The sovereign sensing layer for Europe's low‑altitude regime.
Distributed mmWave radar mesh and agentic command and control for NATO Europe's defence sites and critical infrastructure. SAPIENT-native by design. EU-sovereign supply chain end to end.
Outdoor radar campaign. Real hardware. Real conditions. See the evidence posture →
See the drone, not the radio signal.
The drones penetrating sensitive European sites today do not emit. Fibre-optic FPV, autonomous terminal guidance, GNSS-denied flight. Air defence built for the previous decade assumes the threat keeps talking. It doesn't.
Listen for the radio signal.
Today's air defence detects RF emissions from the drone: command links, control telemetry, GPS feedback. The drone has to talk to its operator for any of this to work.
Fibre-optic and autonomous FPV.
Fibre-spool and autonomous first-person-view drones penetrate sensitive sites at close quarters. No radio signal to detect. Mass combat use in Ukraine on both sides since 2024.
See the physical object.
Distributed millimetre-wave radar mesh built on mass-produced automotive silicon. Independent of whatever the drone does or does not emit. Complementary to long-range radar, not competing with it.
Long-range S/X band radar owns outer perimeters and high altitude. mmWave at 77/78 GHz owns the cluttered low-altitude volume, from ground to several hundred metres AGL, where exquisite radar is uneconomic and legacy aviation radar is unsuited to the clutter regime.
Sensor mesh, plus the trust layer on top of it.
ÆTHERION ships the sensor subsystem and the operator console as one integrated stack. Operator workflow, agent layer, and audit trail are the trust layer — not commodity software.
Distributed mmWave tiles.
Cooperative network of 77/78 GHz radar tiles. NLOS-capable through clutter. Micro-Doppler classification. Multi-tile fusion. EU-sovereign supply chain end to end.
Agentic operator console.
Multi-tile fused tracking, Pattern-of-Life baselines, ROE-aware geofencing, agent layer with human-on-the-loop classification and human-in-the-loop engagement authorisation, tamper-evident audit and replay. The trust layer.
SAPIENT-native cue stream.
SAPIENT (BSI Flex 335) is the open NATO C-UAS sensor-to-command standard. Tested at NATO TIE21 and TIE23, credited by Dstl as supporting live operational protection at the NATO Summit in The Hague (2025). ÆTHERION is SAPIENT-native by design.

Inside the standard. Two ways to deploy.
ÆTHERION is built to slot into the NATO and EU sensor-to-command ecosystem on the existing standards — not adjacent to them. Two integration patterns; same hardware mesh.
BSI Flex 335. The open NATO C-UAS sensor-to-command standard. Native serialisation, no translation layer.
The Technical Interoperability Exercise series. Where C-UAS sensors and command stacks are tested against each other on the standard.
Defence Innovation Accelerator for the North Atlantic. ÆTHERION's capability profile maps to DIANA challenge briefs.
Silicon to software. EU-sovereign supply chain. EDF-eligible. Built in Luxembourg under EU jurisdiction.
Sensor mesh + Vigil.
Sites with no upstream mission core: ports, airports, energy, data centres, government buildings. ÆTHERION delivers the full sensor-to-decision stack, with Vigil as the operator console.
Sensor mesh under prime C2.
Defence customers operating under a prime's mission core: the sensor subsystem cues into the existing C2 over SAPIENT. ÆTHERION ships the mesh, the prime's mission system makes the decisions.
Two configurations on the same hardware mesh: full stack with Vigil for civilian critical infrastructure; sensor-only when a prime's mission core owns the C2. Customer-matched at deployment. The integration boundary is the SAPIENT cue stream, an open standard, not a proprietary interface.
What the system does. How to verify it.
ÆTHERION publishes its capability posture as a capability inventory plus a buyer-readable evidence pack. No screenshots in place of measurements; no slideware in place of test protocols. Roadmap, milestone schedule, and the evidence pack itself are held in the dataroom.
Buyer-readable evidence, not marketing.
ÆTHERION's Evidence Pack documents KPI definitions, measurement methodology, instrumentation, test conditions, and result chains in language that survives procurement review. Available to qualified critical-infrastructure operators, prime integrators, and government buyers on request.
- KPI definitions traceable to standards
- Instrumentation and reference-target inventory
- Per-scenario test conditions and weather log
- Raw data chain to fused track output
- Independent reviewer notes where applicable
Commercial materials, by NDA.
Business model, unit economics, roadmap and milestone schedule, customer letters of intent, programme pipeline, capital structure and team detail beyond this site are held in a dataroom available to qualified investors and procurement parties under NDA. Route via the Chief Executive.
Domain depth where it matters.
Radar industrialisation, defence signal processing, regulated procurement, operations. Both halves of a defence company under one roof: engineering and procurement.
Founder of ÆTHERION. Owns Vigil — the agentic command-and-control layer above the radar platform. Two-time founder; previously led an aerospace company to the first autonomous welding demonstration in space. 25 years of international working experience across regulated environments.
Engineer from Thales Electronic Warfare. Owns ÆTHERION's platform architecture: signal chain, multi-tile fusion engine, SDK, interface contracts, schema definitions, and the security and signed-update baseline.
Imperial College aeronautical engineer. Co-founded the Karman Space Programme; led 50 students to multiple launches and a 3D-printed regenerative bi-propellant engine. Drives build, test, and delivery cadence from Mark II to pilot readiness.
Signal-processing PhD; principal investigator on mmWave and radar research programmes. Owns the science behind ÆTHERION's claims: KPI definitions, measurement methodology, evidence defensibility, and the test protocols that translate radar performance into procurement-readable language.
Senior operator across regulated industries. Bundeswehr naval officer background. Owns ÆTHERION's German vector (Hamburg Port Authority, Bundeswehr Innovation Centre, German Navy) and prime-integrator correspondence with Hensoldt, Rheinmetall, KNDS, MBDA, Leonardo and Saab.
