Dvina-100M (drone defense system)

History

2025: Product Announcement

In September 2025, the Rosel holding began supplying Dvina-100M anti-drone systems designed to protect large production enterprises and critical infrastructure from unmanned aerial vehicles. The new device is capable of creating a security dome with a radius of several hundred meters above the protected object and resist attacks by swarms of drones.

According to TASS, the system was developed taking into account new threats associated with the evolution of unmanned technologies. Dvina-100M is designed to protect airports, railway stations and other strategically important objects from unauthorized penetration of drones of various types.

The complex carries out electronic suppression of control channels, data transmission of unmanned aerial vehicles, as well as signals of global navigation satellite systems. The system operates in extreme climatic conditions at an air temperature of minus 40 to plus 50 degrees Celsius.

The device operates in a wide frequency range and has a set of fixed and tunable jamming bands. The system is capable of suppressing drones using pseudo-random tuning of the operating frequency, which makes it effective against modern protected drones.

The Rosel holding noted that the illegal use of drones is acquiring new forms and methods, including expanding the frequency range and control over cellular communications and GPS channels. To counter such threats, the company is constantly modernizing its suppression systems by expanding the frequency range and increasing the spectral density of the signal.

Dvina-100M effectively operates in conjunction with specialized radio monitoring tools that provide information on the characteristics of drone signals. Based on the data obtained, the system generates targeted interference precisely at the frequency of operation of a particular drone.^[1]
