Researchers have developed a tool that poses as GPS satellites to deceive nearby GPS receivers and manipulate road navigation systems. The kit could be used to deceive receivers used by navigation systems and suggest drivers the wrong direction. The group of researchers is composed of three teams from Microsoft, Virginia Tech in the US, and the University of Electronic Science and Technology of China. The tests conducted by experts allowed to remotely change the routes with up to 95 per cent accuracy. The researchers built a radio-transmitting device based on Raspberry Pi, they used just $223 of components.”]
