Catalogue of 1810 topocentric positions for 93 asteroids approaching the Earth was obtained. The standard error in determining the coordinates of asteroids is not more than ±0.3". Software named "Calculation of the final differences in the positions of small bodies of the solar system with ephemeris HORIZONS" was designed to calculate the differences (O - C) between the topocentric coordinates, which are obtained from the results of astrometric reduction of observations, and ephemeris coordinates at the time of observation using the HORIZONS system (JPL NASA , USA). Catalogue containing 391 topocentric position of 14 comets was obtained in the Gaia DR1 catalogue system. Mean difference (O - C) and their standard errors make up the value of (-0.03 ± 0.17)" in right ascension and (+0.01 ± 0.18)" in declination for comets of (10-17) mag. Catalogue containing 1647 topocentric positions of 39 main belt asteroids was obtained. The standard error of asteroid positions in the Gaia DR2 reference catalog system is ±0.13" in right ascension and ±0.15" in declination for asteroids (12-16.5) magnitude. Positions have been sent to the IAU MPC international database. Catalogue analysis testifies high accuracy in comparison with the best world achievements. During 2016-2018, objects of the international ground support project for the space mission OSIRIS-REx were included in the program of observations with the KT-50 telescope. A total of 195 positions were obtained for 6 objects. The received topocentric positions were sent to the IAU MPC international database. Software named "Calculation of motion vector and heliocentric orbital elements of meteoroids observed from two points" was designed to automate data processing. Catalogue of heliocentric orbital elements for 1055 meteoroids was obtained. The standard error of equatorial coordinates of a visible radiant is not more than 0.5° for a basis length of 11.6 km. The standard error of measuring the geocentric velocity of meteoroids is 0.5 km/s. The standard error of determining the heights of meteoroids is not more than 100 m. 30% of meteoroids in the catalogue have a mass of not more than 0.01 g.
