Primary advantages of “Groza-S” station
1. All-weather 24-hour UAV detection and direction-finding channel using emissions from UAV on-board transmitters, capability of UAV positioning and UAV flight trajectory plotting when two “Groza-S” stations work in a pair.
2. Wide frequency band for UAV-to-GCP control channel detection and jamming (uplink), detecting and jamming data transfer from UAV (downlink)—100 MHz to 6 GHz, covering all possible frequency links (uplinks and downlinks). Great emission power providing greater jamming range.
3. Capability for jamming GPS, GLONASS, GALILEO, BeiDou navigation systems individually as selected by user or all the systems simultaneously.
4. Capability for spoofing GPS navigation receivers (while simultaneously jamming GLONASS signal reception) is the function that is not provided by any other manufacturer worldwide. The function allows for pulling UAV off the protected zone to another zone designated by station operator and force the UAV to crash at the designated zone.
5. Capability to employ the station in a stationary variant (high-rise buildings), on light and heavy vehicles.
6. Integration of three UAV detection, recognition and tracking channels (detector/ direction-finder, TV module, thermal imaging module) when the station is equipped with electro-optical monitoring complex (option). Electro-optical monitoring complex (option)
The Electro-Optical Module is designed for monitoring aerial environment, it allows detection of unmanned aerial vehicles in real time, by day and at night.
The Electro-Optical Complex comprises:
- electro-optical module on rotary support platform (RSP), including TV and thermal imaging observation channel, and a range-finding channel;
- automated operator workstation;
- Interface and secondary power supply.
“GROZA-R” COUNTER-MULTICOPTER RADIO ELECTRONIC RIFLE
Designation: prevention of the small-sized UAVs trespassing the territory of protected facilities.
“Groza-R” fulfills the following tasks:
- jamming of UAV control channels;
- jamming of on-board hardware of GPS, GLONASS, GALILEO, BeiDou satellite navigation systems.
Method of application:
Upon detection of the multicopter within the visibility range, a rifle operator turns on the transmitter power, aims the rifle at the multicopter using the collimator sight and presses the emission activation button. The multicopter is forced to emergency land due to the interference (the required impact time for the forced landing depends on the multicopter type).
