GB/T 13620-2009 is the English-translated version of 卫星通信地球站与地面微波站之间协调区的确定和干扰计算方法.
GB/T 13620-2009 is the Chinese standard "Determination of coordination area and predication methods of interference between satellite communication earth station and terrestrial microwave station".
Its scope clause reads: This 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. Its clauses include terms and definitions.

1 Scope
This 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.

3 Terms and Definitions
3.1
On a given azimuth from the earth stood up and count the distance, this distance is located outside of a common ground station of the same band with the station
Arising out of or subject to interference level, within a specified percentage of the time, should not exceed a permissible value.
3.2
Connecting curve earth station coordination distance end position and the formation of parties. 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.
