This paper describes the major milestones in the development of precision measurements of electrical circuit parameters at frequencies of 1 kHz – 300 MHz from the 1950s to the present day. Work on the creation of national standards in this area, as well as of working standards for electrical units, is described. Future developments are discussed.

In 2007–2008, comparisons were made on high-frequency standards of electrical capacity (10–1000 pF, 1–30 MHz) from the Siberian Research Institute of Metrology (SNIIM) and the Czech Metrological Institute (CMI). In the comparisons, we used a precision adaptor developed in the SNIIM, which allows one to pass from coaxial unipolar attaching devices in the standard SNIIM equipment to four-pair joint devices in CMI apparatus.

Test results are reported for road curvimeter of Evenness and Evenness-P together with Wave track measuring carts, and Profile complexes. Simulator testers have been developed for SIRK double track and have been manufactured, where stands allow verification of the parameter numbers with the required accuracy.

A new approach to linear measurements in the nanometric range based on the measurement of the transit time of an electromagnetic wave between two points that bound a linear region is proposed. Frequency methods that make it possible to increase the resolution of linear measurements and improve their traceability in this range are used.

Angular measurements by laser ranging of spacecraft are modelled taking the effect of the earth’s rotation into account. It is found that the earth’s rotation leads to the appearance of an angle between the direction of the axis of the laser station telescope at the time a light pulse is emitted and the direction of the actual position of a spacecraft at the time this light is reflected from it.

Specifications, circuitry, and recommendations for the use of the OK6-13 automatic complex for testing instruments for the measurement of the parameters of fiber-optic transmission systems are presented. The complex supports tests of measurement instruments designed for operating at wavelengths of 0.85, 1.31, and 1.55 μm.

A new method of decreasing the errors in measurements of the coordinates of objects through quantization of signals in opto-electronic devices with multi-element radiation detectors is considered. Using certain relationships between the pixel pitch of the elements in the detector and the image width, it is shown that if the illuminance of the image of an object is distributed uniformly, the systematic component of this error is equal to zero and its random component depends on the scatter of the pixel pitch of the elements.
