The application of uav jamming in modern city

Drone Jammer was designed to neutralize the flight unauthorized Drones/Quadcopters by jamming their downlink signal. It has unique software which allows quickly detecting the drone and jamming the hostile drone from ranges of up to 4km (with special dedicated antennas). The below provides technical description of the system.

It wouldn’t make for nice propaganda, but I think those inconspicuous anti-drone (and also anti suicide vest) cell phone jammer inside civilian trucks are far more effective. Though that’s also probably happening in Turkey.

In this modern society, with the fast development of internet, the function of computer and mobile phone has developed, too. People have not only regard them as the basic communication tool, they have treated them as the necessity even best friends in their daily life. They can do lots of things in it. Especially when we welcome the coming of smart era, smart machines, smart mobile phones, smart robot, etc. While behind the smart devices, people become more lazy, more indifferent, more cold and more strange. Sometimes we really need such selectable cell phone signal WiFi GPS jammer to get us back to the reality life.

The GPS signal jammer works by sending out its own signal on the same frequency as the GPS unit, a noisy signal that prevents it from receiving or transmitting any useful information, either in bursts of sound or a continuous wave.

British drone users will have to take a multiple-guess quiz before using their Christmas toys this year, while drone users appear to have, once again, got around pre-eminent drone maker DJI’s software-based flight restrictions.

The Civil Aviation Authority’s Tim Johnson, a policy director, chipped in to say: “We welcome any initiative that reinforces the importance of safe and responsible drone use.”

Last year the British government announced that it is Doing Something™ about the perceived threat of drones in the hands of amateurs. This amounts to mandatory registration and safety tests – in effect, licensing. It appears that DJI is hoping its multiple-guess quiz will be incorporated as the testing element of the British licensing scheme, which would put it at even more of a commercial advantage against its rivals.

That even state intelligence services have had difficulty in determining the source of the jamming and whether or not it was deliberate, highlights how effective these tactics can be even during an uneasy peace. With electronic and cyber assaults, Russia has found an effective way to disrupt the military and government activities of its regional opponents while maintaining a surprising amount of plausible deniability.

GPS disruption isn’t limited to jamming, either. There are increasing reports that the Russians have been expanding their ability to spoof the system’s signals, point receivers at the wrong locations. In June 2017, we reported on the U.S. Maritime Administration’s report about such incidents in the Black Sea in which ships’ navigation equipment was showing their location miles inland. Other reports of location errors had earlier cropped up in Moscow among players of the popular cell phone game Pokemon Go, which relies on a mobile device’s GPS-enabled location services.
