Main impact



Recommendations to Port to reduce GPS/AIS jamming/spoofing risks:

  • Implement verification mechanisms for GPS and AIS data.
  • Use multiple sources of location (other GNSS constellation, physical checks) to cross-verify GPS/AIS information.
  • Regularly monitor for signal interference and anomalies in navigation systems.
  • Use Controlled Radiation Pattern Antennas.
  • Educate personnel about the risks and signs of GPS/AIS spoofing attacks.
  • Work with your CSIRT organization to know the geographical zones at risk.
