Gps blocking device
A GPS jammer is a blocking global positioning system device that blocks signals by operation. Jammers can operate on the same or adjacent frequency bands, preventing normal radio signals from being properly received and rendering them unusable.
The GPS satellite is about 20,000 kilometers from the earth's surface and its transmission power is relatively low. Therefore, only a small amount of jamming energy is needed on the ground to temporarily block the GPS signal. Even a small GPS jammer can disrupt the signal in a restricted area of about 2-10 meters. GPS Interference is an enhanced GPS location spoof that sends the wrong GPS signal to the "enemy" by pointing the wrong route.
