The interference and shielding of UAV remote control and
positioning signals are realized by transmitting the interference
signals of 900MHz / 2.4G, 5g and various GPS, so as to force the
UAV to fall or return, and create a "no fly zone for UAV". The
interception and interference frequency band includes 2.4G and 5.8G
control signals, GPS positioning and navigation signals, etc. the
straight-line interception and interference distance under normal
environment can reach more than 2500 meters (the actual distance
will fluctuate due to the use environment). After the
jammer is started, the remote control signal of the UAV can be cut off,
and the real-time burst signal and positioning navigation signal
can be transmitted,

Product features;
◎ Bochuang spacetime brand
UAV jammer adopts UHF broadband seamless jamming technology
◎ single channel switching technology controls power output.
◎ high effective power (channel power) and large interference
distance.
◎ effective segmentation only interferes with UAV control and video
transmission frequency, and will not interfere with other
frequencies.
◎ imported devices. The slow start circuit design can avoid the
ignition phenomenon caused by mechanical switch, with high
integration and stable operation.
◎ the built-in battery and plug-in battery are adopted, which can
be replaced at any time. The service life is about 1 hour, and the
battery is rechargeable
Electricity for 4 hours.
◎ four SMA / n-type interfaces for connecting directional antenna
(900m / 2.4G / 1.5g / 5.8G)
◎ one power charging interface (DC24V in)
Operation process;
When all the switches of the anti gun of the UAV of Bochuang
spacetime brand are turned on, the UAV will make a forced landing.
When the GPS is turned off and the 2.4g/5.8g/900m is turned on, the
UAV will lose control. At this time, the UAV will return. When the
2.4g/5.8g/900m is turned off and the GPS is turned on, the
positioning of the UAV is lost. At this time, the UAV remote
control can be controlled.

UAV jammer is specially designed for visual UAV interference. The effective
distance is that the flying hand is about 100m away from the UAV
and the interference is more than 1500m.
Wireless communication must ensure sufficient carrier interference
ratio (signal-to-noise ratio) in order to receive effectively and
complete communication. The Communication
Signal Jammer destroys the reception conditions of UAV and cuts off the
communication connection between UAV and remote control
transmission by generating interference signals with the same
frequency as UAV. Achieve the effect of interfering with
communication.
The interference power is certain, and the shielding radius of
unobstructed space is controlled by path attenuation and remote
control transmission
The signal level is determined jointly. The following table shows
the comparison table of distance and path attenuation. Then the
coverage radius can be determined by the
jammer's output channel power, remote control signal level and coverage
line gain. The following formula:
Pch+Gat-L-FAF≥Prx
Where:
Pch : Minimum channel power output by jammer
Gat : Antenna gain
L : Path attenuation
FAF : Added value of path loss, 6-8db
Prx : Received signal strength
