GPS Jamming
GPS jamming is the act of using a radio frequency transmitter to intentionally block or interfere with GPS signals. This prevents GPS receivers from accurately determining their position, navigation, and time.
TECHNICAL DEFINITION
GPS jamming is a form of electronic warfare (EW) and navigation warfare (NAVWAR) that involves transmitting interfering radio frequency (RF) signals to disrupt or deny Global Navigation Satellite System (GNSS) services. This counter-space technique targets receivers, degrading an adversary's access to critical Positioning, Navigation, and Timing (PNT) data for munitions, vehicles, and communication systems.
BACKGROUND
GNSS jamming, including GPS jamming, is an act of communications interference to overwhelm global navigation satellite system (GNSS) receivers with powerful radio signals that drown out the navigation signals from GPS, GLONASS, BeiDou, or Galileo satellite constellations. It renders the receiver unable to calculate its position or time accurately. A common tactic of modern warfare, such jamming can disrupt various GNSS-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.

USAGE NOTE
This term is frequently used in discussions of electronic warfare and asymmetric threats, as jammers can be small, inexpensive, and effective.
