Sovereign sensing · Low-altitude airspace

We detect, track and hold drones
OVER THE SITES THAT MATTER.

A scalable, EU‑sovereign sensing mesh: distributed millimetre-wave (mmWave) radar plus agentic command and control (C2), protecting ports, airports, energy and defence. What follows is a simulated incursion scenario, end to end. Illustrative animation; not field data.

§01 · The Gap

mmWave at 77 GHz owns the cluttered low-altitude volume, from ground to several hundred metres above ground level (AGL), where exquisite radar is uneconomic and legacy aviation radar is unsuited to the clutter regime.

§02 · The System
Subsys / 01 · Sensing Mesh

Radar tiles, orchestrated

Off-the-shelf radars in an ÆTHERION mesh. Add nodes to scale coverage. Occlusion-free coverage comes from geometry: another node holds the target from a different vantage. The radars are commodity; the mesh, orchestration and software are ÆTHERION's.

Subsys / 02 · Vigil · Agentic C2

Vigil

Multi-tile fused tracking from the mesh, geofence intent gating, full audit and replay. Pattern-of-Life baselines and the agent layer, human-on-the-loop classification with human-in-the-loop action authorisation, are the Mark III design direction.

§03 · Occlusion-Free Hold

The target passes behind the terminal. One node loses line of sight; the geometry holds the track.

§04 · Configuration Dossier ÆTHERION Space & Defence

One mesh. Two configurations.

CFG / A · Full Stack

Mesh + Vigil

For civilian critical infrastructure: the sensing mesh with Vigil as the command-and-control layer, operated by the site.

CFG / B · Sensor-Only

Mesh into your mission core

For primes and integrators whose mission core owns the C2: the mesh delivers tracks and events into your layer. Open, documented interfaces at the track and event level. The mesh, orchestration and software layer are built and held in the EU.

§05 · Node lost · Designed to hold

The wedge is coverage completeness, not a cost multiple: tiled low-cost nodes cover the full air volume of a site's protected airspace, occlusion-free, where a single legacy radar, cheaper per square kilometre, leaves occlusion gaps behind every structure.

Built for attritable use. A damaged or destroyed sensor node is replaceable as consumable infrastructure. The cost basis matches the threat environment, high-attrition mass-drone, instead of pricing in the assumption that the threat hasn't changed.

Four decades of radar. Two founders who write the software.

P / 01

Sebastian Asprella

Founder & Chief Executive

Builds and owns ÆTHERION's command layer: Vigil, the agentic C2 above the radar platform, with operator console, agent layer, audit and replay; and Loom, the publishing layer that carries tracks into it. Two-time founder; previously led ThinkOrbital to the first autonomous welding in space, with more than $11M in NASA, US DoD and US Space Force awards, cash and in-kind, alongside SpaceX, Blue Origin and Northrop Grumman. Fourteen enterprise systems delivered end to end at a European regulator, from business case to adoption, across a portfolio of 120+ contractors.

Shakil Perera

COO · Operations & Execution

Imperial College aeronautical engineer. Co-founded the Karman Space Programme, leading 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.

Phil Briot

CTO · Platform & Signal Chain

Engineer from Thales Electronic Warfare, one of Europe's three primes. Owns the platform architecture: RF and signal chain, node integration, SDK, interface contracts, and the security and signed-update baseline.

P / 04

Tom, PhD

Chief Scientist · Signal Processing & Evidence

Signal-processing PhD. Approximately €1M in competitive radar research funding secured as PI across mmWave and radar programmes. Owns the science behind ÆTHERION's claims: KPI definitions, measurement methodology, and the test protocols that translate radar performance into procurement-readable language.
