The ITU Radiocommunication Assembly considering a) that the World Radiocommunication Conference (Istanbul, 2000) (WRC-2000) adopted a combination of single-entry validation, single-entry operational and, for certain antenna sizes, single-entry additional operational equivalent power flux-density (downlink) (epfd↓) limits, contained in Article 22 of the Radio Regulations (RR), along with the aggregate limits in Resolution 76 (WRC-2000), which apply to non-geostationary fixed-satellite service (non-GSO FSS) systems, that protect GSO networks in parts of the frequency range 10.7-30 GHz; b) that compliance of a non-GSO FSS system with the single-entry operational epfd↓limits is not subject to verification by the Radiocommunication Bureau; c) that administrations with assignments to GSO FSS and/or broadcasting-satellite service (BSS) networks that have been brought into use, as well as administrations with assignments to non-GSO FSS systems that have been brought into use, require reliable means of ascertaining that non-GSO FSS systems are in compliance with the single-entry operational limits referred to in considering a); d) that epfd↓levels may have to be measured at operational GSO earth stations in order to determine if the operational limits are exceeded.
