Baltic & Eastern Europe GNSS Jamming/Spoofing: Aviation & Maritime Impacts

by | Jul 22, 2025 | Geosec, Security

What happened. Summer 2025 reports show sustained GNSS interference across the Baltic region—researchers identify ship-borne or Kaliningrad-linked jammers; GPS World and Defense News detail the operational impact. EASA/IATA announced a joint plan to mitigate GNSS interference, and the EU’s Galileo OSNMA moved to operational status to authenticate signals.


Why it matters. Spoofing/jamming can degrade RNP/RNAV procedures, push aircraft to ground-based backups, and confuse maritime ECDIS/ETA planning—raising safety and cost.


BladeOne’s POV — do this now.

  • Implement multi-sensor nav (IRS + DME/DME + VOR) fallbacks and RAIM/RAIM-like alerting; brief crews on spoofing SOPs.
  • Monitor NOTAMs + NAVCEN and regional ops feeds; add spoofing/jamming flags to dispatch tooling.
  • For fleets, deploy anti-spoof receivers (Galileo OSNMA-ready where possible) and train for loss-of-GNSS scenarios.
