See the magnetic field.Find what others can't.
A portable, passive sensing platform that monitors the magnetic field, fingerprints interference, and locates and tracks buried or moving sources — a quiet complement to RF and counter-UAS airspace defense. The demos below run live in your browser — nothing to install or configure. In production the same software reads from deployed NextMAG sensor hardware.
Spectral Monitor
Live magnetic field with a real FFT spectrum and scrolling spectrogram — 50/60 Hz harmonic & EMI fingerprinting.
Open live demo →Source Locator
Invert a line of surface sensors to pinpoint a buried source's position and estimate its depth, with confidence.
Open live demo →Magnetic Camera
Reconstruct the field over an area and localize a source in x, y, and depth — point-sensors become an imager.
Open live demo →Live Tracking
A daisy-chained mesh tracks a moving source in real time, with live and rolling error and confidence.
Open live demo →Predictive Maintenance
Learn a machine's healthy signature, then catch bearing-fault drift early with a trend-based health score.
Open live demo →Live Space Weather
High-cadence NOAA SWPC feed — Kp/G-scale, solar wind, IMF Bz, and live GOES X-ray flare class.
Open live demo →Vehicle Gate (2 units)
Two live units spaced along a road log every passing vehicle with direction, speed, and size — the airport chokepoint on a real street.
Open live demo →Airport Ground Safety
A hold-line monitor for runway incursions — passive vehicle detection at the chokepoint — plus GIC space-weather awareness for the airfield.
Open live demo →Have a NextMAG station?
Stations report to the platform over their gateway when they are networked, so those readings appear here from anywhere. Standing next to a unit, this app can instead join the unit's own WiFi and read it directly — that is what the connect screen does.
