How to read these figures

The region is divided into hexagonal areas of about 1,770 km². For every hour, the monitor checks which share of the aircraft in each area reported degraded GNSS integrity (NIC) via ADS-B. An area-hour counts as affected when that share exceeds the threshold and enough aircraft were present. Spoofing indications are impossible position jumps and large GNSS/barometric altitude differences. These are heuristic indicators — see how the map works for details and limitations.
