Experimental Verification of Methods for Measuring and Predicting the Angular Motion of Orbital Stations and Their Practical Application to the Yamal GSS Attitude Control

On November 24, 2003, geostationary communications satellites Yamal-201 and Yamal-202 were inserted into orbit. The latter has been operating in orbit for more than 20 years. To a great extent, its successful operation results from the scientific and applied research conducted during the missions of Russian orbital stations, as well as some technological tests carried out at the Russian Segment of the International Space Station (ISS RS) which celebrated its 25th anniversary in orbit in 2023. The article presents the results of studies performed on board the orbital stations, which were then applied to the flight control of the Yamal-series satellites and facilitated their longevity in orbit.
