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

11With 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).


TFB recently had an article on the Dronegun. If you missed it you have another chance below:


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