According to an Iranian engineer quoted in the article, "By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain." Apparently, once it loses its brain, the bird relies on GPS signals to get home. By spoofing GPS, Iranian Engineers were able to get the drone to "land on its own where we wanted it to, without having to crack the remote-control signals and communications."
