Area-coverage GNSS jammer (network of posts)

Network of GNSS jamming posts that places a 'dome' over an area in which satellite navigation (GPS, GLONASS, Galileo, BeiDou) becomes unusable, to protect sites against cruise missiles, guided bombs and drones. Developed by the Scientific and Technical Centre for EW, in service since 2016; the posts can be mounted on cell towers. Used in Ukraine and repeatedly reported destroyed by Ukraine. Values are manufacturer figures via TASS and Defense Express.
