The price of a frequency jammer is cheap

　　It's nice to see another national document, which includes GPS failure as a network problem.

　　Excuse me:

　　Communication capability between computer telephone jammer and OT system, Interfere with terminal usage equipment (various computers and equipment), and It is possible to enter incorrect data into the system.

　　Challenges include a lack of manpower, chaotic governance at the federal level and information/intelligence sharing. In addition, there are many types of businesses and other government stakeholders, many of whom may have difficulty establishing a reliable cybersecurity plan.

　　Threats to information technology and operational technology systems are diverse. One type of threat is described as passing through the electromagnetic spectrum system.EMS poses a threat to communications and the Global Positioning System.

　　The plan at one point described how the Homeland Security Department predicted in 2016 that if there was no backup system, the loss of GPS signals would cause port operations to stop. It's not a difficult prediction, as the US Coast Guard saw before 2014.

　　Second, the GPS blocker can only prevent the GPS device from tracking the vehicle, and it will not affect the mobile phone. There is no need to worry if your phone is in your car and the GPS jammer has been installed. Of course, some devices incorporate a GPS mask and a mobile mask, so you should study this model before buying.

　　the price of GPS mobile phone jammers ranges from tens of yuan to several thousand yuan. The price of a portable GPS jammers can be only a few tens of US dollars, while the price of a professional GPS jammer for a high-power remote control can be more than a thousand dollars.

　　The plan describes jamming and spoofing navigation as major problems elsewhere. There are also 14 maritime organizations on how to ask the Commander of the United States Coast Guard to ask questions of the International Maritime Organization (IMO). The International Maritime Organization later described GNSS interference as an emergency and a human security issue.
