    "Over the past year, there has been a marked increase in disruptions to satellite navigation systems across the Gulf of Finland, with reports of aircraft and ships receiving false GPS signals.",
    "Evidence points to GNSS spoofing activity originating from the Russian side of the border, raising questions about its purpose and impact.",
    "Evidence of GNSS spoofing in the area is clearly visible on ship-tracking sites such as MarineTraffic.com and VesselFinder.com. Vessels appear to follow standard shipping routes, only to suddenly ’teleport’ to a new location and begin moving in circular patterns.",
    "The circle-spoofer ... reveals a perfect circle with a radius of 8.6 km centered on N 60° 25’ 27 E 27° 52’ 48.",
    "The spoofed target locations can be freely set by the operator, meaning the spoofed position does not indicate the actual location of the spoofer. In this case, the false positions appear to be in areas with no obvious military significance."
