Improving GNSS Spoofing Awareness in Smartphones via Statistical Processing of Raw Measurements by Akmal Rustamov, Alex Minetto, Fabio Dovis

“…Vulnerability analysis and validation of the proposed technique were conducted in a controlled environment by transmitting realistic, counterfeit Global Positioning System L1/CA navigation signals to a variety of Android smartphones embedding also different GNSS chipsets. We show that, under proper conditions, the devices were vulnerable to the attacks and that the effects were visible through their raw measurements, i.e., Carrier-to-noise ratio <inline-formula> <tex-math notation="LaTeX">$(C/N_{0})$ </tex-math></inline-formula>, pseudo-range measurements, and position estimates. …”
