- The page says readings come from aircraft GPS accuracy over the prior 24 hours; empty areas may reflect sparse flights or volunteer coverage.
Field notes
The page says readings are derived from GPS accuracy reported by aircraft in flight during the previous 24 hours and groups affected readings into three percentage bands. Its coverage depends on volunteer receivers and civil flights, so it explicitly cautions that blank areas do not establish that interference is absent. The page lists conflict jamming, illegal jammers, space weather, authorized tests, and aircraft equipment among possible causes.
