Anti-drone jammer at the Davos summit meeting

World Economic Forum Annual Meeting 2017 in Davos, Switzerland, was busy and the high-altitude resort was as usual highly protected.

With new threats comes new kinds of protection and new types of “guns”.

In these pictures captured by Simon Dawson you can see the HP 47 System.

The HP 47 Jammer can target an unmanned aerial drone to block remote control signals.

Optionally it can be configured to disrupt GNSS (Global Navigation Satellite Systems).

Just as every new technology and comes with a lot of improvements, there’s also potential downsides, and the “drone guns” is a reply to that.

There seems to be two versions:

Counter UAV Jammer

The HP 47 counter UAV jammer has been developed especially for use against consumer UAVs. The system is highly mobile with a weight of below 10kg and enables easy and rapid deployment. Inhibition ranges of more than 500 meters are easily achievable, while posing no health hazard to the operator.

The system is a stand-alone shoulder mounted jammer with directional antennas covering both Wi-Fi channels and all global positioning systems. Frequency bands can be jammed independently to allow for GPS functionality. With GNSS disruption activated, UAVs cannot return to their starting points, but may hover and land or may be captured using net launchers and other counter-UAV technologies. The first units have already been delivered this year and have been used to protect a number of public events.

HP 47 Jammer

The HP 47 jammer features an interchangeable sight including a “red dot” reflective sight and optional telescope, allowing the system to be operated over extended distances. The flexible design allows the remote control and global navigation satellite system jammers to be operated either together or independently. The device uses narrow bandwidths to reduce any unintended disturbance in the surrounding areas.

As you can see on the pictures the system doesn’t seem to require any additional backpacks or external batteries for its functionality.

In these pictures you can see the HP 47 Counter UAV Jammer in use. It was also used during President Barack Obama’s visit in Berlin last year.

The function is that it blocks the signals from and to drones from more than 1,000 feet away, so the drone or UAV can do a “safe” landing. From there it can be either “taken care of” by snipers or collected.

Another company, OpenWorks from the United Kingdom, has developed a solution to fire a net at drones and then parachute them down (picture directly below).

Check out their website and their video, it’s pretty cool to say the least: http://openworksengineering.com/skywall#video

We’ll be back soon with an article about the “real” Firearms at Davos. Stay tuned.

    Davos also hosts an unusually high amount of helicopter traffic, and helicopters and drones don’t play well together. I’m confident that this has been throughly tested on modern glass cockpits and doesn’t interfere with them…of course it has.

  • TheNotoriousIUD

    Im curious if these disrupt active signals only or if it will also disable UAV’s that are not under remote control but programmed for a specific destination.

    • Marco Antonio Gonzalez

      Then again “Optionally it can be configured to disrupt GNSS (Global Navigation Satellite Systems)”

      • TheNotoriousIUD

        Ah. Tricky.

      • RocketScientist

        Onboard inertial nav systems are a thing… Set location at start. From that point on needs no external input to know its location.

        • Blake

          Not for any drone systems that I’m currently aware of. There’s way too much wind drift and inaccuracy in the programmed paths to be guided without GPS input as of now.

          • noob

            correlate the INS with terrain recognizing radar? I think TERCOM was a thing in the cruise missiles in the 70s. Now you could swap out the radar module with a pair of webcams fore and aft for binocular vision and use a hacked PS4 to do machine vision terrain feature recognition.

          • Publius40

            If the drone has laser guidance capability and is flown within a detection range of the laser designator, , , say good night, Gracie.

          • Blake

            We’re talking about consumer electronics here, not military hardware. Yeah I’m sure the military has got some seriously badass drones with incredible capability. But even setting that aside for a moment, we’re talking about a drone’s ability to autonomously navigate without input from the outside. Following a laser isn’t autonomous or without outside data really and plus it’s really not useful. For a bomb that’s job is “follow this laser in a straight line and crash into it” yeah, but not for a drone which has to avoid obstacles on three axis.

    • noob

      If somebody had a grudge against the Davos class, they’d build a drone with a fail safe dead reckoning system using intertial navigation. Or should that be “fail deadly”?

  • 22winmag

    Hey there, week-old news today!

  • Pedenzo

    Absolutely no problem getting around these…you can get RC systems that use anywhere from 35Mhz up to 5.8Ghz…..gonna take a pretty big raygun to jam all of those frequencies…..

  • codfilet

    Globalists don’t want those pesky drones spying on them as they make their evil plots and schemes…..

    • DonDrapersAcidTrip

      you mean capitalists?

      • codfilet

        LOL…yeah,right.

        • DonDrapersAcidTrip

          you actually think capitalism has any inherent ethical or nationalistic quality and it’s just the “bad ones” that are globalists? lmfao

  • Irish1776

    One could fabricate a somewhat less portable poor mans version of this technology if you have an idea of what target operating freq’s you will need to disrupt. Google “UAV spark gap transmitter”.

  • Tom

    What wrong with 12g?

    • User

      That you cant train usual soliders to have absolut perfect timing and skill like some uber clay pigeon shooting experts. And drones also often fly really high.

  • AlDeLarge

    That’s been commercially available for years. You can get a Cheerson CX-20 that does all of that except telemetry for about $200.
