10、everal ITU-R Recommendations addressing various aspects of frequency sharing between the fixed service (FS) and mobile-satellite service (MSS). It also categorizes these Recommendations in order to facilitate their application. The ITU Radiocommunication Assembly, considering a) that various portion

11、s of the 1-3 GHz frequency range are allocated to the fixed service (FS) and that this service continues to be extensively used by many administrations; b) that recent world radiocommunication conferences have made new allocations to the MSS in the 1-3 GHz range; c) that most of the new allocations

12、for the MSS in the 1-3 GHz range have been established in frequency bands that were already allocated to the fixed service; d) that numerous ITU-R Recommendations have been established regarding various aspects of frequency sharing between the fixed service and MSS, and that an analytical index whic

13、h identifies and categorizes these Recommendations will facilitate their application; e) that in accordance with the Radio Regulations (RR) Article 9 and Appendix 7, a coordination area is determined to identify fixed service stations which could affect or be affected by the operation of mobile eart

14、h stations (MESs), and analyses, if required, may be needed in the course of coordination to further define the potential for interference and identify design and operating constraints that may be needed to resolve any difficulties; f) that in order to prevent interference between MSS (space-to-Eart

15、h) transmissions and receiving fixed service stations, the RR specify thresholds of pfd and fractional degradation in performance as well as a system-specific methodology (RR Appendix 5) to determine whether coordination is required, and analyses may be needed in the course of coordination to define

16、 the potential for interference and design and operating constraints that may be needed to resolve any difficulties, recognizing a) that the specific factors and methodologies applied in the course of coordination are subject to agreement of the parties concerned, and that the relevant ITU-R Recomme
