 More than 130,000 positions of 166 artificial space objects, which have a number in the US Department of Defense (NORAD) catalog, were obtained. The equatorial coordinates of all objects at the moment of observation were calculated. The standard errors of the coordinates have a value of no more than ±1.06". 8685 positions of 19 artificial Earth satellites in orbits with high eccentricity were obtained. The standard errors of the equatorial coordinates of these satellites have a value of no more than ±0.9". Most of these satellites do not have orbit elements in the NORAD catalog. An international network of 10 stations monitored the position of geostationary telecommunication satellites. The network has simultaneously observed three satellites named Eutelsat-13B, 13C, 13E since June 2021. The orbital elements of these satellites were calculated. A reference signal synthesizer at at frequency of 28.8 MHz was developed for the Doppler station receiver. The relative error of the frequency is 10-10, which corresponds to the standard error of the satellite radial velocity of ±4 cm/s. The standard error of time determination does not exceed ±30 ms. Regular observations of asteroids were made. Based on the results of data processing, a catalog of 5219 topocentric positions and apparent magnitudes for 130 asteroids was obtained. The positions were sent to the Minor Planet Center of the International Astronomical Union (IAU) and published on 12 pages of the IAU circular. The accuracy of our observations is at the international level. In 2021, 989 meteor phenomena were registered using optical telescopes. Archived data obtained in 2017-2020 has been processed. 15,184 meteor phenomena were detected out of 73,661 registered events. Simultaneous observations in two photometric bands were obtained for 38 meteors. Radio observations of meteors were carried out using two networks of stations. The two networks registered 626,695 meteors. The results were posted at the RMOB.
