Where does the GPS go?
I was driving recently through Novorossiysk and something that often began to fail me GPS-navigator. You go, you go and once the navigator starts to show your location somewhere 500 meters away and is rebuilt by choosing a new route. Sometimes it throws you right into a clean field, and the road is about a kilometer away. Maybe this is of course a software or hardware problem (I will figure out, reinstall), but there is another aspect of this issue.
Maybe there were some military facilities near where GSM signal was suppressed?
There was a lot of information on the Internet, as in Moscow, near the Kremlin, they jammed and replaced GPS in such a way that it threw back at Domodedovo. But look what else there is a chip.
The company Zala Aero (part of Concern Kalashnikov AO) has developed a new satellite signal suppression system, Zala Zont, the company's press service reported. The system was presented at a closed show during the International Military-Technical Forum Army-2018.
Zala Zont suppresses the signals of satellite navigation systems (GPS, GLONASS, BeiDou, GALILEO) within a radius of 2 kilometers, ensuring the safety of ground groups from attacking kamikaze drone aircraft and removing the exact coordinates of the group.
The weight of the Zala Zont system with battery is only 800 g and is placed in a standard pouch for transporting the magazine from the machine. The continuous operation time is 6 hours; for recharging or continuous operation, the system is connected to the 110/220 V network.
