The purpose of this Recommendation is to establish the technical basis for global circulation of IMT satelliteterminals on the basis that these terminals are not causing harmful interference to other radio communicationsystems in any country where they circulate:by conforming to IMT-2000 and IMT-Advanced satellite radio-interface specifications; andby complying with unwanted emission limits for IMT-2000 and IMT-Advanced satellite radiointerfaces.

ITU-R TF.1153-4-2015 使用伪随机噪声码的双向卫星时间和频率传送的运行使用

TWSTFT has been recognized as the most precise and accurate means for remote clock comparisons and is thus widely used in the time and frequency community, including institutions and organizations affiliated with telecommunication administrations. In view of the progress in performance of the atomic clocks compared via TWSTFT it was found necessary to calculate corrections applied to the measurement results with a higher accuracy than considered necessary in previous editions. As the Earth is not perfectly spherical, it is considered as an ellipsoid at first approximation. For a given location, there are a single longitude and two latitudes: the geocentric latitude and the geodetic latitude. The current version takes proper care of this in the calculation of the Sagnac correction.

ITU-R P.679-4-2015 设计卫星广播系统所需的传播数据

Broadcasting by satellite leads to propagation considerations that are not entirely comparable withthose occurring in the fixed-satellite service. Attenuation data for the space-to-Earth direction areneeded in the form of statistical averages and/or contour maps of attenuation and depolarization forlarge areas. Specific coordination problems may arise at the margin of the service area betweensatellite broadcasting systems and terrestrial or other space services. General methods for predictionof Earth-space path propagation effects are presented in Recommendation ITU-R P.618. Additionalinformation specific to satellite broadcasting system planning is treated in this Annex. It should benoted that feeder links are considered to be part of fixed-satellite services, not the broadcastingservices
