  "description": "During the Folkemødet political event on June 13, 2023, Bornholm and parts of the Baltic Sea experienced intense GPS jamming, disrupting GPS signals over land and sea. Experts from DTU Space noted that the scale and proximity of the jamming were greater than the previous year, with signals being jammed at ground level on Bornholm and Sweden, suggesting sources closer than Russia's Kaliningrad enclave. The GPS interference posed risks to critical infrastructure such as mobile networks, navigation, and financial transactions dependent on satellite time synchronization. Analysts suspect state-level actors due to the sophistication and extent of the jamming activity, likely involving multiple jamming devices possibly located on ships in the Baltic Sea near Bornholm.",

  "summary_extended": "In mid-June 2023, coinciding with the annual Folkemødet event on Bornholm, significant GPS jamming incidents were detected over the island and surrounding Baltic Sea areas. According to Søren Reime Larsen of DTU Space, this jamming was more potent and closer to the ground than prior incidents, which were previously traced to Russian Kaliningrad-based sources. The detection of jamming signal interference at ground level on Bornholm and nearby Sweden indicates involvement of jamming devices much closer, possibly on ships north of Bornholm. The GPS disruption threatens critical systems including mobile communications, financial transactions, and navigation, all reliant on precise satellite timing. Given the scale and technical sophistication, experts consider state-level actors responsible, raising concerns about security around Danish critical infrastructure during significant political gatherings like Folkemødet.",
  "summary_short": "Bornholm faced intense GPS jamming during the June 2023 Folkemødet, likely caused by state actors operating near the island.",
