Prof Curry was awarded the Fellowship in recognition of his significant and continuing contribution to the practical aspects of time measurement and dissemination, including research into GNSS vulnerabilities and the use of eLoran for precise time.
This research has been undertaken within two Innovate UK (the UK Government Innovation Agency) research projects GAARDIAN and SENTINEL. GAARDIAN (GNSS Availability Accuracy Reliability anD Integrity Assessment for timing and Navigation) focussed on detecting GPS jamming and monitoring eLoran signals on a 24x7 basis for precision resilient timing applications. SENTINEL (GNSS SErvices Needing Trust In Navigation, Electronics, Location & timing) followed on and researched ways to geolocate jammers and resulted in the first UK seizure of a jammer. This was an exercise by Law Enforcement Officers that took just a couple of weeks once a pattern of use had been determined. SENTINEL also showed that eLoran signals are as accurate as GPS signals for UTC time dissemination, work in doors, and are not susceptible to the same jamming and interference as GPS or other future GNSS signals such as Galileo.
