Quantum sensing,
out of the lab.
NV-diamond magnetometers designed for the vehicle, not the lab — room temperature, chip-scale, sovereign.
The digital twin
Our sensor already flies — in software.
Before the first device is built, an end-to-end navigation digital twin flies the mission: a synthetic magnetic map, a vehicle with its own interference, the full sensor model and the navigation filter — every figure honestly labelled as model-derived.
It is how we engineer, and how we intend to be measured: the twin’s predictions are the targets our hardware milestones will be judged against. The interactive twin is online — access is granted on request.

The problem
When GPS goes dark, everything that depends on it drifts.
Satellite navigation is jammed, spoofed and denied across contested airspace, deep oceans and orbit. Inertial systems drift the moment the signal drops. The world needs a positioning reference that nobody can switch off — one that emits nothing and cannot be jammed.
Magnetic navigation exists — but the magnetometers flying today are lab instruments strapped onto vehicles, corrected by external compensation models dating back to 1953. We design the sensor for the vehicle, not the lab. They compensate. We measure.
How it works
From the Earth’s field
to a true heading.
Four stages, one chip-set — and the stage in the middle is the one nobody else does on board.
01
Sense
The NV-diamond reads the Earth's ambient magnetic field — a fixed, global signature that no one can switch off.
02
Reject
The vehicle carries its own magnetic noise — motors, currents, ferrous masses. Our sensing architecture identifies and removes it on board, in real time.
03
Match
Onboard firmware matches the cleaned reading against a magnetic map to resolve position and heading in real time.
04
Navigate
It continuously corrects inertial drift — holding a true course with no satellites, no emissions, nothing to jam.
The approach
A single quantum core. Engineered diamond.
A nitrogen-vacancy centre in diamond is an atom-scale magnetometer that works in ambient conditions. We turn that physics into a manufacturable sensor — diamond, integrated optics, and adaptive firmware — designed in software before it ever reaches the cleanroom.
Room temperature
No cryogenics, no shielded room. The sensor runs warm and field-ready, where SQUIDs and cold atoms cannot go.
Vibration-immune
Solid-state diamond holds coherence under shock and motion — built for vehicles, hulls and launch loads.
Passive & silent
It reads the ambient field and emits no RF. Nothing to detect, nothing to jam, nothing to spoof.
Vertical #1 — Navigation
One core. Three theatres.
Navigation ships first. The same sensing core corrects inertial drift across air, sea and space — wherever satellites fail to reach.
Air
Matchbox-sized, a handful of watts. Rides on tactical UAVs and holds heading by matching the Earth's magnetic map the moment GPS drops.
Sea
Fully passive underwater navigation and magnetic-anomaly detection for submarines and AUVs, where satellite signals never reach.
Space
Diamond is intrinsically radiation-hard — attitude and orbital navigation that keeps working under cosmic radiation.
The engine behind the sensor
SF-QSim — designed in software first.
Our sensors are simulated before they reach the cleanroom. SF-QSim is a first-principles physics engine that predicts coherence and magnetic sensitivity across independent decoherence channels — the design layer that lets a lean team move at deep-tech speed.

Experimental anchors behind the engine
European, sovereign deep tech.
We design the sensor, the firmware and the calibration — and we take quantum out of the lab. We’re courting partners and investors who want in early.
