3 Presentation Contents Background What, Who and Why? Latest SENTINEL Jamming Detections Vulnerable Applications Conclusions
4 Background GPS Interference & Jamming Royal Academy of Engineering Report Published Space Weather Royal Academy of Engineering Report To be published Feb 2013
5 Interesting Headlines! Feb 2012 GPS jamming: a clear and present reality A secret network of 20 roadside listening stations across the UK has confirmed that criminals are attempting to jam GPS signals on a regular basis. May 2012 GPS Vulnerable To Hacks, Jamming This week, the South Korean government reported that electronic jamming signals from North Korea were affecting communications and GPS signals for passenger aircraft..
6 The SENTINEL Project GNSS SErvices Needing Trust In Navigation, Electronics, Location & timing 2011: UK Government Funded R&D Project, 2 years, ~ 1.5m through Technology Strategy Board Trusted Services Call Research to establish extent to which GNSS and eloran PNT signals can be trusted 11/05/2015 6
7 11/05/2015 The SENTINEL Partners ACPO-ITS Association of Chief Police Officers User Community Law Enforcement Brings other Government agencies into the collaboration GLA General Lighthouse Authorities User Community - Maritime eloran University of Bath - Dept. of Electrical & Electronics GPS & Space Weather Ordnance Survey User Community Land Geolocation NPL National Physical Laboratory Time, UTC Traceability Thatcham Vehicle Security Certification of safety critical services Chronos Technology Ltd GAARDIAN Research SENTINEL Project Leader 7
8 SENTINEL Research Can we detect? Can we prove it s a jammer? Can we locate, identify, seize? Can we determine extent of problem? Can we create actionable intelligence? Can we show that eloran is a viable complement to GNSS for PNT?

10 Presentation Contents Background What, Who and Why? Latest SENTINEL Jamming Detections Vulnerable Applications Conclusions
11 What, Who and Why? Interference to GNSS Unintentional Jamming, e.g. RFI at L1 Serious Multipath Space Weather Poor Workmanship GNSS Jamming Deliberate jamming Unintentional consequence of jammer use Spoofing & Meaconing
12 Example of RFI 15 Storey Building in London 17 Minute Loss of GPS!
13 Example of Serious Multipath Gantry over highway Adjacent to big reflectors 15 Minute compromise
14 Space Weather 11 Year Solar Cycles Aurora Borealis Carrington Event 1859 Solar Flares (8 Minutes) Coronal Mass Ejection CME Up to 2 days Nasa Univ of Bath

16 Poor Workmanship This is what you get if you ask 17 th Edition Electricians to install your GPS Antenna!
17 Presentation Contents Background What, Who and Why? Latest SENTINEL Jamming Detections Vulnerable Applications Conclusions
18 Who does Jamming? Civil, Criminal, Terrorist and State Evasion of GPS tracked car insurance Evasion of Company Vehicle Tracking Systems Evasion of Road User Charging Schemes & tachographs Stealing High Value Assets, Cars, Vans, Loads Evasion of Covert Tracking Securing Off-Site Meetings Evasion of Criminal Tagging Intentional attack by foreign power or non-state
19 GPS Tracked Car Insurance Pay as you drive insurance Young driver insurance Fleet insurance Black box insurance Telematics insurance
