30.03.2022 Calibration of passive hydrogen maser CH1-1007 in FSUE VNIIFTRI

Passive hydrogen maser CH1-1007 successfully passed calibration procedure in Russian Metrological Institute of Technical Physics and Radio Engineering (FSUE VNIIFTRI). Measured average values of relative frequency difference and frequency stability (Allan deviation) drastically outperforms the values declared in the specification. Calibration certificate approves high accuracy of the instrument. Passive hydrogen maser CH1-1007 is the most mass-product instrument of Vremya-CH, it has export analog the model VCH-1008.



24.12.2021 New system for Kazakhstan based on passive hydrogen masers VCH-1008

Vremya-CH JSC, with the participation of our representative in the Republic of Kazakhstan Madina LLP, carried out the modernization of the State standard of time and frequency at Kazakhstan Institute of Standardization and Metrology. The etalon complex based on the passive hydrogen masers VCH-1008 has been put into operation. The etalon complex contains a system of internal comparisons produced by Vremya-Ch JSC. External comparisons are carried out by the receiver of time and frequency signals GTR55, which has passed high-precision calibration in VNIIFTRI FSUE.



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!



22.09.2021 

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.
