Russia has created a complex that synchronizes digital networks in the event of radio-electronic interference

A device that allows digital networks to operate in conditions of radio-electronic interference, providing them with additional synchronization, was created by specialists from the All-Russian Research Institute of Physical, Technical and Radiotechnical Measurements (VNIIFTRI) of Rosstandart.

Satellite navigation equipment is used for synchronization systems in many areas. These include digital television systems, cellular and global data transmission operator systems, and global alternating current networks.

Disruption of digital network synchronization may occur as a result of external electronic and simulated interference. Electronic interference is electromagnetic radiation, which can be of artificial or natural origin, i.e. it can occur from various electronic devices, including household microwave ovens, power lines, radio stations, data transmission modems, as well as from lightning and thunderstorms.

The term "simulated interference", as explained to "MK" at VNIIFTRI, should be understood as "copies of signals", as a rule, unreliable. They can arise both for natural reasons during the propagation of satellite signals, and be created artificially.

According to the institute's general director, Sergei Donchenko, any failures in synchronizing time signals can lead to serious losses and disruption of services, affecting data transfer speed and security.

In order to increase the stability of domestic communications to external influences, scientists have created the "Synchro-1T" complex. In essence, this is a device that receives navigation signals from satellites and, due to the ultra-miniature frequency standard operating on rubidium atoms, maintains continuous storage of time information and provides consumers with its precise signals. This generator ensures stable formation of the time scale, regardless of external interference.

The complex generates a high-precision signal every second and can work with conventional GNSS antennas, requiring only periodic reception of a signal from at least one satellite to maintain the necessary synchronization accuracy.

MK Reference: GNSS antennas are the Global Navigation Satellite System, such as GPS and GLONASS, used to determine the location at any point on the earth's surface using special navigation or geodetic receivers.

For example, it can provide mobile communication for a certain period of time even in the absence of clear satellite signals. However, for this, "Synchro-1T" must be installed in close proximity to the phone being used. An analogy to it can be a digital television decoder, which is connected to a TV set to use digital television broadcasting.

For now, according to the developers, this synchronizer is not consumer equipment; it is intended only for critical infrastructure facilities.

Today, the complex is being tested under real operating conditions.
