May 2021: German broadcasting station Südwestrundfunk (SWR) featured Dr. Humphreys in their news report on GNSS spoofing. In his interview, Dr. Humphreys explains the leading theory on GNSS spoofing in Syria: that the Russian military has been deploying "bubble of GPS spoofing" to help protect Vladimir Putin on his visits there. Watch the news broadcast on YouTube here.

This report, entitled "Above Us Only Stars," is an in-depth review of the Russian spoofing activity. The RNL was a major contributor to this report. 

RNL member Matthew Murrian's paper "GNSS Interference Monitoring from Low Earth Orbit" describes how the RNL detected spoofing activity in Syria via a receiver on the International Space Station.
