GPS Spoofing Near Conflict Zones Blinds Civilian and Military Radar Systems

Radar systems increasingly depend on GPS for precise timing synchronization, geo-referencing of detections, and coherent integration of signals across distributed apertures. GPS spoofing — broadcasting counterfeit GPS signals to deceive receivers — has escalated from a theoretical threat to a daily operational reality. Since 2018, widespread GPS spoofing has been documented across the Eastern Mediterranean, Black Sea, Baltic Sea, and the Middle East, with aircraft ADS-B transponders reporting positions hundreds of miles from their actual locations. This affects not just navigation but the radar systems that fuse GPS-dependent data. The operational impact is severe. Air traffic control radars use GPS time stamps to correlate primary radar returns with secondary surveillance radar (Mode S/ADS-B) transponder replies. When GPS is spoofed, the correlation breaks — an aircraft's radar blip and its transponder-reported position diverge, creating false tracks, ghost targets, and dropped tracks. During the 2024 GPS spoofing campaign affecting flights over Iraq, Jordan, and the Eastern Mediterranean, multiple commercial flights received terrain proximity warnings in cruise flight because their GPS-derived altitude was spoofed to ground level. Eurocontrol documented over 50,000 GPS interference events affecting commercial aviation in 2023 alone. The problem persists for two reasons. First, GPS was designed in the 1970s without authentication — the civilian L1 signal is unencrypted and trivially spoofable with $300 in hardware. The military's encrypted M-code signal is resistant to spoofing, but civilian radar systems, ATC infrastructure, and allied military forces often lack M-code receivers. Second, there is no international legal framework that criminalizes GPS spoofing in international airspace or waters. Russia conducts GPS spoofing routinely to protect VIP movements and military installations, and there is no enforcement mechanism to stop it.
