Abstract: FIELD: radio navigation.SUBSTANCE: invention relates to radio navigation and can be used to determine the relative distances to an object, including a mobile one, from stations of a ground system. According to the present method, at each station, a radio signal is transmitted synchronously in the form of two groups, each of which is formed from three components, which are harmonic oscillations with equal amplitudes and with given frequencies. One of the three harmonic vibrations of the first group is common with one of the three harmonic vibrations of the second group. At the facility, a set of radio signals transmitted by the stations is received quadrature. Digital quadrature components (CQC) corresponding to the received set of radio signals are formed one by one with a given sampling frequency and the number of clock cycles in a cycle. Three pairs of digital quadrature components (QCs) corresponding to the components of the transmitted radio signals are extracted from the generated CQCs and formed for each group. Then, by accumulating QC for a given number of clock cycles, three pairs of digital quadrature components corresponding to the indicated groups are formed. Using the digital quadrature components obtained in this way, the parameters given in the method are formed and, using them, for each k-th group of stations, time delays relative to the k-th group of a given station are determined. Based on the time delays and when the conditions specified in the method are met, the relative distances to the phase center (FC) of the antenna of the object from the FC antennas of the stations in the zone of unambiguous determination of the relative distances are uniquely determined, regardless of the distance of the moving object to the stations. The method makes it possible to exclude the influence of radio signals reflected, for example, from the ground, and random phases of the local oscillators of the transmitters and the receiver. No common synchronization is required between the object and the set of transmitted stations.EFFECT: increased accuracy and increased zone of unambiguous determination of relative ranges.1 cl

Abstract: FIELD: coating.SUBSTANCE: group of inventions relates to a method for chemical treatment and electroplating of parts and to an automatic chamber for chemical treatment and electroplating of parts by said method. In the method, the parts are loaded into baths placed in a sealed chamber, and process operations are executed when the parts are submerged in the corresponding solution bubbled with an inert gas. Prior to all operations, the air is displaced from the chamber by the inert gas, ensuring simultaneous full binding of the atmospheric oxygen residues in the chamber when a heated solution of alkali metal sulphites is supplied by rain, and the deoxygenated inert gas is circulated by being pumped from said chamber and returned to the baths for bubbling, wherein the pressure in the chamber is maintained at the level of pressure outside of the chamber by replenishing the leakage of inert gas from the chamber. All operations are executed in the baths without transferring parts while consecutively replacing the solutions by supplying into the baths and separately pouring out into deep cleaning and adjustment equipment using liquid switching units based on electromagnetic valves controlled by a controller. The electroplating solutions are supplied into the baths fully purified from sludge, including submicronic sludge, adjusted by composition, density, acidity coefficient, and temperature.EFFECT: group of inventions is aimed at enhancing the quality and expanding the functional capabilities of chemical treatment and electroplating of parts, and provides corrosion-resistant coatings on the surface of parts with a reduction in the metal consumption and size of the equipment.4 cl, 5 dwg
