System overview

Three steps.
Complete protection.

Each CTA-100 is a self-contained sensor — phased microphone array, onboard DSP, and encrypted mesh radio. No cables, no base station, no cloud.

01 — DEPLOY

Deploy at every asset

Mount a CTA-100 on each vehicle, tent, or static asset. Nodes auto-discover each other via encrypted LoRa mesh — no IP, no Wi-Fi, no operator configuration required. Operational in 8 minutes from unboxing.

02 — DETECT

Passive acoustic detection

8 MEMS microphones run real-time SRP-PHAT beamforming. The array resolves drone blade-pass frequency against background noise with ±2° angular accuracy. Zero RF emissions — the sensor is invisible to adversary EW.

03 — TRIANGULATE

GPS-quality localization

Each node broadcasts its bearing to the mesh. Three or more overlapping nodes compute a GPS coordinate for the threat in under one second. No single point of failure — any node can anchor the triangulation.

Deployment scenarios

Built for the field.

CTA-100 nodes adapt to any tactical configuration. Each asset carries its own sensor — the mesh does the rest.

Scenario 01

Forward Operating Base

Attach nodes to every vehicle, tent, and static asset within the FOB perimeter. Optionally deploy a second ring of standalone nodes at 200–400m radius for layered early warning. The system instantly shows monitored vs. unmonitored airspace on the command display.

8–16 camp nodes 0–8 perimeter nodes LoRa mesh 8 min setup
Scenario 02

Critical Infrastructure

Perimeter ring deployment around power stations, fuel depots, bridges, and communications sites. Nodes self-organize into a mesh with no central controller. A single CTA-100 failure doesn't degrade coverage — neighboring nodes absorb the bearing load.

12–32 perimeter nodes Tripod / wall mount Solar optional Indefinite uptime
Scenario 03

Convoy Protection

Vehicle-mounted nodes form a rolling acoustic mesh that moves with the convoy. Each vehicle's node detects independently and relays bearings to the lead vehicle. No fixed infrastructure, no GPS dependency for detection — the mesh triangulates on the move.
