Ukrainian company Infozakhyst has expanded the capabilities of its Pluto drone detection and warning system. The complex can now detect mesh modems that Russian forces use to build signal-relay networks between unmanned aircraft. The company reported this on social media.
According to the developers, mesh modems have begun to be used on a large scale to build chains for relaying signals between Russian drones. Previously, Ukrainian specialists recorded them on drones of the Gerbera, Shahed/Geran, Molniya and V2U types.
A mesh network is a way of building a wireless network in which devices can not only receive and transmit information, but also relay it for other participants. In such a system, each connected device effectively becomes a separate node in the network. In the case of drones, this means a UAV can pass a signal from an operator to another aircraft, either directly or via several intermediate drones. This creates a communications chain that is not limited to a direct radio link between the operator and a specific UAV.
Adding mesh-modem detection to Pluto makes it possible to expand the range of signals the system can use to identify potential aerial threats. The developers say this will help detect drones sooner and improve users’ situational awareness.
Another new feature is the ability to monitor Pluto remotely via a configured VPN network. This allows Pluto to be integrated into a remote surveillance and control system, enabling personnel to work outside the danger zone and receive the necessary information at a distance.
Pluto is a signals intelligence (SIGINT) system designed to detect and warn of drone activity. According to the developers, the complex has an operating frequency range of 500–6000 MHz and can detect objects at distances of up to 70 km. Pluto can scan the band about 50 times per second and can operate continuously for up to four hours. The system detects signals by decoding communications channels and matching them against its existing database.
