In the last decade, satellite communications projects have emerged that use non-geostationary satellite orbits (non-GSO) making access to the shared radio frequency spectrum even more important. The International Telecommunication Union (ITU) forms the basis for the international regulatory framework and defines the obligations and requirements for interference-free operation of satellite systems using non-GSO. This presentation examines the mechanisms and outlines the changes implemented after the last World Radiocommunication Conference in 2019.
