Jamming rule

Aircraft counts as jammed when it reports NACp ≤ 2 (position error > 0.5 NM) or flags lost GPS, and stays that way for at least

Shorter drop-outs are mostly avionics glitches. Literature uses 60 s with 1 Hz data; our feed updates every ~20 s, so 2 min (≈ 6 samples) is the default. Aircraft that never reported a good fix are ignored.

Jammer position

Only outside allied territory

High-power jammers that reach aircraft hundreds of km away are expected in Russia, Belarus or at sea, so the estimate is searched only there. Turn off to search everywhere.
