Electronic signals play a very important role in modern warfare. The stability of the signal is very important for combat. Countries that are studying how to protect the stability of their own signals will find ways to influence the signals of other countries.
Yonhap News Agency said on Tuesday that North Korea has developed a powerful jammer that can jam GPS (Global Positioning System) satellite signals within a range of “more than 100 kilometers.” The news agency said the news about the GPS Jammers was included in the report handed over to the National Defense Committee of the South Korean National Assembly this week.
South Korea’s capital is about 50 kilometers away from the border area. Therefore, jammers with such a large interference range may destroy or destroy GPS signals in Seoul and its surrounding areas. Up to the border cities and regions are full of military installations and equipment, many of which use GPS satellite positioning signals.
The US Navy has entered the final stage of the development of the Next Generation Jammer (NGJ) pod, which will replace the ALQ-99 that has been used since the Vietnam War. The new electronic attack pod is combined with the highly developed electronic attack technology developed by Raytheon, which combines powerful agile beam jammer technology with the latest electronic technology.
Smuggling phone calls is a real problem. They allow prisoners to secretly use drugs, engage in illegal transactions and even organize murders under the eyes of guards and guards. A prison in South Carolina recently detected 35,000 calls and text messages in a 23-day period.
Therefore, FCC Commissioner Ajit Pai and South Carolina Governor Nikki Haley urged preventing prisoners from using cell phones. Prisoners are allowed to make phone calls, but only on special landlines that can be monitored by law enforcement agencies.
