ITU-R S.1555 FRENCH-2002 工作在6/4GHZ频带上的卫星固定业务中的近空间双循环和双线性偏振静止卫星网络之间的总干扰水平

The ITU Radiocommunication Assembly considering: a) that in the 6/4 GHz frequency bands both dual circular polarization (CP) and dual linear polarization (LP) are used by different operational geostationary-satellite fixed satellite service (FSS) networks, and this situation is likely to continue because of the established infrastructure in those networks; b) that such bands are heavily used resulting in the need for co-frequency and co-coverage networks to operate with relatively small orbital spacing; c) that the existing ITU-R Recommendations, as well as Appendix 8 to the Radio Regulations(RR), only address the single entry interference between adjacent satellite networks, taking the interfering signal in each polarization at a time; d) that it is important during coordination to be able to determine the aggregate effect of adjacent satellite interference arising from the simultaneous use of both orthogonal polarizations in each adjacent satellite network, whether the two networks use the same type of polarization (i.e. both CP or both LP) or whether they use different types of polarization (i.e. one using CP and the other using LP); e) that the magnitude of the two orthogonally polarized signals of the interfered with and/or the interfering networks could be equal or unequal.

The ITU Radiocommunication Assembly considering a) that emissions from space stations in the fixed-satellite service (FSS) operating in geostationary orbit (GSO) and sharing the same spectrum as the fixed service (FS) may produce interference in receiving stations of the FS; b) results obtained using a statistical approach compared to a worst-case analysis may lead to a more efficient use of the spectrum than results from criteria developed using worst-case analysis; c) that sharing methodologies should take into consideration the performance requirements and deployment characteristics of FS systems being used and planned for use in these frequency bands; d) that in spectrum where precipitation is the predominant fade mechanism it is desirable to have an interference evaluation tool using C/N, C/I and C/(N + I) statistics to determine impact on availability; e) that such an interference evaluation tool may have application in bands above about 17 GHz to assist administrations in performing sharing studies.
