Collects GPS interference data from GPSJam.org, which aggregates ADS-B Navigation Accuracy Category (NACp) values to detect GPS jamming and spoofing across geographic zones.
Schedule
Every 72 hours via Dagu (matches upstream update cadence).
Data source
GPSJam.org — GPS interference heatmap derived from ADS-B NACp degradation.
Processing
Fetch interference data for Baltic zones (Estonia, Latvia, Lithuania, Kaliningrad, Finland-S, etc.)
For each zone: count total aircraft reporting, count degraded aircraft (NACp below threshold)
Compute interference rate (percentage degraded)
Assign severity: HIGH (>10%), MEDIUM (5–10%), LOW (<5%)
