In timing applications, the GPS signal jammer will interrupt the GPS signal, causing the underlying system to lose the ability to synchronize its internal clock, and then lose the ability to maintain synchronization with the rest of the network. Since many critical infrastructure departments require the synchronization of the entire network to be within one millionth of a second, even short-term GPS interruptions can have a significant impact. To make matters worse, when an interruption occurs, there is usually no indication that it is caused by a paper jam. No longer receive GPS signals at all.
Ch Supt Gavin Thomas, president of the Police and Superintendents Association of England and Wales, suggested in an interview that WiFi blocking programs (devices used on ankles or wrists to block the Internet) can be used as a more sensible punishment for computer crimes than prisons. He said: "We must stop using 19th century penalties to deal with 21st century crimes."
This applies to full-spectrum blockers/modifiers and Wi-Fi-based "rouge mitigation" strategies, which disable hotspots by flooding the hotspot and its clients with de-authentication packets. If you want a GPS Jammers or even completely disable the SSID, you will destroy all WiFi networks within the blocker's range and anything else that uses the same spectrum (many things come from unlicensed spectrum). 2.4 GHz and 5 GHz-including most cordless phones). GPS rejection is becoming a big problem for US military planners. Companion countries, especially Russia, have applied GPS deception and deception tactics in various training activities near their own borders. We have discussed this situation in depth before, and I suggest you read this article to understand the impact of the loss of reliable data from the GPS during the war on the United States and its allies, as well as overcoming such huge obstacles.
The fact that the Department of Defense will perform extensive GPS blockade operations in such advanced exercises further proves the threat posed by these emerging electronic warfare tactics. What is interesting is whether the US Air Force admitted that the technology was indeed used for "red flag" after the exercise, but considering that a large number of positioning, navigation and timing (PNT) technologies are being developed, I hope it will be helpful to them. In order to overcome the loss of GPS in combat, similar warnings that occurred during large-scale military exercises may become more common in the next few years.
