适用范围

The ITU Radiocommunication Assembly considering a) that the World Radiocommunication Conference (Istanbul, 2000) (WRC-2000) adopted, in Article 22 of the Radio Regulations (RR), limits to the downlink equivalent power flux-density (epfd↓) radiated by non-geostationary (GSO) fixed-satellite service (FSS) systems in certain frequency bands, to protect GSO FSS and broadcasting-satellite service (BSS) networks operating in the same frequency bands; b) that RR Article 22 includes single-entry validation limits to the epfd↓in RR Tables 22-1A to 22-1D, single-entry operational limits to the epfd↓in RR Tables 22-4A, 22-4B and 22-4C, and single-entry additional operational limits to the epfd↓into antennas of certain sizes in RR Table 22-4A1, which apply to non-GSO FSS systems for the protection of GSO FSS networks; c) that compliance of a proposed non-GSO FSS system with the single-entry validation limits will be evaluated by the Radiocommunication Bureau (BR), under RR Nos. 9.35 and 11.31, based on masks of pfd provided by the non-GSO FSS operator, using software defined in Recommendation ITU-R S.1503; c) that compliance of a proposed non-GSO FSS system with the single-entry validation limits will be evaluated by the Radiocommunication Bureau (BR), under RR Nos. 9.35 and 11.31, based on masks of pfd provided by the non-GSO FSS operator, using software defined in Recommendation ITU-R S.1503; d) that compliance of a proposed non-GSO FSS system with the single-entry operational limits to the epfd↓and, for certain antenna sizes, single-entry additional operational limits to the epfd↓is subject to verification by administrations; e) that RR Appendix 4, as modified by WRC-2000, requires an administration responsible for a non-GSO FSS system to ensure that the single-entry additional operational limits to the epfd↓are met.
