An aviation source told The Insider that the reason for the lack of aircraft trajectory data could be Internet interruptions, as well as targeted actions by the authorities.
“It could be signal jamming,” the source says. – Aircraft with ADS-B transponders broadcast their identification data as well as their 3D coordinates (altitude, longitude and latitude) at 1090MHz or 978MHz. Stations installed in different parts of the world send this data via the Internet in real time to a server, where it is processed so that users can track flights through the appropriate interface.
If we’re just talking about why this happened, then yes, theoretically the signal can be muffled. But completely jamming the signals from the transponders is to put passenger ships at risk. I can’t believe that the authorities will do this. Most likely, there is a point disconnection of transponders of specific aircraft or problems with the Internet through which Flightradar24 receives data. “
