The government eavesdropped on our mobile phones and their locations

　　The government keeps following us.GPS jammers is usually (not always) a micro device that can be plugged into the 12V power socket of the car, and is usually called "car cigarette lighter". Once plugged in, it will begin to broadcast some kind of noise at the same frequency as the GPS device, thus creating interference and preventing the GPS receiver from determining its exact location.

　　If you want to stay away from the radar and stay there, the GPS jammer is your best choice. This is where GPS jammers can help. Although this may sound like a commendable effort to combat the spread of the coronavirus outbreak, we all know that After all this is over, the information collected can and will be used against us at a later stage. A recent example is the privacy issue of coronavirus and tracking around infected persons and their whereverabouts, so that others can be reminded to avoid contact with the previous group. GPS jammer or GPS interceptor is a device that interrupts any communication between GPS satellites in space orbit and receivers placed on the earth.

　　These satellites constantly send signals. This is an invasion of our own privacy. Deep down, we know this, but there is no way to prove it. Let's not deceive ourselves. As you can see, the GPS interference is implemented in the same way as the mobile phone interference: by transmitting similar signals at the same frequency but with higher output power, the signals transmitted by satellite (for GPS) and mobile phone tower/site (for mobile phone) are interfered in a way that the receiver cannot receive .

　　The receiver can be a GPS tracker, a smart phone that supports GPS, a satellite navigation system, etc. By eavesdropping on our mobile phones and their locations, the government can learn about our behaviors, including our social network clues, sexual relations, political activities, religious beliefs, and physical activities in the past hours, days, months, and even years. Portable jammers are always useful when you suspect that government officials are tracking you illegally. Although illegal, you can buy various types of cheap GPS jammers on , such as physical shielding, Wi Fi/Bluetooth jammers, remote jammers, spy camera jammers and UAV jammers, to name a few. However, before you go out to buy, you need to know something.

　　In addition, there are also moral and legal issues, because obtaining such data can reveal many private details of our private life, which is more than we initially thought. GPS works thanks to radio signals from satellites. When you turn on the location service on your smartphone or the satellite navigation system in your car, these devices will receive signals from four or more satellites to determine the location.
