Early warning against attack drones
Falkonis Nest hears Shahed-class and even jet-powered attack drones kilometres away, recognises them with AI running on the node, and alerts your phone in seconds. It emits nothing while it listens, so the drone has nothing to find.
The engine of an attack drone leaves a ladder of tones that carries for kilometres, and a jet is louder still. The model on the node picks it out of wind and traffic. There is no audio stream and no cloud round-trip.
One short cellular message, with the node’s position, to a phone or a command platform. Apart from a brief status check-in, that is all Falkonis Nest ever puts on the air.
The problem
One-way attack drones fly low, at night and in numbers. Radar picks them up late or not at all, and every interceptor fired costs more than the drone it brings down.
Most borders, energy sites and towns don't need another interceptor. They need a few minutes' notice, everywhere along the route, all the time. That is what Falkonis builds: a dense, cheap, silent listening network that tells you something is coming while there is still time to act.
A microphone behind the nest-box entrance hole listens to the sky day and night. The engine of an attack drone carries for kilometres.
AI on the node tells a war drone’s engine apart from tractors, cars, chainsaws and wind. Nothing is streamed, nothing leaves the node.
Seconds later a short cellular message with the node’s position reaches a phone or a command post. The radio is off the rest of the time.
3+km design range
Against Shahed-class drones. Jet-powered drones are louder still.
0W radiated
The node only listens. Its radio wakes up only to report.
90+days autonomy
On battery and solar, through a Baltic winter, with no visits.
What it hears
Nest is tuned to the engines that matter: the drones sent against cities, power grids and positions.
Long-range one-way attack drones with piston engines and pusher propellers produce a loud, harmonic engine note. Nest is designed to hear it from more than three kilometres away.
Jet-powered attack drones fly faster and are louder still. A turbojet cannot be muffled, and Nest is designed to hear these too, so the faster threat is announced earlier.
Pre-programmed routes and satellite navigation leave nothing on the radio spectrum to intercept. The engine still runs, and that is what Nest listens for.
The product
An early-warning node that looks like a bird box. It hangs on a tree, mast or pole, charges itself from the sun and listens to the sky around the clock. When a war drone passes it raises the alarm, and otherwise it stays silent.
Nodes are spaced every few kilometres along a border or around a site, and every node reports into one map. One person installs a node in minutes with two straps and a ladder.
Who it is for
A listening fence along a border or around a position that keeps working without power, masts or crews.
Substations, refineries, depots, airports and ports, which are the targets attack drones are sent against.
Minutes of notice feed directly into sirens and alerts for the communities under the flight path.
Approach
Attack drones fly low under radar coverage, and are cheap enough to be sent in swarms. Acoustic sensing works at exactly the altitudes where radar struggles.
A radar announces itself the moment it is switched on. A microphone gives an adversary nothing to home in on, and the node’s radio stays off until it has something to report.
Solar-powered nest boxes that need no mains, masts or crews. A whole line of nodes costs less than a single interceptor.
We are preparing the first field deployments with defence, border and critical infrastructure operators. Tell us what you need to protect, and we will show you what Nest hears.
