Hackers never have to be picky about the equipment they research and experiment with, so it's not worth buying. Although the GPS satellite orbit altitude of 20,200 kilometers is not as high as that of the communication satellites in geosynchronous orbit, it is still far from us. Given the distance and size of the antennas on most GPS devices, it's not surprising that the signal received from them is very weak. So much so that it is usually weaker than noise. Only very clever algorithms and a little magic can make your phone hear the whispers of the stars and turn them into something akin to useful information. It's the fragility of this signal that makes it possible to make such a low-cost jammer.
Interfering signals can be caused by mechanical or electrical interference. To suppress such a signal, not much is needed. Note that the device isn't trying to mimic GPS satellites - it's just broadcasting spam, loud enough that the real satellites can't be heard. Of course, our first thought is to come to a drone competition or exhibition, turn on the jammer, and send everyone the business card of the drone repair shop. It turns out that interfering with WiFi, Bluetooth, or Zigbee signals is not difficult at all. All you need is a simple $15 dongle that you can get on Amazon. It connects to a computer or Raspberry Pi. The base antenna has a range of 80 meters. signal jammers have been actively used by attackers. For example, car thieves use portable jammer to prevent the car from locking, and GPS jammers block signals from anti-theft systems (after the car is stolen).

So I recently tested these little GPS jammers that plug directly into a car's cigarette lighter socket. With the wide variety of car tracking devices on the market today, it's no surprise that some people are concerned about how well their vehicles can be tracked. Finally, there is another option called a "shield" or "jammer", which works in a similar way but has slightly different designs and technology inside, which makes it other countries outside the US (often using different frequencies) harder to use them. However, a small disadvantage is that this strategy is limited to jamming frequencies. Tracking is often difficult because it is difficult to pinpoint the specific frequencies affected during a speckle attack. Speckle interference is a concentrated symptom of attacking a particular channel or frequency. There are three types of noise interference: speckle, sweep, and barrage.
But even if you're not sure if you want to block GPS tracking in your car, there's one important point to remember: it can be done! If you Google long enough to find interesting electronics to splurge on, you're bound to be recommended all sorts of dubious electronics. Shipping in the US is under $10, and in my opinion, this device is perfect for opening it up in the name of science. You might be wondering what legal uses this gadget has. The only reason you'd want to interfere with the GPS signal around your device is if you're trying to get away from something you shouldn't. Maybe you're driving a tracked company vehicle and want to take a few hours of naps in the parking lot, or maybe you want to turn off the built-in GPS of a stolen car so you have enough time to get to the workshop. However, we won't focus too much on the potential malicious causes of such devices.
The jammer is so harsh that it completely overwhelms the drone signal at 300 meters, even without a directional antenna. When the Soviet Union broke away from power, Western militaries generally had more traction and control over innovative technologies. After the end of the Cold War, things began to change. During the Cold War, transmitters from the Soviet Union and the West even participated in a "power race" with drone jammer trying to increase their broadcast power. In addition to preventing messages from reaching the target country, interference by broadcasters was common at the time. By doing this, anyone who wants to track you via satellite won't be able to because their signal simply won't get through! Signal jamming was common during World War II and the Cold War.
If a signal amplifier is installed, the working distance of the jammer can reach about 120 meters. The second method is to use gps blocker, which does almost what its name implies: it blocks all unwanted signals from satellites orbiting above us. This means that if someone tries to track your location, they won't be able to get any information from it because everything will be confused. The first is to use a GPS jammer, which basically interferes with the signal your phone receives from satellites in the sky. If you want to block GPS tracking, you can do it in several ways. Burglars use such jammers to block cellular service during illegal entry into apartments.
