During airstrikes, smartphone users often encounter problems related to geolocation and time, when mobile devices start showing incorrect coordinates or malfunctions in the time system. These "glitches" are not random, and experts believe that the main cause of such a problem is the use of electronic warfare (EW) equipment, which can even modify or block GPS signals.
Electronic warfare can suppress the signal, but it can also, as an element of electronic warfare, change the signal, forge it. This is simply forging the signal from the satellite to the GPS receiver
Aviation expert Bohdan Dolintse noted that this method misleads the control systems or navigation systems of various devices, including drones, so that they do not correctly determine their location.
And then they either changed their route from the goals they set during launch, or they could have returned to some other area altogether, for example, in the direction from which they arrived
Yakushev explained that in such a situation he sees a mobile phone.
He believes this because there is no authentication, the authenticity of the person transmitting to the transmitter is not verified, so the receiver is like this: thank you for the information, now I am in Kursk. Here is the weather in Kursk, the time
Such geolocation distortions help air defenses filter out false targets during drone attacks. This problem can be easily solved by turning off geolocation.
On November 5, Ukrainians began complaining about malfunctioning smartphone clocks: some users' phones are "rushing." In addition, the wrong location appears on their phones.
The General Staff of the Armed Forces of Ukraine explained the reasons for the disruption of the precise time system in mobile phones during air raids. The disruptions occur due to the use of electronic warfare equipment and the substitution of GPS coordinates.
The General Staff also advises turning off the automatic time update mode on your phone and taking into account that during air alerts, the accuracy of satellite navigation systems may be impaired.
