GPSGNSSjamming

GPS/GNSS jamming refers to the intentional or unintentional transmission of radio signals that interfere with the reception of Global Positioning System (GPS) or Global Navigation Satellite System (GNSS) signals. This interference can degrade or completely block the ability of a receiver to determine its position, velocity, and time. Jammers typically operate by emitting a strong radio frequency (RF) signal on the same frequencies used by GPS/GNSS satellites, effectively drowning out the weaker satellite signals. The motivations behind jamming can vary widely, from deliberate malicious intent to disrupt critical infrastructure or military operations, to accidental interference caused by poorly designed or malfunctioning electronic devices. The impact of jamming can range from minor inaccuracies in navigation to complete loss of service, which can be critical for applications such as aviation, maritime navigation, precision agriculture, and emergency services. Detecting and mitigating GPS/GNSS jamming is an ongoing area of research and development, with solutions including advanced receiver algorithms, antenna designs, and the use of multiple GNSS constellations to increase resilience.
