Why the US continues to focus on GPS jammers？

　　U.S. military experts said that to the maximum extent, during the closed exercise, there were regional GPS signals near the battlefield of the U.S. military, which means that a large number of domestic civil aviation flights are in serious condition, which also shows that this exercise is "real". Still don't make such a big sacrifice. The U.S. military, believing that the country is likely capable of jamming GPS jammer technology when fighting a competitor, is willing to play the worst without GPS to help us demonstrate true strength.

　　GPS jamming has become a major problem for U.S. military planners. Peer countries, especially Russia, are already operating near their own borders using GPS spoofing and jamming tactics in various training campaigns. What a huge hurdle for the United States and its allies to lose reliable GPS data during a war.

　　US is actively developing GPS jammers technology

　　The Pentagon has been mysteriously testing technology that can block GPS ahead of large areas, and it's likely that this capability will also be used on test and training ranges. Line of sight and distance affect GPS users, especially the way other aircraft operating outside the training range are affected.

　　The fact that the Department of Defense will conduct extensive GPS jamming operations in such a high-end exercise is further evidence of the level of threat posed by these new electronic warfare tactics. It will be interesting to see if the USAF will admit after the exercise that the technology is actually used for red flags, but given that quite a lot of positioning, navigation and timing technology loses GPS signal jammers in combat, things like that show up in major military exercises The recommendations are likely to become more common in the coming years.

　　If what they're doing is jamming, then if you're getting the timing from the GPS receiver and your receiver is within range of the jammer, you're getting the timing from the jammer, so yes, but the USAF _may_ Include correct timing information in their jamming signal to reduce any side effects of their movement.

　　Interference is a denial of service. When the transmission medium is flooded with high levels of noise, the digital signal processor cannot decode the effective value from the frequency band broadcast by the carrier signal. The information in front of you is useless when too much noise overwhelms the entire signal.
