Satellite Jamming
Satellite jamming is when a device on Earth or in space intentionally sends out strong radio signals to interfere with a satellite's communication, making it unable to send or receive information properly. This disruption can prevent the satellite from performing its intended functions, such as navigation or data relay.
TECHNICAL DEFINITION
Satellite jamming constitutes a form of electronic warfare (EW) involving the deliberate transmission of electromagnetic interference (EMI) to disrupt, degrade, or deny a target satellite's uplink or downlink communications, thereby neutralizing its operational capabilities for critical military, intelligence, navigation (e.g., GPS), and communication services.
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.

USAGE NOTE
This counter-space capability is primarily used in military conflicts to blind or disable an adversary's space-based assets, but it carries significant risks of affecting non-target systems.
