To meet the demands of UAV countermeasure and satellite navigation denial in key areas, this system adopts omnidirectional satellite navigation suppression and spoofing jamming technologies to effectively deny GNSS devices of UAVs within the coverage area. It is capable of receiving, processing and monitoring the status of satellite navigation signals including GPS, GLONASS, BDS and Galileo. It can generate civil-code spoofing jamming signals for GPS, GLONASS, BDS, Galileo and QZSS. It supports directional expulsion and fixed-point deception of UAVs and other aerial platforms.
