How can drone jammers fight against "black flying" drones?

Drones "black flies" appear frequently, and some people maliciously use them to take photos illegally, and some people illegally transport items. If it falls, the consequences can be imagined. In order to strengthen the control of drones, laws and regulations are also constantly improving. In addition, defensive countermeasures in the region are also necessary. Here, "black flight" can be prevented by a drone jammer countermeasure system. How does the UAV jamming countermeasure system realize the confrontation against "black flying" UAVs?

The use of suppressive radio jamming and deceptive jamming is the fastest, most effective, and least expensive technical means compared to slow, slow drones. The drone UAV jamming countermeasure system uses wireless signals to suppress the remote control signal link, data transmission signal, and GPS navigation signal of illegal UAVs, making the UAV out of control and unable to continue flying according to the operator's instructions. Usually, the main frequency bands of consumer-grade civilian drones are 1.5GHz, 2.4GHz, and 5.8GHz, these three frequency bands. In principle, as long as the amplitude of the radio suppression signal is strong enough that the frequency can completely cover the frequency of satellite navigation, then the drone will lose the ability to navigate automatically.

Since the frequency of UAV communication data and navigation signals is public, the drone signal jammer system only needs to create a frequency band with the same frequency and high enough amplitude to achieve the suppression effect. Therefore, this simple and crude technique is often the most effective.
