Jamming GNSS signals is illegal in many countries. Various international regulations exist that prohibit the use, manufacture, and sale of jamming devices. There are also various standards relating to GNSS anti-jamming technologies. ...

The future of GNSS will likely involve more precise and reliable positioning, requiring robust anti-jamming techniques. As technology progresses, anti-jamming techniques are expected to become more sophisticated and effective, involving advancements in fields like artificial intelligence and machine learning. ...

Some anti-jamming techniques include null steering, beam steering, adaptive antennas, and direct power control. More advanced methods involve GNSS signal encryption and authentication, Frequency Hopping Spread Spectrum (FHSS), and cognitive radio techniques. ...

GNSS jamming can disrupt several sectors including aviation, maritime, automobile, telecommunications, and finance. Beyond these sector-specific implications, GNSS jamming can pose broad societal risks related to public safety, national security, and the economy. ...

Jamming works by broadcasting a stronger signal on the same frequencies used by GNSS signals. This can easily be achieved because GNSS signals, by necessity, are relatively weak by the time they reach the Earth's surface from the orbiting satellites. ...

GNSS jamming is the disruption of GNSS signals due to interference by other stronger signals broadcasted on the same frequency. This can lead to unreliable positioning data or a complete loss of GNSS signal reception. ...
