Global navigational satellite systems provide accurate time synchronization and location services. Satellites transmit navigation messages that can be used by a receiver to compute its location. However, most navigation messages are not protected and are easily spoofed. Several attacks have been reported that transmit spoofed or replayed GPS signals to divert or hijack autonomous vehicles, ships and drones. Unfortunately, non-cryptographic protection methods that use antenna arrays, pseudorange differences and multi-receivers to detect GPS spoofing tend to be inaccurate due to environmental conditions.
