GROK jammer (GROK J) is an advanced drone jamming system applied to protect critical installations where UAVs need to be detected and defeated at large distances. Thus, even the micro-drones can be neutralized at distances between 2 to 4 kms.
The GROK UAV jamming system is designed to block remote control radio frequencies as well as the frequency bands of GSNS (Global Satellite Navigation Systems) allowing UAVs to reach their final destinations by autopilot.
The radio frequency jamming can be activated automatically upon UAV detection or manually upon supervisor assistance. The robust antenna system consists of circularly polarized antennas (the number of antennas depends on the number of frequency bands).
The GROK drone jammer is customizable depending on the required level of protection, application and geographical location. The frequency band coverage and output power can be adapted upon customer request, which makes it an ideal solution for jamming the control frequencies of UAVs in any circumstances.
The GROK drone signal jammer has a wide range of applications, including government installations, industrial plants, airports, military bases, prisons. It also provides high level of protection against espionage attack and smuggling of drugs and weapons to custodial facilities.
The main features of the GROK drone jammer:
- Coverage of all available civil drones
- Coverage of worldwide GSNS network
- Directional or omnidirectional antennas
- Variable output power
- Drones neutralization from 100 m to several km
- Circularly polarized high-gain antennas to track the UAV and transmit the jamming signal into the UAV’s direction
- Two jamming modes: automatic or manual jamming activation
- Customization of frequency band coverage and output power
- Additional Pan-Tilt platform with antennas (interfaced with the camera or radar)
When the GROK UAV jammer is used together with the GROK drone detection radar or thermal imaging cameras the jamming is activated automatically whenever the UAV is detected. This allows to position the jammer antenna directly on the detected UAV and precisely transmit the jamming signal into the UAV’s direction avoiding collateral damages.
