Most RF Jammers include the band to target GPS/GNSS frequencies. Many drones now have a satellite link such as GPS/GLONASS/BeiDou, which is used for drone navigation. Many drones use GPS to fly autonomously with autopilot mission planner. This type of Jammer will work and jam the GPS satellite signal. The Fail Safe mode starts to work and force the drone to land or return to home. Now airports do not allow GPS Jammer to be deployed due to interfered frequency for GPS communications.
