This standard compared with GB/T 13620-1992 main changes are as follows. --- Delete the original standard in all interference related to standard analog satellite communication earth station systems and analog microwave communication system, microwave station Accurate, interference calculation methods and attachment content; --- Revised earth station coordination area calculations, updated calculation of the coordination area required parameters, updated to allow the receiver input interference Flat way to judge; --- Improve the conditions for determining the coordination area, modify the coordination area two kinds of propagation mode determining methods and procedures; --- Interference precludes an increased coordination area two kinds of auxiliary propagation mode of calculation principles, the calculation method of the interference pre Exclude content has been simplified; --- Refine the method used to calculate the interference; --- Deleted Appendix A graphical method to determine the coordination area related content, retains the rain scatter-related climate-related content; --- Appendix B to calculate the diffraction loss content has been revised and updated. The standard revision process, the reference method for determining the ITU Radio Regulations 7 on satellite earth station coordination area Appendix Related Content, both of which are consistent with the basic principles and methods. Therefore, in accordance with the relevant national standard calculation performed equally adapted to carry out our satellite International coordination of earth stations and microwave stations. This standard Annex A, Annex B is normative appendix, Appendix C, Appendix D and Appendix E is an informative annex. This standard by the National Standardization Technical Committee on Radio Interference (SAC/TC79) and focal points. This standard was drafted. SRMC. The main drafters of this standard. Wang Xiaodong, Lijing Chun Cong Far East, Huang Biao, Pan Ji, Tseng Fan sound, Li Jianxin. This standard replaces the standards previously issued as follows. --- GB/T 13620-1992. Between satellite communication earth station and terrestrial microwave stations Identify and interference coordination area calculations1 ScopeThis standard is given in 1GHz ~ 40GHz range with frequency were shared satellite communication earth station (referred to as the body earth station) and ground Coordination microwave digital microwave radio relay station system (the body referred to microwave station) between the interference calculation methods. Determining the coordination area, pre-discharge interference In addition, practical interference calculation methods. This standard applies to coordinating earth station and microwave system between digital stations, interference calculations, the predicted results for the system design, installation Commissioning, completion and acceptance of basic data; also be used as the authorities in charge of radio interference coordination basis.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents. For undated reference documents, the latest versions apply to this standard.

Close coordination contours and surrounding area. 3.3 The area around the earth station, outside this area, sharing the same frequency band of terrestrial stations or produced by the interference level of the station, A specific percentage of time, not to exceed a permissible value. In the region between the frequencies associated earth stations and terrestrial stations should be coordinated. 3.4 Use to determine the relative coordination contour slightly loose assumptions based on some of the contours depicted. 3.5 From the center of the earth station antenna to connect to the highest point in all directions obstacle. 3.6 With auxiliary contours, simple and fast method to exclude interference. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 13620-2009_English be delivered?Answer: Upon your order, we will start to translate GB/T 13620-2009_English as soon as possible, and keep you informed of the progress.
