Physical intelligence, joined honestly

One operating picture
for the physical world.

Arden turns home sensors, radio instruments, and Earth observation into one operating picture—without flattening uncertainty or inventing precision.

ONEWORLD MODELEVIDENCE ATTACHED
Home SenseRF LabOpenSARSignal Library

Rooms, presence, devices, coverage, and sensor health stay private by architecture. Boundary: Joins the world model without pretending every home observation is coherent k-space.

Spectrum, emitters, FMCW, apertures, Doppler, and instrument state. Boundary: Phase adds only inside a declared reference; passive views remain explicitly RX-only.

Orbital apertures sample the same physical scene at planetary scale. Boundary: A single collect resolves the support it measured and refuses the missing axis.

Signatures, fixtures, fingerprints, limits, falsifiers, and external references. Boundary: Reference records never impersonate Arden measurements or portable device identity.

Space Radar

Explore how signals of opportunity, orbital geometry, and a two-channel receiver could become a passive space observatory—with the unmeasured links kept visible.

Jammer Findings

Detect and characterize a denial event, preserve its schedule and spatial signature, then stop where the evidence stops. The public record establishes an event family—not a portable transmitter identity or a position.

The honesty layer

Every claim travels with its limits.

Select an evidence chain. The same display standard follows a result from source to operator to claim—and makes the stopping boundary as visible as the result.

The Arden contract

Every position carries uncertainty. Every identity carries provenance. Every instrument can say not established.
