At present, the control signals used by drones are mostly in the general civilian frequency bands such as 1.2GHz, 2.4GHz, and 5.8GHz. With the rapid development of open source hardware such as Arduino and Raspberry Pi and the popularity of software-defined radio (SDR) technology, ordinary fans You can also use the hardware purchased from the Internet and the software source code obtained from the forum to simulate the remote control to send control signals to the drone, and cover the signal of the real remote control to obtain the control power of the drone. The drone jammers is A signal jamming device for scrambling uav signal.
Many drones use Wi-Fi to interact directly with mobile devices such as mobile phones and tablets. In this way, some hacking techniques already mature in the Internet can be directly applied to drones, such as drone candid photos, drones stealing secrets, drones affecting flights, etc. This can be avoided by using a uav scrambler.
