How to Improve Your Signal Jammer Cell Phone Blocker Skills　

　　According to the report of the British Aviation Accident Committee, a British drone crashed into a house and crashed outside due to GPS interference. The 25-pound drone fell from a height enough to cause serious injury or death. Fortunately, no one was present.

　　The second drone sent to the crash site suffered almost the same fate.

　　The incident took place during a routine construction site survey conducted in December using DJI Matrice 600pro. The DJI Matrice 600 Pro is essentially an enlarged version of DJI‘s popular consumer quadcopter. The operator had previously detected that the satellite navigation signal interfered, but this did not cause any serious problems. However, during the last launch, the drone soared to an altitude of one hundred feet and reported a GPS compass error.

　　When you get information about GPS jammers you may wonder what they are and what potential uses they have.

　　Before explaining the GPS jammers yourself, it is best to explain how GPS works. GPS stands for Global Positioning System, a system used by individuals, businesses, and the military primarily for navigation purposes.

　　How Global Positioning System Jammers Work Global Positioning System:

　　The signal is sent to the GPS receiver to determine the position by triangulation. GPS can be found in individual handheld devices and cell phones, vehicle navigation and positioning systems, and in small GPS tracking devices.

　　In this case, the drone will automatically return to manual flight mode and hover in place. It uses an air pressure sensor to keep its altitude, but it doesn't know its movement relative to the ground. It drifts with the wind. Normally, the operator will control the aircraft, but in this case, they will be surprised that the drone sails behind the trees with a strong wind of 15 miles per hour and disappears from the sight and manual control range of the industrial site Outside.

　　The drone remained at the same altitude, but the rising ground meant it was on the roof when it reached a residential area a few hundred meters away. It crashed into the house and damaged its rotor and fell into the garden.

　　Triangulation, in which three different point measurements calculate a position, can be used to determine the position. In the car navigation system, the position of the vehicle is measured by three satellites orbiting the earth. Using triangulation, GPS can transmit the position to the receiver with an accuracy of only a few inches.

　　GPS signals are radio signals that use a specific frequency. In fact, GPS will operate on two main frequencies, one for public non-military use (1575.42 MHz) and the other for the United States. South military only (1227.6 MHz). Since GPS is nothing more than weak radio waves, these waves can be disturbed or distorted with a GPS jammer, although this requires technical equipment and specialist knowledge.

　　GPS jammers were originally developed by the government for military and spy agencies. Areas of use include confusing the enemy in precise locations or where the enemy‘s GPS-guided missiles or bombs fall.

　　According to the British DROPS work safety standards, a blunt object weighing 4 pounds (in this case, the height of the fall) dropped from a height of six meters may even cause injury or death to a person wearing a helmet. The weight of the drone is six times its weight, and there is a correspondingly high risk of injury.

　　The drone operator launched a second drone to search for the crash site because he didn't know where it was. This also caused a signal failure and the second drone landed safely and quickly.

　　Lately, civilians have turned to these devices to protect their privacy in an expanding world with GPS tracking. However, most civilians do not have the technical skills to create their own homemade gadgets as it means a little more than just blocking a radio signal with basic radio interference.
