Since its creation, the Global Positioning System (GPS) has grown from a limited purpose positioning system to a ubiquitous trusted source for positioning, navigation, and timing data. To date, researchers have essentially taken a signal processing approach to GPS security and shown that GPS is vulnerable to jamming and spoofing. In this paper, the authors systematically map out a larger attack surface by viewing GPS as a computer system. Their surface includes higher level GPS protocol messages than previous work, as well as the GPS OS and downstream dependent systems. They develop a new hardware platform for GPS attacks, and develop novel attacks against GPS infrastructure.
