HPEM System from Diehl Defence Protects Against Mini-Drones

By using electro-magnetic pulses instead of radio signals or GPS spoofing, Diehl’s HEPM disables the mini-drone’s controls, causing mission abort and automatically triggering the fail-safe function. (Diehl photo)
Mini-drones represent an increasing threat to both public events and military missions. In particular, autonomously-operating mini-drones enhance the new threat from the air.

Countermeasure systems based only on interference with radio signals as well as GPS jamming/spoofing do not provide reliable protection.

By contrast, the HPEM (1) counter-UAS system developed by Diehl Defence acts directly on the control electronics of mini-drones by means of electromagnetic pulses, thus causing mission abort.

This means: regardless of the control method used (autonomous or radio-controlled), the mini-drone becomes inoperable upon impact of HPEM pulses at distances of up to several hundred meters and triggers the fail-safe function.

Diehl's counter-UAS system provides the possibility of scalable range and the ability to also intercept entire swarms of mini-drones simultaneously.

Diehl's HPEM systems which do not cause harm to individuals are already being used for stopping cars and protecting large events (Olympic Games and summit meetings).
