Why US need to pay attention to GPS jammer?

Us military experts said, in order to maximum limit, close to the field of American troops at closed exercises regional GPS signal, which means that a large number of domestic civil aviation flights were seriously influence, this also shows that the exercise is "real" from the side, or not to make such a big sacrifice. The us military believes, in the fight against competitors, the country is likely to have the ability to interfere with the GPS jammer technology, so ready to the worst, in the absence of GPS to help fight, show us the real power. After all, GPS jamming devices have become the direction of modern electronic warfare. At present, this competition has become the main direction of armaments

GPS denial is a becoming a huge issue for American military planners. Peer states, especially Russia, are already putting GPS spoofing and jamming tactics to work during various training events near their own borders. We have discussed this situation in great depth before, and I would suggest you read this article to understand just how deeply the loss of reliable global positioning system data can mean for the U.S. and its allies during a time of war, as well as what is being done to overcome such a monumental hurdle.

US is actively developing GPS jamming technology

The Pentagon has mysteriously tested technology that can jam GPS over a wide area before, and it is likely that this same capability will be put to use in the Nellis Test and Training Range for this Red Flag 18-1. Line-of-sight and distance impact the way in which GPS users, especially other airplanes, operating far outside the training area will be affected.

The fact that the Department of Defense is going to execute wide-spread GPS jamming operations during such a high-end exercise is more proof of just how big of a threat these emerging electronic warfare tactics pose. It will be interesting to see if the USAF admits that the technology was indeed used for Red Flag after the exercise concludes, but considering that there are a whole number of position, navigation, and timing (PNT) technologies being developed in hopes to help overcome the loss of GPS signal jammer during combat, advisories like this one that occur during major military exercises will likely become increasingly normal in the years to come.

if what they are doing is jamming, then if you are getting timing information from a gps receiver and your receiver is in range of the jammer you will get the timing information from the jamming signal, so yes, however the USAF _might_ be including the correct timing information in their jamming signal in order to reduce any side effects of their exercise...

Jamming is denial of service. If the transmission medium is flooded with a high noise floor, digital signal processors will fail to decode any valid values from the band the carrier signal transmits on. Authentic signatures have no utility if excessive noise outshines the entirety of the signal.
