Locally-produced "Sgarsh" jamming device presented at Army 2017 in Russia.
The EW device is used designed to suppress the signal from navigation satellites such as GPS and GLONASS. In such conditions, an appreciable part of modern military equipment (especially precision ammunition) loses so many of its capabilities, and the same unmanned aerial vehicles (UAVs) completely lose the ability to navigate in space (for a while they can be driven by an inertial system, but its low accuracy does not allow it to navigate for more than a few minutes, especially if there is wind). The Armenian electronic warfare system (EW) is capable of operating in two modes, depending on the connected antenna - either by drowning the signal in a circle with a radius of up to 30 km (according to the developer), or in the sector of 60 degrees horizontally and 40 degrees vertically. In the directional mode, according to the Armenian expert, the GPS signal can be silenced at a range of up to 60 km. The system itself is small in size and mobile enough. In mountainous terrain, when installing antennas at altitudes, it is possible to turn off GPS far above enemy territory (in directional mode), significantly worsening the coordination and orientation of enemy troops and complicating the effective use of reconnaissance UAVs. The structure of the interference is not simple: it is identical to a useful signal, which often prevents the satellite navigator from determining the fact that it is muffled.
