Multi-modem-based FHSS-drone takeover with precision spoofing

Abstract

Traditional radio frequency (RF)-based anti-drone technologies focus on jamming the command and control (C2) RF signal or global navigation satellite system (GNSS) signal of a target drone. Although these methods efficiently neutralize target drones, they may generate unintended RF collisions with other equipment and cause the drone to crash. We introduce a method for hijacking a frequency hopping spread spectrum (FHSS)-based drone through C2 signal emission for takeover and a precision spoofing signal to invalidate the owner's transmitter signal using a multi-modem in this work. The proposed method simultaneously transmits C2 signals to the target drone for safe takeover and precision spoofing signals to neutralize the owner's transmitter, thereby minimizing RF collisions with other equipment.
