26.11.2021 Congratulations to Victor Polyakov on the successful defense of his PhD thesis!

On November 24th, 2021, in the State Scientific Metrological Center "VNIIFTRI" Victor Polyakov presented his PhD thesis "Research and development of a hydrogen maser with a single-state selection system for frequency stability improvement", scientific advisor - doctor of technical sciences, Deputy General Director for Science in "Vremya-CH" JSC N. A. Demidov.

Victor has got the candidate of science degree in the specialization 05.11.15 - metrology and metrological support.
Colleagues sincerely congratulate Victor on this important achievement and wish him further success in his scientific work!

On 13th of August 2021 the Cooperation Agreement was signed by JSC Vremya-CH and The P.N. Lebedev Physical Institute, LPI. The main aim of cooperation was defined as carrying out investigations in the field of frequency standards development, laser and vacuum technologies.

The joint group of Vremya-CH engineers and LPI scientists started the development of perspective small-sized frequency standard based on trapped mercury ions for space applications. General aim of the project volume of the standard less than 20 liters, mass less than 20 kg, metrological properties instability less than 5∙10-15 @ 1 day, long-term frequency drift less than 5∙10-17/day, in-orbit lifetime more than 10 years.


02.06.2021 Active Hydrogen Maser with Single-State Selection System

Vremya-CH JSC has developed a new model VCH-2021 active hydrogen maser with single-state selection system having frequency stability at one day better than 210-16! Three instruments are under long-term tests now. VCH-2021 is being prepared for serial production.

The Vremya-CH general manager A.A. Beliaev became the winner of the Russian Federation Government Awards in Science and Engineering. The award was given to a team based on SSMC VNIIFTRI scientists, for developing a high-precision complex of quantum time and frequency standards for advanced navigation, geodesic and digital technologies.

03.12.2019 
The signing of the order from general manager A.A. Beliaev to start production of 80 systems of active hydrogen frequency standards for the execution of contracts for supply to domestic and foreign markets in 2020.
