How often GNSS interference happens

Every figure counts incidents: groups of neighbouring map cells where several aircraft reported degraded satellite positions at the same time. An incident is counted on the UTC day it starts.

Detection depends on air traffic: fewer aircraft at night over some regions means fewer chances to observe interference.
