Knowing that it is a GPS positioning device, we use this product to clearly know where we are. GPS has many uses, such as navigation. But, there are a lot of bad guys you know or use it to do the wrong thing. When tracked, property, and even personal security, is threatened.
GPS catches three or more stationary satellites and knows their position, but in order to know the position at a remote location, it collates with the position confirmation of the mobile phone and overlays it on the map, so stop the GPS mobile jammer However, if the power of the mobile phone is turned on, the position of the repeater station of the mobile phone will be known, so the position information cannot be erased unless the repeat box mounted on the mobile phone or the vehicle is turned off.
There are many GPS on your smartphone as a GPS tracking app (current position tracking function). Even if it is installed without permission, there are many cases where the person does not notice it, which is the same as someone constantly monitoring the behavior. With GPS jamming, it protects your privacy from GPS tracking apps.
For example, if you put a GPS mobile phone or a device for location search in the car of your husband, wife or lover (just attach it to the trunk or room of the car or the back of the bumper to complete the work!) You can search your current location. GPS radio barrier You can find a car within a diameter of 20m by rushing to the searched location. You can also find the vehicle in the hotel parking lot. If the subject goes out with someone and detects the whereabouts of the car, it will be possible to know whether the subject is lying.
If you want to block GPS, you can enter the underground parking lot or the multi-storey car park, but if you know that there is no GPS start, the company will ask you "where are you now" and answer it. Keep in mind that if you don't, it's not illegal to be "dismissed".
Some say that people should have the right to buy jammers, and VIP people prevent illegal tracking through these products. The transportation industry always uses GPS trackers to do their jobs, but cell phone jammers prevent them from monitoring their bosses. One of the tools for criminals (not deployed here). For foreign prisoners, escape from shackle surveillance.
The source, familiar with the Ministry of State Security's internal affairs, said these devices have the ability to monitor and interfere with the "drone"'s maneuvering radio waves. However, there is currently no law to regulate PS jammer so it seems that there are many very small jamming devices on the net that can be used simply by inserting them into a cigar socket. As far as I can see in the picture, the contents seem to be unexpectedly simple. Jammers make it impossible to receive GPS signals, so encryption cannot be used. It may be more effective to wrap aluminum foil around the antenna so that it receives only the signals coming from the sky.
For personal safety, I would like to buy a GPS signal barrier to prevent being tracked by bad guys, I think it is still very necessary.
