated optical camera that detects, classifies and tracks class I and II drones by their sound, using machine-learning algorithms. It can be deployed in a 105° directional mode, with several sensors combined for 360° coverage, or mounted horizontally in a 360° hemispheric mode that covers the full surroundings with one sensor. Because it emits nothing, it keeps working in jammed or RF-denied environments and operates undetected. Its predecessor, the Discovair G2, was integrated with DroneShield's DroneSentry-C2 software in 2020, and in September 2026 UNIFY.C2 announced the integration of the Discovair G2+ into its command-and-control platform.
