Manipulating GPS Signals to Determine the Launch Location of Drones in Rescue Mode

The use of drones for civilian purposes has recently grown. Drones are used for recreational, commercial, and governmental purposes. Today's drones can fly over a long range and many of them are equipped with cameras and a GPS chip to allow users to control them over a long range. This creates privacy and security concerns. For example, drones flying in restricted areas, or using the camera to spy on individuals and entities This paper addresses this issue and proposes a method to respond to violating drones by exploiting the lack of source authentication in GPS systems. In this paper, we propose a technique to ground and find the launch location of violating drones. This is done by invoking the rescue mode, then, employing Radio frequency software-defined radios to broadcast manipulated GPS signals following a novel algorithm that not only grounds violating drones but also find the drone's launch location, which is what unique about our approach. In this paper, we present the proposed method. Then, we perform both hardware tests and a simulation to demonstrate the proposed system's performance.
