Interference, as it happens — and as it happened.

What we watch
  • LEOSpace-based RF interference and GNSS reflectometry
  • ADS-BAircraft position anomalies
  • AISVessel position anomalies and dark ships
  • CORSReference-station jamming and spoofing

Findings indicate anomalies. They are not confirmation of jamming or spoofing — the same signatures can arise from multipath, equipment faults, or ordinary signal conditions.
