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)
