Ground-truth magnetic sensing for the airport environment
A physical measurement layer that can't be jammed, spoofed, or denied — passive, continuous, GPS-timestamped. An independent integrity layer that complements RF systems, not a replacement.
Navaid EM integrity
Continuous magnetic baseline around ILS critical areas — detect environmental change (new ferrous structures, vehicle intrusions, construction) between flight inspections, with a GPS-timestamped evidence record.
Characterizes the magnetic/EM environment around critical areas — not a monitor of the ILS signal itself. Trace is the 60 s smoothed deviation product (raw 2.7 nT @ 1 Hz noise averages to ~0.35 nT).
Hold-line incursion detection
Passive ferrous-signature detection at the hold line — surface-mounted or below grade, like in-pavement vehicle sensors. No transponder required; it sees what's physically there.
Detection layer is ours to prove; the certified alert chain is the partner's. Architecture sized for sub-second detection-to-alert.
Energy & GIC resilience
Geomagnetic disturbance (GIC) monitoring for airport power systems, microgrids, and vertiport charging — the same physical field, watched continuously for the dB/dt that stresses ground infrastructure.
dB/dt evaluated on a 1-minute cadence — the basis for NERC/NOAA-style GIC thresholds (tens to hundreds of nT/min during storms).
Predictive maintenance
Every asset has a magnetic fingerprint; degradation shows up as drift before a conventional alarm trips. A fixed station tests live data against the healthy envelope — condition-based, not calendar-based.
Scope: fixed ground infrastructure — not airframe MRO. The maintenance trigger stays in your certified systems.
