What is a GPS Jammer? Jul 28, 2022
imageA GPS jammer is typically a small, self-contained transmitter device used to hide a person's location by sending a radio signal on the same frequency as the GPS device. When this happens, the GPS device cannot determine its location due to interference.
https://www.jammer-mart.com/portable-gps-blockers-jammers.html
How GPS Jammers Work:

The user plugs the jammer into the car's auxiliary power outlet.
The unit is placed close to the installed GPS tracker.
When activated, GPS jammers generate jamming signals within a 5 to 10 meter radius to interfere with GPS satellite signal reception.
To understand how jammers work, it is also helpful to understand how the Global Positioning System (GPS) works.
https://www.jammer-mart.com/wireless-video-alarm-5-bands-portable-jammers.html
Where GPS Jammers are Used

Signal jammer from trackers are also known as anti-trackers. Their use is justified when it is necessary to exclude satellite monitoring of your van, motorcycle, car, which can be equipped with tracking devices. Therefore, the position of the vehicle will be hidden and it will allow you to move freely and safely in any direction you choose. This mini GPS jammer is good for your car. It should be remembered that the level of suppression affects the power of the device. The higher it is, the larger the radius of interference on a given frequency, and the less likely the satellite will touch the tracker. If the anti-tracker turns on within 15 seconds, you can be sure that for satellites, your car will remain where the jammer was when the jammer was active. If this device continues to work, the beacon has been unable to transmit data about the movement of the transport. GPS and frequency range do not affect mobile communications. That said, you're free to use your phone and other devices with frequencies that don't match the above while you're on the go.

The main method of UAV countermeasures Jul 11, 2022
imageFor drones that are in an illegal flying state, they need to be reversed through detection and identification technology. At present, drone jammer systems at home and abroad mainly adopt four countermeasures.

https://www.jammer-mart.com/portable-gps-blockers-jammers.html



signal jammer

Interference blocking class
Electromagnetic interference: It can effectively block the communication between the drone and the console, cut off the remote control signal, digital transmission and graphic transmission signal of the drone, so that the drone enters a self-protection state after the signal is lost, so as to achieve forced landing or The purpose of driving the drone.

Navigation Signal Interference: Civilian UAVs usually use satellite navigation and positioning systems to locate themselves. By realizing navigation signal interference, the interference of drones can be blocked. The UAV cannot be accurately positioned after losing the navigation signal, thus affecting the flight control system of the UAV and limiting the flight of the UAV.

Acoustic Interference: Drones have an important component - gyroscopes, to help drones perceive their own flight status. The drone maintains its own balance through feedback from gyroscopes and control systems. Therefore, if the normal working of the gyroscope can be broken, the drone cannot work properly.

Destroy the class directly
Missiles, laser weapons, microwave weapons, fighting drones, conventional firepower, etc. can all conduct directional attacks on drones to achieve the purpose of directly destroying drones.
https://www.jammer-mart.com/wireless-wifi-bluetooth-jammer.html
However, this method requires high precision and high cost, as well as collateral losses due to drone crashes. Therefore, it is almost impossible to directly destroy UAVs in the civilian field.

Intercept capture class
Another countermeasure is interception and capture from the ground or air. The main methods include: capture net, drone capture, eagle capture, etc. It is more common to use a launcher to eject the capture net, but this method has limited range for the drone. In addition, large drones are used to capture small drones, and large 8-axis drones are used to capture small drones with a huge capture net underneath.

However, this method is difficult to control, and small drones have advantages in terms of flexibility, so they are not widely used. Also, by training the eagles, the drones are captured and brought to the designated area. In order to intercept and capture drones, drones need to be within visual range, so their range is very limited. With the development of UAV obstacle avoidance technology, interception and capture will become more and more difficult.

decoy control
Navigation signal lure: For civilian UAVs equipped with satellite navigation terminals, by transmitting false navigation satellite signals, the UAV navigation terminal can be deceived and confused, so that it is positioned at the false position preset by the system. No-fly zone, home point spoofing, route spoofing, etc. can be achieved through satellite positioning signal lure.

Radio signal hijacking: At present, the control signals used by drones are mostly 2.4GHz and 5.8GHz and other conventional civilian frequency bands. The radio signal hijacking technology is to first crack the communication protocol of the drone signal, and then send a stronger control signal to the drone to gain control of the drone.

Hacking techniques: Many drones on the market are controlled by mobile phones and tablets, and WiFi signal communication is used between the drone and the remote control, so many mature hacking techniques can be used to hijack the drone.

Cell phone signal jammers keep the exam room in order Jun 20, 2022
The mobile cell phone jammer system is a professional modern communication signal shielding technology, especially in the special environment of prisons and detention centers, which puts forward higher requirements for mobile phone signal shielding technology. Mobile phone signals may vary greatly at different times. Detention centers and prisons are generally designed according to the requirements of the highest signal time, plus this power redundancy, which is competent in high-reliability and confidential occasions to ensure stable and effective shielding effect. Such shielding requirements It is strictly shielded, and it runs continuously 24 hours a year. For such high-demanding special occasions, the purpose of establishing a high-quality mobile phone signal jammer system is to ensure safety and development. Now many schools are busy preparing for the examination room. This is because the most important examination of the year, the college entrance examination is coming soon. Facing this most important exam, many schools are actively preparing what is needed in the exam room, ensuring the normal order of the exam room and meeting the basic needs of the exam room. As a means of signal cheating, they even purchased an exam signal jammer as a countermeasure.

https://www.perfectjammer.com/all-cell-phone-jammers-blockers.html

As a super loudspeaker, the signal jammer releases a "noise signal" so loud that your phone "can't hear clearly", and the "mouth" can't shout a louder "sound" than the shield jammer. To put it simply, the working principle of the signal jammer is not to block the mobile phone signal, but to block the mobile phone signal. It is equivalent to burying useful electromagnetic wave signals in a large number of useless signals, so as to achieve the purpose of interfering and blocking mobile phone signals. Although a mobile phone is a wireless communication device used wherever it goes, there is actually an invisible line dragging it, which is the communication base station built by the operator. Whether our mobile phone is making a call or receiving a call, the first step is to establish a connection with a nearby communication base station. This is why not only the test takers in the test room are blocked by the signal jammer, but the wireless signals around the test room are also interfered, which seriously affects the normal communication use of users in the surrounding area of ​​the test room, resulting in the inability to make and receive calls, Internet access, information sending and receiving unsuccessful, etc. Therefore, once again, a warm reminder, for the flowers of the motherland, please be patient for two days.
