AEGIS is a multi-modal counter-UAS detection system that fuses acoustic, visual, and passive RF sensors to detect, classify, and alert on drone threats—starting at $315 per node. That's 100× cheaper than incumbents.

Autonomous Embedded Guardian for Integrated Surveillance

Why AEGIS

Counter-UAS that actually scales

DroneShield costs $50K+. Dedrone costs $100K+. Robin Radar costs $200K+. AEGIS starts at $315. Deploy ten nodes for the price of one competitor unit.

Three sensors, one picture

Acoustic detects the drone. Camera confirms it visually. Passive RF picks up the control link. Three independent modalities, fused into a single high-confidence track.

Works RF-denied

Acoustic detection is unjammable. You can spoof RF, jam GPS, and blind radar—but you can't silence propellers. AEGIS keeps working when everything else goes dark.

$315 per node

COTS hardware. Jetson Orin Nano, USB mic array, camera. A full perimeter defense for less than a single competitor sensor unit. Deploy 50 nodes for the cost of one DroneShield.

ATAK native

Detections push as Cursor on Target messages into the TAK ecosystem. Every operator with ATAK sees drone tracks in real-time. No custom apps, no integration work.

60-second deploy

Power on, wait for boot, operational. No installation crew, no calibration, no site survey. One person deploys a node in under a minute.

Mesh networked

Multiple AEGIS nodes share detections across a mesh network. Distributed coverage, triangulated bearings, and no single point of failure.

Sensor Stack

Three modalities. One fused picture.

Counter-UAS sensor modules — RF antenna, acoustic array, and PTZ camera

Acoustic Detection

Primary sensor. Always on. USB MEMS mic array captures audio, converts to mel-spectrograms, and runs through a MobileNetV2 CNN for real-time drone classification.

  • 100–300m detection range
  • 85–95% classification accuracy
  • Direction of arrival estimation
  • Multi-rotor vs fixed-wing discrimination
  • Known drone fingerprinting (DJI, custom)
  • Unjammable — works RF-denied

Hardware: $35 mic array

Visual Confirmation

Secondary sensor, cued by acoustic bearing. Gimbal auto-slews to the acoustic detection, YOLO11n identifies and classifies the drone visually.

  • 50–500m visual range
  • YOLO11n with drone-specific training
  • NanoTrack persistent tracking
  • FLIR Lepton 3.5 thermal (night ops)
  • Auto slew-to-acoustic-bearing
  • Day/night auto-switching

Hardware: $30 camera + $50 gimbal

Passive RF (Vantage)

Optional third modality via Ceradon’s Vantage platform. Detects drone control link RF signatures without emitting. Also detects ground-level operators.

  • Up to 500m C2 link detection
  • Zero RF emissions (covert)
  • Drone pilot/operator localization
  • Cross-correlates with acoustic
  • WiFi CSI subcarrier analysis
  • Complements high-noise environments

Hardware: Vantage node

Sensor Fusion

How detection works

Radar tracking display showing drone detection and tracking
1

Acoustic Cue

Mic array detects drone audio signature. CNN classifies type. GCC-PHAT estimates bearing. Alert level: YELLOW.

2

Visual Confirm

Gimbal slews to acoustic bearing. Camera acquires visual. YOLO11n confirms drone. NanoTrack locks. Alert level: ORANGE.

3

Fused Track

All sensors correlated. High-confidence classified track pushed to ATAK. Operator alerted. Alert level: RED.

Competitive Landscape

How AEGIS compares

Robin Radar $200K+
Applications

Who uses AEGIS

🛡️ Forward Operating Bases

Perimeter C-UAS coverage for FOBs and patrol bases. Deploy multiple nodes for 360° acoustic coverage. ATAK integration means every operator on the net sees drone tracks.

👮 Law Enforcement

Event security, prison perimeter protection, critical infrastructure monitoring. Affordable enough for every precinct, not just federal agencies.

🏭 Critical Infrastructure

Power plants, water treatment, data centers, airports. Persistent drone surveillance at a cost that scales to hundreds of sites.

⚔️ Special Operations

Lightweight, man-portable C-UAS for austere environments. Acoustic-first detection works when adversaries jam GPS and RF. Pairs with RAPTOR for detect-to-engage kill chain.
