'We were able to uncover evidence that systems used to spoof GNSS signals are also being deployed on the ground in Syria,' the report says. C4ADS says it found GPS spoofing on both occasions that Putin visited the area. The construction of the bridge, between Ukraine and Russia, has been condemned by Nato, while Russian naval operations have also taken place in the area.
On both May 15 and September 15 last year, Putin visited the area around the Kerch Bridge (also known as the Crimean Bridge). 'In almost all cases where brief GNSS spoofing events occurred in remote locations in Russia and Crimea, such as in Arkhangelsk, Vladivostok, and Kerch, we found that spoofing events directly coincided with visits by Russian president Vladimir Putin,' the report says.
Spoofing has been found in ten locations in Russia: Gelendzhik, Sochi, Vladivostock, Saint Petersburg, Olyva, Arkhangelsk, Kerch, Moscow, Sevastopol, Khmeimim.īy monitoring the publicly disclosed location of Putin the researchers were able to say that GPS signals were seemingly spoofed to obfuscate his movements. The group's report is based on publicly available data from the AIS shipping system, satellite images, information from the ISS and previous reporting of GPS problems.
