Drones guide future wars

Perfectjammer 2018-05-23

Drone jammer in future warThe war has entered the drone era faster than expected, and the "overhead dangers" of civilian drones are growing, with the exception of large drones such as the global hawk. At home and abroad, the phenomenon of "black flying" and "flying" has emerged endlessly, which has attracted more and more attention to the problems of safety supervision, such as the take-off and landing of civil aviation aircraft, and the eavesdropping of secret regions. In fact, more and more unmanned aerial vehicle (uav) crime also let the people pay more and more attention to management of the unmanned aerial vehicle (uav). In recent years, some drone terrorist attacks have caused the government departments to pay attention. The government has thought of many ways to deal with this phenomenon

The UAV jammer market is growing rapidly, and drones are now playing a role in aerial photography, mapping, delivery, rescue and other areas. But then there are the "troubles" that affect the order of aviation, the intrusion of sensitive areas... These phenomena, and more also led to the surrounding the rapid development of the derivatives industry, in addition to unmanned aerial vehicle (uav) equipment and service providers, unmanned aerial vehicle (uav) "predators" also benefit a lot from it, this gives an unmanned aerial vehicle (uav) enterprise has brought enormous development opportunities.

Most drones rely on external signals to maintain normal flight activities, including radio flight instructions, GPS signals and so on. There is a saying in the field of electronic warfare: there is no electronic equipment that can not be interfered with, and there is no interference with it. So, in theory, all drones can interfere. It's just more difficult to jam military drones.

Countries spare no effort to study anti-drone technology

The gun can launch directionalradio frequency interference, interference of unmanned aerial vehicle (uav) control system, to cut off the unmanned aerial vehicle (uav) with rear data links or radio communication between control center, the uav autonomous flight, lead to crash, landing, or turn back

The Chinese military has been equipped with the U.S. military to deploy drones to interfere with radiation weapons. Large electronic warfare equipment can even interfere with and capture the enemy's large drones. For example, Russia's "car field" electronic warfare countermeasures system has some powerful functions that are not known to the outside world. The radar system, which can suppress 50 aircraft at a height of 30, 000 meters, can also launch electronic attacks on fighters and drones within 100 square kilometers. In October 2011, Iran captured an American rq-170 "sentinel" stealth drone using the russian-supplied electronic countermeasures system.

Drones do not get enough accurate data on their own coordinates. Therefore, the flight control of the uav is combined with GPS satellite navigation system and inertial navigation system. The drone also needs to know its precise location when taking a photo, so it has a GPS signal receiver installed on it.

As it is, the unmanned aerial vehicle (uav) of GPS receiver vulnerable to electronic jammer gps, lead to uavs can only rely on the inertial navigation system based on gyroscope, cannot get enough accurate coordinate data. Even if there is no precise terrain measurement, with the aid of cameras and video cameras for intelligence will not have any value, at this time of uavs at most is a flying camera, whether from a military perspective, or from the Angle of surveying and mapping of civilian, would mean a loss.

Jamming GPS satellite signals “so the drone's sense of its own location begins to drift away from the truth” is quite doable for both military and commercial drones, because these signals are so weak. “The US military is scrambling right now to reduce their drones' susceptibility to wifi jammer, but it's going to take some time before they've got a satisfactory fix.”

Why need UAV jammer? Why need use the signal jammer? Mobile phone jammers are widely used Cell phone blocker is to prevent cell phone information leakage Application of Jamming Device in Various Countries GPS jammer used in the civil field Mobile jammers will not damage the phone or any other electronic devices Cell phone in prison - a serious problem United States vigorously develops the signal jammer GPS jammers frequently appear in major media in North Korea Russia has achieved significant results in the GPS jammer Use cell phone jammer correctly in school The prison system needs jammer equipment What is a jamming device? Why is there a cellphone problem? Russian GPS jamming technology is developing rapidly GPS jammer used in the civil field We can't avoid the WIFI era Why use public WIFI will to leak personal information? Why is WIFI accused of being dangerous to your health?
