GPS rejection has become a major problem for US military planners. Companion countries, particularly Russia, have used GPS deception and jamming tactics in various training activities near their own borders. We have already discussed this situation at length, and I suggest that you read this article to understand how deep the consequences of the loss of reliable GPS data by the United States and its allies during the war could be. To overcome this great obstacle.
The fact that the Department of Defense will conduct extensive GPS jamming operations in such high-end drills proves the threat posed by these emerging electronic warfare tactics. It is interesting to see whether the US Air Force will admit that the technology will actually be used for the "red flag" after the exercise. Given that a large number of positioning, navigation, and timing (PNT) technologies are being developed, she hopes to overcome this problem.
Ch Supt Gavin Thomas, President of the Police Officers' Association of England and Wales, suggested in an interview that wireless jammers - devices worn on the ankles or wrists to block the internet - are more reasonable penalties for cybercrime than prison sentences. He said, "We have to stop using the penalties of the 19th century to deal with the crimes of the 21st century."
In fact, if you want a GPS jammer, you can disable the SSID entirely. This will destroy any WiFi network in range of the jammer, as well as anything else that uses the same spectrum (many things use unlicensed 2.4 and 5 GHz spectrum, including most cordless phones).
In timing applications, signal jammers can destroy GPS signals, causing the underlying system to lose the ability to synchronize its internal clocks and thus lose the ability to maintain synchronization with the rest of the network. Since in many critical infrastructure departments the entire network must be synchronized within a millionth of a second, even short-term GPS interruptions have a significant impact. To make matters worse, in the event of a failure there is usually no indication that this is due to the fault. GPS signals are no longer received at all.
This applies to wifi jammer / scramblers and WiFi-based "rouge mitigation" strategies in which hotspots are deactivated by flooding the hotspot and its clients with de-authentication packets.
