At the "Digital Industry of Industrial Russia" (CIPR-2025) conference, Rosel Holding (part of the Rostec State Corporation) for the first time demonstrated the TsSCHV-2021 cesium frequency and time standard – a unique device designed for high-precision synchronization of digital communication systems and scientific research. The development is entirely domestic and is intended to replace imported analogs from the USA and Switzerland.
The device generates ultra-stable frequency signals that are used to calibrate telecommunications equipment, including mobile networks, data centers, navigation, and space systems. The device is based on an atomic-beam tube with cesium-133, which ensures long-term stability and accuracy.
In the modern world, the accuracy and reliability of time and frequency measurements play a crucial role in various industries: from telecommunications to the aerospace industry. That is why it is important to create domestic devices that do not depend on imported components. The cesium frequency and time standard of NPP "Istok" named after Shokin was developed based on the existing extensive experience in creating special-purpose communication standards and optimized for civilian customers. All main components are produced directly at the enterprise.
According to the developers, TsSCHV-2021 meets world standards and has a service life of at least 10 years. The production of key components is localized at NPP "Istok" named after Shokin, which eliminates dependence on foreign suppliers.
