Synthetic demonstration, not a real event
Every measurement below is invented. This record is published only to show the format of a PNTMAP™ event record while the live log is empty. It never appears in the live event log, the API, alerts, published statistics or share previews.
PNT-EVT-DEMO
Jamming-consistent ADS-B anomaly
A persistent, spatially bounded integrity degradation whose shape is consistent with a ground-based emitter. No direct RF measurement available, so jamming is not asserted.

What this means
Over roughly 96 minutes, a sustained majority of aircraft crossing one 0.5° cell reported a degraded navigation integrity category well above that cell's own 7-day baseline, while adjacent cells stayed nominal. That shape is consistent with a ground-based emitter, but no GNSS-band RF measurement was available, so jamming is not asserted.
Coverage limitations
The record describes only airspace inside the reception range of the listed nodes, during the stated period. Absence of a record elsewhere is not evidence of nominal conditions. Cause is not asserted. "Confirmed spoofing" is reserved for controlled tests, waveform-level evidence, or incidents independently verified by a third party. No automated PNTMAP™ classification reaches this rung.
