  "description": "A detailed analysis of large-scale GNSS jamming (Electronic Warfare) activity affecting the Baltic Sea region during the NATO exercise Operation Steadfast Defender on April 4, 2024. This electronic warfare action caused severe GPS disruptions impacting civilian and military aircraft, as visualized through open-source interference heatmaps and aviation data. The jamming originated from locations in Russia, Belarus, and Kaliningrad, affecting Baltic states, southern Finland, and northern Poland.",

  "evidence": [
    "Screenshots from GPSJAM.org showing widespread GPS jamming heatmaps on April 4th, with intense interference emanating from Kaliningrad, Russia, and Belarus.",
    "Quoted analysis from @auonsson detailing disruptions for both civilian and military flights.",
    "Flight tracking data and NOTAM bulletins referenced as corroborating signals interference in aviation."
  ],
  "evidence_quotes": [
    "The 2024-04-04 GNSS jamming in the Baltics was on a unprecedented scale.",
    "The most probable cause for this is the ongoing NATO exercise Steadfast Defender, which has also been noted in several aviation information bulletins.",
    "Sources of GNSS jamming are from Kaliningrad, western Russia and Belarus.",
    "The impact covers the air corridors over the Baltic States, Southern Finland and Northern Poland.",
    "A clear pattern of jamming intensity can be seen on the map with red indicating heavy interference."
