North Korea Massive GPS Jamming Attack

　　North Korea's use of high-power GPS jammers has made such products frequently appear in major media. So what does this thing do, and what other things we don't know about it?

　　Some people say that GPS jammers endanger social security, and in some processing plants, these products with restricted use flow out, so they can be easily purchased online, and these products are not produced to flow to the market.

　　Some people think that these products are beneficial and should be entitled to purchase. For example, some VIP characters can be prevented from being illegally tracked through these products.

　　The transportation industry often uses GPS trackers to track deployments, and jammers gps prevent bosses from monitoring their work.

　　For criminals, stealing cars can interfere with tracking; criminals who are monitored by GPS handcuffs abroad can also interfere with tracking through products.

　　On the whole, because the broadcast signal power of the GPS system is very small, some normal power supply equipment can support the GPS jammer to work without expanding the power.

　　In fact, most people do not need to use such products, because the small jammer can not only block the tracking devices around you, but also block the people around you from using GPS positioning products
