BackgroundCross TeChnology evaluaTion PlugTesTs CoexisTenCe inTeroPerabiliTy of ETSI ITS-G5 and DSRC, 4 July 2011 17

– Critical infrastructures relying on GNSS-based services (i e timing and synchronization) are vulnerable(i.e., timing and synchronization) are vulnerable

– Country-wide fixed and wireless networks (i.e., internet), the power grid, banking services, stock markets, and sea, air, rail and road transportation networks,…

– IPSC is currently investigating the vulnerabilities of GNSS systems to:y– anthropogenic interference sources (e.g., DBV-T, RFI, …)– natural interference sources (e.g., space weather)

Common Main RecommendationsCross TeChnology evaluaTion PlugTesTs CoexisTenCe inTeroPerabiliTy of ETSI ITS-G5 and DSRC, 4 July 2011 19

– GNSS should be classified as a Critical Infrastructure (6-8% of GDP!)

– A GNSS Interference Geolocating and Reporting System shall be

deployedp y

– Shutting down and prosecution of interferers

H d i f GNSS i d t– Hardening of GNSS receivers and antennas

– Establish GNSS backup systems to guarantee PNT operations (e.g,

aviation)
