In recent years, many websites that provide “blocking programs” or similar devices have been designed to block communications, and have been greatly increased in vehicles, schools, theaters, restaurants, and other places. These devices are sold under different names, such as signal blockers and military jammer ., which have the same purpose.
Manufacturers of precision guided munitions no longer think that simple GPS guidance systems will always be able to work on their own. Military equipment interference and phishing equipment may threaten future battlefields; manufacturers have noticed and have responded to the threat.
The military and its industrial partners have deployed and are developing various means to ensure that bombs can hit the target, whether or not they mean redundant targeting systems, such as finder for drone jammers, laser guidance systems or camera assist navigation. .
In short, military GPS jammers will make noise so that the GPS receiver near you is overwhelmed and the actual GPS signal is lost. If a precision-guided bomb loses lock within one minute of reaching its target, the result may be catastrophic.
