Observations of SO have been performed in optical and radio wave bands. The list for optical observations contains the following objects: - in low orbits - 28 SC from the list of International Laser Ranging Service, 98 SC and SD from the list of Ukrainian Network of Optical Stations; - in medium orbits - 9 satellites that are part of the Compass Navigation Satellite System or BeiDou-2 in Chinese transcription; 10 SO that are part of a series of Soviet and Russian satellites named "Cosmos"; 31 SO, included in the US satellite navigation system named Global Positioning System (GPS); - in geostationary orbits - 9 SC from two clusters of telecommunication geostationary satellites (TC GSS); 32 objects from the list of SD. The list for radio observations contains the following objects: - in low orbits - 36 spacecraft with radio beacons at a frequency of 430 MHz; - in geostationary orbits - 2 TC GSS belonging to the satellite operator Eutelsat (France). In the optical range using: - TV telescope of the MOBITEL complex, we carried out 1502 effective trackings of the SO in low orbits with a total duration of 1158 minutes during 31 nights, and a database of 17366 SO positions was obtained; - MEZON telescope of the MOBITEL complex, we carried out 101 effective trackings of the SO in medium orbits with a total duration of 281 minutes for 10 nights, and a database of 844 SO positions was obtained; - KT-50 telescope of the MOBITEL complex, we carried out 129 effective trackings of the SO in geostationary orbits with a total duration of 801 minutes for 18 nights, and a database of 2404 SO positions was obtained. In the radio range using: - Doppler station, we conducted observations in low orbits for 20 nights, 849 effective trackings with a total duration of 485 minutes, and a database of 7284 SO positions was obtained; - radio interferometric network of stations located in the cities of Mykolaiv, Rivne, Mukachevo, Kharkiv (Ukraine), Ventspils (Latvia), for synchronous reception of satellite TV signals, a database of coordinates of the TC GSS Eutelsat 13b was obtained for 155 days - 5 stations, 135 days - 4 stations, 68 days - 3 stations. With the help of the Doppler station and radio interferometric network of stations, 6 and 305 sets of orbital elements were obtained, respectively. The orbital elements were placed into the database of the RI "MAO" in two-line element set (TLE).
