|
| "VREMYA-CH" JScompany is a private company which was founded in 1993 by the team of the leading technical specialists of the Nizhny Novgorod Institute of Electronic Measuring Instruments "KVARZ". |
| VREMYA-CHmain kinds of activity are the development and production of the high performance radio measurement equipment for time keeping and precision frequency comparison: |
- hydrogen maser frequency and time standards;
- rubidium oscillators;
- frequency and phase comparators;
- primary reference oscillators for telecommunication networks;
- special software for time keeping and measurement control and monitoring systems.
|
| The first foreign Customer of VREMYA-CH was Observatoire Cantonal de Neuchatel, which ordered us in 1994 the new model of high stable H-maser physical package. Since that time we actively develop our collaboration, increasing from year to year the number of hydrogen masers, delivered to Neuchatel Observatory. Now, there are very famous Institutes and Scientific centers among our Customers: |
- Physikalisch-Technische Bundesanstalt, Braunschweig, Germany;
- CSIRO Australia Telescope national Facility, Sydney, Australia;
- National Institute of Metrology and Beijing Institute Radiometrology & Measurement in China;
- Institute of Metrology Time and Space and Russian Time Keeping Service in Moscow, Russia;
- Russian Control Mission Center, Korolev, Moscow region;
- National Metrological Centers of Ukraine, Belorussia, Kazahstan and others.
