SENTINEL Report on Emerging Threat From Low-Cost Jammers
Chronos Technology SENTINEL project was supported by the United Kingdom Technology Strategy Board (TSB).
“Its roots lie in an earlier TSB-supported project, GAARDIAN. SENTINEL set out to examine various aspects of the emerging threat from low-cost commercially-available GPS jammers.
The project has found that the problem is clearly getting worse with some locations detecting 5 to 10 events per day; over 50 web sites selling jammers and law enforcement seizing much more powerful jammers with much greater ranges and coverage. Whereas GPS was the only satellite PNT system under threat in 2008, now it is all the GNSS frequencies including Galileo.
One important conclusion has become evident from the work on GAARDIAN and SENTINEL over the past 6 years: the GPS jamming threat is getting worse; most people don’t yet ‘get it’; and a ‘Black Swan’ event will happen in the UK, just as has already occurred in South Korea.”
