Turn off-the-shelf FPV drones into coordinated swarms.
Bolt-on leader-follower module for standard FPV airframes. UWB relative positioning, zero GNSS reliance, and modular interceptor integration for GPS-denied and jammed EW environments.
The Luftschar swarm module is a leader–follower unit that bolts onto existing FPV drones — no airframe redesign, no new aircraft. Attach it and the drones coordinate themselves: cheap, expendable airframes become a decentralised strike force that flies itself.
A short-range UWB network gives every drone its position within the formation with meter-level accuracy — independent of GNSS availability.
Followers track the leader through relative UWB measurements. Decentralised mission execution means there is no single point of failure to shoot down.
Swarm guidance keeps working when GPS is denied or degraded — precisely the condition in which most drone operations fail.

From single drone to swarm in four steps
The module closes the loop between cheap airframes and coordinated behaviour — each step works without GNSS.
Attach
Bolt the swarm module onto any existing FPV airframe. No redesign, no new drone — the airframes you already buy become swarm nodes.
Locate
The UWB mesh measures each drone's position relative to its neighbours — meter-level accuracy with no satellite lock required.
Follow
Leader–follower guidance holds formation geometry while the leader flies the mission profile; followers react to relative measurements, not absolute fixes.
Execute
Decentralised mission execution under GPS denial and EW pressure — a single-operator human-in-the-loop keeps the swarm on task.
From bench to battlefield — the goal chain
Every step is measured the same way, so what we prove in the lab is what flies in the field.
TRL 4 — simulation core + UWB bench
The swarm logic runs end-to-end in simulation, and a physical UWB bench reproduces the same behaviour on real hardware.
BraveTechEU DefTech Forges — application in
Application submitted to the 2nd edition of the BraveTechEU DefTech Forges call (EUR 120,000 prize per winning team). The swarm module is the product we are taking to the Forge.
Field-scale swarm trials at the Forge
Live military environment, supervised flight testing and controlled jamming — the same behaviour we measure in the lab, now proven in the field.
EDA Phase II Operational Experimentation
Continued path to EDA Phase II — worth up to EUR 750,000 — with national armed forces as end-users: TRL step-up on swarm autonomy, sensor-to-shooter integration and resilient multi-drone coordination.
Anti-Shahed interception
A Shahed-class drone becomes completely invisible in rain, fog or cloud cover — camera-based countermeasures fail, and legacy radar systems are too heavy, too expensive and too power-hungry for counter-drone deployment. Luftschar implements interceptor subsystems built around a miniature onboard radar: all-weather detection and interception at a fraction of the cost.
Autonomous drone interceptor for slower targets. The onboard miniature radar provides all-weather terminal guidance against Shahed-class cruise drones at low speed — no pilot required, fire-and-forget engagement in rain, fog or cloud cover.
Operator-controlled high-speed quadcopter drone for manual anti-Shahed interception. Fast reaction and a human in the kill chain when time-critical threats demand direct control.
Turbojet-powered fixed wing mirroring the threat's own airframe. Current idea: arm it with firearms to turn it into a multi-usage heavy drone platform.
Miniature onboard radar for the Shahed-interceptors. Optimized for close-range interception missions where weight and power efficiency matter most.
