Russia Develops Hi-Tech Jammer to Shut Down GPS
In other words say goodbye to GPS-guided munitions -- the only problem, it also jamms Russia's GLONASS
An integrated jamming system to screen strategic facilities from cruise missiles, smart bombs and drones using GPS, GLONASS, Galileo and Beidou global positioning systems for homing has entered service with the Russian armed forces, the newspaper Izvestiya wrote citing a Defense Ministry source in Moscow.
Dubbed as POLE-21, the system consists of jamming modules installed on mobile phone towers and working as a single whole to cover entire areas and making them impregnable to satellite navigation systems.
Besides being powered by a tower’s circuit, the Pole-21 modules also use their GSM antennas as a backup channel for signal control and transmission. “The system has already been successfully tested and is now operational,” the source told the newspaper.
All the four global positioning systems whose signals are effectively deflected by Pole-21 work within the 1176.45 and 1575.42 MHz range. Even a 20 watt transmitter is enough for Pole-21 to jam all signals in this range within a radius of 80 kilometers.
