Nobody can see past the wall.
A fire captain tracks an interior crew by radio roll call. An entry team goes through a door knowing only what it saw from outside. Both are guessing, and the guess is what kills people.
GPS dies indoors
Accountability for who is on which floor falls back to voice, memory, and a status board.
Optical dies in smoke
Cameras, LiDAR, and the eye all quit in a working fire. Thermal sees further but stops at the first solid surface.
Prediction is not detection
Tracking a target from outside the building predicts where it went. If someone is already inside and still, that prediction is worth nothing.
Now somebody can.
WARDEN is one package: radar, UWB and imaging fused into a single position estimate. Radar and UWB each run on the bench today, and fusing them is the current work, so everything below is the finished system rather than what ships now.
Zero-setup positioning
Nothing surveyed, nothing wired. Nodes are placed on arrival and work out their own geometry, inside the window a crew actually has.
UWB self-geometry · no surveyed infrastructureTagged and untagged tracking
Every tagged crew member tracked through walls, plus untagged people carrying nothing at all, including anyone lying still.
Radar and UWB fusionMulti-sensor confirmation
A detection has to be seen by more than one physics before it reaches the commander.
Rule-based arbitrationLive interior picture
Positions rendered against structure geometry rather than a blank grid, so a commander reads rooms instead of dots.
LiDAR-SLAM mapping · open streaming APIWhere the physics stops us
Penetration trades directly against resolution. The high-band sensing that resolves a person cleanly through drywall does not meaningfully pass through brick or reinforced concrete. Physics sets that limit, not our software. The finished package pairs both bands rather than betting on one.
Everyone else picked a half.
The tools in this space are mature and they work. Each one solves half the problem, and the halves do not compose: two vendors, two devices, two coordinate frames.

What a competitor cannot buy
Every module in this stack is something a competitor can buy, and several of them build excellent products from it. What nobody sells is one frame: tagged crew and untagged occupants in a single picture, from a system already in place before anyone reaches the door. The arbitration behind that is the hard problem, and it is the only part that compounds, because deployments sharpen it program by program.
From bench to burning building.
Proof of concept
One position estimate from radar and UWB together, proven end to end on a ground prototype.
Full sensor package, field-ready
The bench system becomes a deployable one. The remaining modalities join the RF core, and the whole package fits a handheld unit with no laptop in the field.
Body-worn sensing
A radar carried on the operator, pointed wherever they look, fused as another moving node. The sensor's own motion becomes a ghost-suppression advantage, which de-risks the airborne work directly. Deployments produce the labelled data a trained classifier needs, held within its own program.
Airborne, GPS-denied
Drones positioned around a floor, sensors looking inward, ranging against each other so drift never accumulates. Triangulation from opposing corners, streamed to a ground station.
Two buyers, one box.
One problem, two buyers, two programs that never touch. They share the engineering and nothing else: separate deployments, separate data, separate delivery. The commercial side hardens the hardware without the government side ever depending on it.
Fire & EMS
Agencies already run Drone as First Responder (DFR) programs. Those aircraft arrive first and see only the outside. WARDEN supplies the inside.
- Live position of every interior crew member, no GPS
- Unlocated occupant detection through walls
- Throw-and-walk deployment
Defense & Intelligence
Room clearing and subterranean operations need the same measurement: who is behind this wall, right now.
- Pre-entry interior picture for close-quarters operations
- GPS-denied and subterranean positioning
- ITAR-walled program, separate data and delivery
Emergency payload delivery
The aircraft that carries our sensors can carry equipment. An AED or blood products reach a patient ahead of the ambulance, flown by the agency already operating the package. The flying is proven; the gate is BVLOS authorization.
Payload delivery only. We are not pursuing patient transport.
How we sell into both
We are not building the command platform. WARDEN is software-agnostic hardware with an open streaming API, publishing into the systems our customers already run: TAK on the public safety side, Lattice-class on defense. We supply the measurement and the incumbent owns the screen.
