GPS jammer used in the civil field
GPS jammers are commonly employed in the civilian sector.GPS jammers are easy to order from the Internet and have the ability to protect privacy and prevent others from tracking. These products are beneficial and should be purchased. For example, some VIP characters can avoid illegal tracking through GPS tracker. Russian President vladimir putin is said to have been using the device
In North America and Europe, of course, in order to protect personal privacy, this kind of equipment is also required. Because you don't know when your vehicle will be tracked by someone else. After all, GPS trackers are easy to buy.
GPS jamming technology can also be used to manage drones. Professor Todd Humphreys and his team have taken control of an unmanned drone through a GPS spoofing technique at Austin. They used tiny helicopters to disrupt the GPS systems on unmanned aircraft, and then to provide coordinates for drones to move towards their given targets.
It's not the first time a drone's vulnerability has been exposed, it's easy to buy a GPS jammer on the Internet, and then force a drone to crash or other operations. And this signal interference is effective for all unmanned aircraft. The famous davos economy forum has used similar devices to regulate the use of drones, to protect order and safety. Such equipment has played an important role in the success of recent conferences.
In the military field
For now, the military applications of GPS jamming technology are mainly focused on electronic warfare. For decades, one of the principle requirements in electronic warfare (EW) has been to geolocate enemy transmissions. This has given rise to a plethora of techniques for determining location, such as received signal strength (RSS), angle-of-arrival (AOA), time-of-arrival (TOA), time difference of arrival (TDOA), frequency difference of arrival (FDOA), and so on. In a positioning application, we have the reciprocal problem: instead of trying to geolocate a transmitter relative to ourselves, we are trying to geolocate ourselves relative to a set of transmitters. But of course we use the same techniques: GPS is an excellent example of a TOA system.
Russian electronic interference with the Finnish & Norwegian GPS networks began early September, 2017 and was decided to be kept classified by Norwegian authorities until the exact nature of the scenario was determined.
Loss of commercial aircraft GPS capabilities certainly could have resulted in a catastrophic air disaster, but Norwegian Intel believes Russian GPS jamming over Finland/Norway was not the intent of the Russian government nor Russin military.
According to expert analysis, GPS jamming and anti-jamming technology will be the key points in future electronic warfare.
