  "description": "Significant surge in GPS jamming activity and PNT (Positioning, Navigation, Timing) disruption recorded over southern Sweden and the Baltic Sea region on April 29-30, 2024. Maps visualized increased GNSS interference spreading from Kaliningrad, impacting airspace and navigation over Sweden and the Baltic states. Flight and ship operations may have been affected. The data is supported by multiple graphics and visualizations correlating aviation and maritime implications. The origin of disruption appears to be linked to Russian operations from Kaliningrad enclave.",
