GPS Jamming

BACKGROUND

GNSS jamming, including GPS jamming, is an act of overwhelming global navigation satellite systems (GNSS) receivers with powerful radio signals that drown out the signals from the GPS, GLONASS, BeiDou, or Galileo satellite constellations. It renders the receiver unable to calculate its position or time accurately. Such jamming can disrupt various GPS-dependent devices, from vehicle and aircraft navigation systems to precision agriculture and mobile phone networks. In civil aviation, GPS jamming can disrupt ADS-B transmission. GPS jamming is a particular type of GNSS interference.
