Also we plan to investigate the interaction of the lithosphere structure with anomalous deformations of the surface according to GNSS observations. We will performe astrometric monitoring of brown dwarfs that are optically, spectroscopically, or, according to the GAIA Space Telescope, by dual systems. Detection of satellites, determination of orbital parameters and dynamic masses in binary systems.Telescopes: VLT / FORS2, GTC / OSIRIS. Extending the photographic overview of the FON program to weaker stars, to the southern zones of the sky (more than 60% of the total sky area), and supplementing astrometric catalogs with photometric U and V values. Development of a technique for observing stars with asteroids. Observation processing, accuracy of finite parameters (passage time, position, asteroid size). Creating catalogs of coordinates and stellar magnitudes of small bodies of the solar system based on the processing of digitized photographic plates. Using the Gaia DR2 catalog and UkrVO digital archives to maximize accuracy and increase the number of original positions of individual asteroids. popup.description2 The work of the GNSS stations of the MAO of the NAS of Ukrainein cluded in the so-called Ukrainian permanent GNSS network was supported, which extends the implementation of the International Terrestrial Reference System (ITRF) to the territory of Ukraine and is the basis for the formation of the national coordinate system. The MAO of the NAS of Ukraine continued to be the Operations Center for permanent GNSS stations of other Ukrainian operators, regular collection and analysis of observation results were carried out. The mutual coordinates of the observation stations and reference points at the Crimean geodynamic test site were determined. Laser ranging observations of artificial Earth satellites (EAS) were carried out. The results obtained were sent to international databases. These data were used in the creation of a new implementation of ITRF. The laser station equipment and software were modernized, which allowed to increase the amount of information received and increase the accuracy of one measurement to 3 cm. A method for constructing telescope pointing errors using the machine learning method was developed. Software was developed for processings cans of large-format astroplates. Based on the results of plate scanning, a catalog of equatorial coordinates and V-magnitudes for 2,673,686 stars and galaxies was created. 1,560 plates were processed, and the FON-Dushanbe catalog of 29,994,052 objects was created. Astrometric studies of the DENIS J063001.4-184014AB supercool dwarf system were conducted, and the parameters of the binary system were refined. The masses and rotation periods of the supercool dwarf system 2M0805+48 and 2M1059−21 were determined. The characteristics of the differential atmospheric tremor were calculated based on observation data from the FORS2 camera on the VLT telescope. A network of points was created for observing events of the covering of stars by objects of the Solar System. 20 successful observations of such events were made.
