Very high interference: over 50% of aircraft, 12 or more of them
12 of 12 aircraft (100.0%) reported low position accuracy at least once in this cell.
A cell needs three aircraft to be drawn. Yellow and red need at least two affected aircraft and purple at least twelve, so one faulty receiver cannot colour a cell. Low accuracy is evidence of interference, not proof of jamming.

Too few aircraft crossed this cell below 5,000 ft or above 15,000 ft to compare the two: five are needed in each.
Each layer is coloured as on the map, except that below 5,000 ft red starts above 20% and yellow at 8%, because receivers near the ground lose accuracy more often for ordinary reasons, such as hills and buildings hiding satellites. How altitude is read
Possible causes
Possible causes include jamming, spoofing, military testing, equipment faults or space weather. The data alone cannot say which, or who is responsible.

Neutrality. We measure and describe data, it is not our job to take sides. The map records where aircraft lost position accuracy, which can come from jamming, spoofing, military testing, equipment faults or space weather. Our data alone can't say who is responsible, so we don't. When we mention a likely source, it's because a government, regulator or reputable outlet has said so publicly. That is their assessment, not ours, and we link to it. Region names and borders follow common international usage and imply no position on any dispute.
