What is the distance for locating and jamming?

Locating distance is 2km and jamming distance is 3km.

What is the frequency range of Hunter?

Jamming frequency of Hunter is between 400 Mhz – 6 Ghz.

How will I update it when needed?

For security reasons it can only be updated manually. The device can not be accessed remotely.

How many kilograms does the XSkyDef Hunter weigh?

XSkyDef Hunter is 6.5 kg.

What is the meaning and difference of IP65, IP66, IP67?

The 6 in IP 6x represents the dustproof level, and 6 is the highest level, which is completely dustproof. The 5 in IP65 indicates that the waterproof level can withstand low-pressure water jets and prevent rain. The second 6 in IP66 means it can withstand high-pressure water jets. IP67 means it can be immersed in water to a depth of 1m for a short period of time.

What are the key indicators of radar?

Working frequency, detection range, detection accuracy, resolution, update cycle, power

What equipment is needed if a drone needs to be forced to land at a fixed point?

1)Portable solution: Hunter+spoofer

2)Fixed solution: radio detection equipment (detection and early warning and radio-level guidance interference), navigation deception equipment (control), radio interference equipment (cooperating with Spoofer and the ability to stop drones), 4 radar+ PTZ camera (providing location information and wireless Human-machine status information - image)

What are the commonly used flight control frequency bands of Hunter?

868MHz, 915MHz, 2.4GHz, 750-1020MHz

What are the signal categories of drones and the functions they implement.

1) Flight control signal, control the flight of the drone

2)Video transmission signal, used to transmit real-time video captured by the camera back to the ground station or display

3)GNGSS signal, used to locate the position of the drone and realize automatic return to home and other functions

What is the jamming power and frequency band of SPS100?

The portable hunter has interference functions and can interfere with drones within a 1.5km range. It weighs 4 kg and can support strikes for 45 minutes on a single battery. Countermeasure power 100w (800M-2G: 40W, 2G-4G: 20W, 4G-6G: 40W). The attack frequency band can be customized through hardware adjustment.

The standard version striking frequencies are:


What is the difference between radar+PTZ Camera and radio detection?

1)Radio detection: including spectrum detection and protocol analysis

2)Integrated 4 radar +PTZ camera: active detection, through the radar transmitting and receiving reflected radio waves, analyzing the position, speed (the radial speed of the flight radar is mainly) and other information of the drone. PTZ follows the guidance of the radar and obtains UAV information from optical angles, such as UAV flight attitude (hovering), UAV type (rotor, fixed wing), and UAV mounting (the angle accuracy obtained is better than radar )

What is the detection distance and FOV of Hunter?

For Phantom 4, the detection distance reaches more than 1km (the distance near the normal line will be shorter), FOV horizontal ±60°, pitch ±20°

What is the difference between Spoofer Area denial and Active defense?

 The essential difference is: area denial triggers the no-fly zone mechanism inside the drone by sending the coordinates of the no-fly zone, while active defense is a strategy that includes sending frequency, direction, acceleration and other information.

Active defense means that the device sends out false signals based on its own position, and the speed direction continues to change, making the drone think that it is in a wind whose speed direction keeps changing, thus triggering the anti-wind logic and making the drone lose control.

Area denial is to send out the latitude and longitude of a real no-fly zone (such as an airport), making the drone mistakenly think that it is in the airport. The drone landed on the spot after 100 seconds.

In what ways can existing company products complete data transmission with C2?

 Navigation deception: wifi connection, LAN wired

Tracer: image transmission, wifi, TypeC wired

Radar: wired network port

Blader: wired network port

If fixed equipment needs to be installed at the dessert, what conditions need to be met?

Waterproof and dustproof

Anti-rust and anti-salt spray corrosion

Electrical insulation

Stable structure and strong wind protection

What are the differences in radio detection between commercial drones and FPV?

 (1) The difference in detection methods is the same as in question 10

(2) The main difference lies in directional detection. Since the detection methods at this stage are based on amplitude and direction detection, FPV orienting is more difficult. The specific manifestations are:

① The 5.8GHz working frequency band of FPV drones is 5500-5950MHz, which is much wider than the 5785-5850MHz of commercial drones.

② Amplitude and direction finding requires one rotation, which takes a long time. The flight speed of FPV is much higher than that of commercial drones, which increases the uncertainty of azimuth movement.

③ The transmit power of FPV image transmission is unstable.

What are the differences in radio interference between commercial drones and FPV?

Mainly manifested as differences in frequency bands (differences in frequency sweep cycles) 

What are the commonly used commercial drones and FPV image transmission frequency bands?

Commercial drone 800/900MHz, 2.4GHz, 5.2GHz, 5.8GHz

FPV 1.3GHz, 5.8GHz analog image transmission

FPV2.4GHz, 5.8GHz digital image transmission
