For users who work in the field of geology and geodynamics, exploration and production of natural resources, development of oil and gas fields in the areas of coastal shelves, the use of high-precision navigation measurements is the promising direction. The requirements of this circle of special consumers to the accuracy and quality of navigation-time support is constantly increasing. Increase in accuracy and reliability of navigation measurements can be achieved by solving the problem of controlling the parameters of instability of onboard clocks in navigation satellite systems GLONASS, that makes this work relevant. The main aim of the study is to estimate the instability parameters of onboard clocks GLONASS constellation, determining to a large extent the quality and accuracy of coordinate-time definitions based on satellite navigation technology. The methods used in the study: method of excepting ionospheric delay by dual-frequency measurements, method for estimating the phase ambiguity, H. Hopfield method to compensate the tropospheric delay, method of statistical estimation of navigation clock setoff in the board satellites by the results of trajectory measurements. The results. The authors have proposed the method for estimating the setoff of onboard clock of navigation satellite GLONASS on the basis of hardware-software complex of metrological point at the State service of time and frequency at the Research Institute of Metrology 'SNIIM'. The authors pay the main attention to the use of phase pseudo-distance measurements in estimation of the algorithm as the background information. The typical features of application of such measurements, in particular, the problem of phase ambiguity solution, are selected and described. To obtain the high-precision results, the authors used the algorithms for pre-processing the pseudo-distance measurements to reduce the noise level, use of compensatory amendments to ionospheric and tropospheric delays of a navigation signal. The results of the research are the estimates of onboard time scales offset of the GLONASS constellation and statistical characteristics of the scales representation errors using time-frequency corrections. The advantage of the method is the achievement of high precision due to the use of public secondary standard time, frequency and the time scale VET 1'19. The assess obtained by the authors make the basis for controlling time-frequency parameters of GLONASS navigation field, that is one of the tasks of the State Service for metrological point of time and frequency. The conclusions. The authors propose to use the methods for controlling time-frequency parameters of the GLONASS satellite navigation in order to improve precision characteristics of corrective amendments formed by the network of active base ground stations in Novosibirsk region.

Modern lithographical methods used to create linear measures for nanometer-range dimensions and the main factors which limit the applications of such gages have been analyzed in the paper. Prospects for developing high-precision measures based on an atomically structured crystalline surface (containing monoatomic steps) whose parameters are bound to the crystallographic parameters of the crystal (traceable to the length measure) are shown. A method which can be used to create such measures based on controlling the surface morphology of monocrystalline silicon at an atomic level due to the effects of self-organization arising at the atomically clean surface as a result of annealing in ultrahigh vacuum is proposed. A description of the set of high-precision gages of vertical dimensions STEPP-IFP-1 in a size range of 0.31-31 nm with an error in the whole interval of gages of less than 0.05 nm is presented. The set of high-precision gages after carrying out state testing is included into the state registry of measuring means as measuring type no. 48115-11 (Federal Agency on Technical Regulating and Metrology order no. 6290 of October 31, 2011). © 2013 Pleiades Publishing, Ltd.

A procedure is proposed and experimentally verified for determining the metrological characteristics of temperature calibrators using the fixed point of indium solidification in a miniature ampoule with the aid of a multi-junction differential thermocouple. The procedure allows calibrator-reproducible temperature-value errors to be determined, along with calibrator nonuniformity and instability. © 2016, Springer Science+Business Media New York.

A high-precision transformer bridge for the measurement of capacitance and loss-angle tangent over wide dynamic and frequency ranges is described. The bridge construction is based on the principle of variational calibration, which enables us to exclude the effect of the error sources on the measurement results. The principal measurement error of the capacitance does not exceed 10-6. © 2013 Springer Science+Business Media New York.
