OVERVIEW: Electronic warfare systems designed to disrupt or deny satellite navigation signals broadcast by the Russian GLONASS constellation, affecting the accuracy or functionality of dependent systems.

GENERAL DESCRIPTION: These jammers emit targeted radio frequency interference in the L1 (1602 MHz) and L2 (1246 MHz) bands used by GLONASS satellites. Systems range from portable tactical jammers to vehicle-mounted or airborne platforms capable of creating wide-area denial zones. Most GLONASS jammers utilize narrowband or barrage jamming techniques and may also target other GNSS systems (e.g., GPS, Galileo, BeiDou) simultaneously. Advanced versions employ digital RF memory (DRFM), signal spoofing, or beam-steering to increase effectiveness and survivability in contested environments.

ROLE SUMMARY:
Category: Electronic Countermeasure (ECM)
Primary Use: Navigation signal denial/disruption
Function: RF jamming (GLONASS L1/L2 bands)
Platform: Ground vehicles, UAVs, aircraft, static stations
Integration: Standalone or networked with EW command systems
