GPS jamming is a particular type of GNSS interference. Under ITU rules, countries are obliged to eliminate harmful interference through GPS jamming and spoofing, but the ITU lacks effective enforcement measures. [2] The ICAO legal framework requires that countries should implement appropriate prevention and mitigation of GPS jamming and ...
Calls can also be dropped if a mobile phone at the other end of the call loses battery power and stops transmitting abruptly. Sunspots and solar flares are rarely blamed for causing interference leading to dropped calls, as it would take a major geomagnetic storm to cause such a disruption (except for satellite phones ).
GPS signals can also be affected by multipath issues, where the radio signals reflect off surrounding terrain; buildings, canyon walls, hard ground, etc. These delayed signals cause measurement errors that are different for each type of GPS signal due to its dependency on the wavelength.

A GPS receiver processes the GPS signals received on its antenna to determine position, velocity and/or timing. The signal at antenna is amplified, down converted to baseband or intermediate frequency, filtered (to remove frequencies outside the intended frequency range for the digital signal that would alias into it) and digitalized; these ...
GPS interruptions in the South from North Korea have occurred for more than a decade, but spoofing appears new, said SkAI, a Swiss company that runs a live disruption map.
The call data (known as intercept related information (IRI) in Europe and call data (CD) in the US) consists of information about the targeted communications, including destination of a voice call (e.g., called party’s telephone number), source of a call (caller’s phone number), time of the call, duration, etc. Call content is namely the ...
In the film Tomorrow Never Dies, a military GPS signal is meaconed to send a Royal Navy frigate off course.. In the novel and miniseries of the John J. Nance novel Pandora's Clock, an attempt to warn the airliner about an impending attack is summarily dismissed as an attempt at meaconing.
