Federal State Unitary Enterprise "National Research Institute for Physicotechnical and Radio Engineering Measurements" (FSUE VNIIFTRI) is the Main Metrological Center for the State Service of Time, Frequency and Earth Rotation Parameters. The institute has the status of a State Scientific Center of Russia and is among the most important Centers for State Standards of Russia under the authority of Rosstadart.
VNIIFTRI is included in the list of Russian strategic enterprises and is designated by Rosstandart as head organization responsible for metrological assurance of the development, production, testing and operation of weapons and military equipment; metrological assurance of Russia’s nuclear weapons complex; metrological assurance of coordinate-temporal and navigation systems with the objective of achieving the specified accuracy of GLONASS.
VNIIFTRI holds unique measuring, test and experimentation equipment as part of its laboratories’ facilities. The institute, whose premises occupy an area of over 70,000 square meters, is situated outside Moscow in a place well-suited for high-precision measurements and scientific experiments due to the distance from the megacity with its industrial noise and vibration.
VNIIFTRI maintains more than 45 state primary standards and over one hundred and twenty working standards of various orders of accuracy, and calibration and measuring installations.  
 FSUE VNIIFTRI is a national metrology institution (NMI) carrying out basic and applied research for the advanced development of measurement standards in various fields of metrology including measurements of time, frequency, big lengths, and Earth rotation parameters; ionizing radiation parameters; aerosol, hydrosol and powder parameters; electrochemical measurements (pH-metry, ionometry, conductometry); and hardness measurements.
