27.06.2005 Delivery of equipment to China
A consignment of Passive hydrogen maser frequency and time standards VCH-1006 has been delivered to Chna and is being installed.

20.06.2005 New facility: License for space work
Vremya-CH obtained a license for space work valid for 5 years on June 10, 2005. Licensed kind of activity is development and production of onboard hydrogen maser frequency and time standards and onboard timing equipment for space radio-telescope.

22.12.2004 New product: LPRFS - 01
Certification of Rubidium Reference oscillator type LPRFS is complete, including application in military defence and security fields.
The instrument is remarkable for its high specifications and high reliability. See information about it in part "Products" in the nearest time.

20.10.2004 New projects: space conquest
"Vremya-CH" company and Astro Space Center of Lebedev Physical Institute of Russian Academy of Sciences signed a contract for development and production of an onboard hydrogen frequency standard for a space radio telescope of RadioAstron project.
The main specification of the hydrogen frequency standard will be frequency stability (Allan variance) for 1000 s not more than 3x10-15.
Delivery of the maser should be performed by the beginning of the year 2006.


23.09.2004 Visits: Chinese delegation
Chinese delegation - specialists from Beijing Institute of Radio and Measurement (BIRMM) and China Xinshidai Company- visited Vremya-CH on September,21-22. The purpose of the visit was signing a delivery contract for Active Hydrogen Frequency Standards VCH-1003A and Precision Frequency Comparators VCH-314.
Signing of this contract is the next step in successful collaboration that appeared in 1997 between Vremya-CH JSC and the leading chinese enterprise in radio measurement and metrology .
