Jammer resistant drone designs spark search for countermeasures
The Russia-Ukraine conflict has driven another stage of evolution for drones and the counter measures to defend against them.
Indra develops counter-UAS shield system
Indra has developed a counter-UAS tool that can be integrated with anti-aircraft defence systems to enhance the protection of military bases and installations, the company announced on 28 May.
The Anti RPAS Multisensor System (ARMS) can work both independently and autonomously, and integrated with anti-aircraft systems. The system can cross-reference data and rule out all correctly identified objects, focusing only on those that may pose a real risk, including the presence of small UAS kilometres away.
The system combines different sensors, including radar, radio frequency detectors and infrared cameras, increasing and reinforcing its ability to detect and identify threats. It features advanced countermeasures to disrupt and saturate the UAS’ communications, along with its location and navigation systems. It also uses spoofing techniques to distort the real GPS signal, hindering or blocking its ability to navigate.
The ARMS command centre incorporates intelligence tools to identify the type of UAS in order to choose the most effective countermeasure. The operator can take manual control or schedule an automatic reaction if an UAS goes beyond the established limits, ensuring a constant defence of installations.
The company has secured a military customer for the system in the Asia region.
