According to a report in the UK, illegal GPS signal jammers can damage local GPS equipment and cell phone towers. According to a report by TechWeek Europe, the results of the Sentinel study published at the 2012 Global Navigation Satellite System (GNSS) Vulnerability Conference in the UK showed that there are more and more interference incidents. The traffic monitoring station reported 60 violations within six months.
Sean Gallegher wrote in Ars Technica, describing the danger of interrupting GPS signals. Mobile phone systems and even power grids rely on GPS signals for time management. Jammers designed to automatically mask locations may affect other equipment within a range of 100 meters or more. A powerful gps jammer can interfere with signals up to 32 kilometers long. Yes, jammers have caused problems at airports before. They are used illegally in the UK but are legally owned. I didn’t know that a small GPS jammer would cause such a big damage. Why are you blocking GPS signals? If you did nothing wrong, there is no need to worry.
First-hand, I know a person who bought this precision jammer in the photo. I think this is a little over 100 dollars shipped from China. it works. It is killing my dead AT&T iPhone. He killed the Sprint phone. It killed everything except the one device he tried to use. More sophisticated jammers do not cause “noise”, but they record and replay pseudo-random numbers they receive from different frequencies and drift over time. Such car jammers are used by people to protect their privacy without harming important urban infrastructure.
In 2009, the daily GPS failure at Newark Airport was ultimately attributed to the use of jammers by truck drivers, which presumably defeated trackers that enforce safe driving rules. Authorities and warnings but…in the end…this mainly made me want to buy a GPS jammer. The more we allow us to follow the development of public movements, the more we can give the government and enterprises the power to control and monitor. If one day they want to take back some of these powers, the more difficult things will become for the public.
