Methodology for the calculation of the worst-case interference levels from a particular type of non-geostationary fixed-satellite service system using highly-elliptical orbits into geostationary fixed-satellite service satellite networks operating in the
The ITU Radiocommunication Assembly considering a) that many fixed-satellite service (FSS) frequency bands, including the 4/6 GHz bands, may be used for both geostationary (GSO) satellite networks and non-GSO satellite systems in accordance with the Radio Regulations (RR); b) in the 4/6 GHz bands non-GSO systems shall not cause unacceptable interference to GSO FSS networks in accordance with the provisions of RR No. 22.2; c) that administrations may need to calculate the worst-case interference level that is generated from a non-GSO system into any GSO network in the 4/6 GHz frequency bands; d) that the 4/6 GHz FSS frequency bands are heavily used by existing and planned GSO FSS networks.
