Rosel has started supplying the Dvina-100M drone suppression systems. The device was created in view of new threats coming from UAV evolution and is designed to protect large manufacturing and critical infrastructure facilities such as airports or railway stations. The product is able to counter a drone swarm and provides a safety dome covering several hundreds of meters over the protected site. 

The Dvina-100М is designed to provide electronic countermeasures against UAV control and data transmission channels, and global navigation satellite systems at ambient temperatures from −40 °C to +50 °C. The device functions in a wide frequency band and has several fixed and quick tunable jamming bands. It can successfully counter various types of UAV and suppresses, in particular, frequency hopping drones. 

The product functions effectively together with specialized radio monitoring systems. These systems provide information about the properties of signals used by a drone that allows the device to form response jamming at this particular frequency and with the same data transmission concept. Such joint operation totally prevents UAV from keeping in touch with the operator or receiving correct data regardless of the protocol and frequency used by the drone. Thus, a flexible system is provided to oppose single or multiple targets, and complex devices with combined control channel.
