AP30A – 147 – ARTICLE 9A (REV.WRC-15) Plan for feeder links for the broadcasting-satellite service in the fixed-satellite service in the frequency bands 14.5-14.8 GHz and 17.3-18.1 GHz in Regions 1 and 3 MOD 9A.1 COLUMN HEADINGS OF THE PLAN Col. 1 Notifying administration symbol. Col. 2 Beam identification (Column 2, normally, contains the symbol designating the administration or the geographical area taken from Table B1 of the Preface to the International Frequency List, followed by the symbol designating the service area). Col. 3 Nominal orbital position, in degrees and hundredths of a degree from the Greenwich meridian (negative values indicate longitudes which are west of the Greenwich meridian; positive values indicate longitudes which are east of the Greenwich meridian). Col. 4 Nominal intersection of the beam axis with the Earth (boresight or aim point in the case of a non-elliptical beam), longitude and latitude, in degrees and hundredths of a degree. Col. 5 Space station receiving antenna characteristics (elliptical beams). This Column contains three numerical values corresponding to the major axis, the minor axis and the major axis orientation respectively of the elliptical cross-section half-power beam, in degrees and hundredths of a degree. Orientation of the ellipse determined as follows: in a plane normal to the beam axis, the direction of a major axis of the ellipse is specified as the angle measured anticlockwise from a line parallel to the equatorial plane to the major axis of the ellipse, to the nearest degree. Col. 6 Space station receiving antenna pattern code. The codes used for the antenna pattern of the receiving space station (feeder link) antenna are defined as follows: R13RSS Figure B (Curves A, B and C) and § 3.7.3 in Annex 3 R123FR Figure C and § 3.7.3 in Annex 3 MODRSS Figure B (Curves A′, B′ and C) and § 3.7.3 in Annex 3 (Recommendation ITU-R BO.1296) In cases where the “Space station receiving antenna pattern code” field is blank, the necessary antenna pattern data are provided by shaped beam data submitted by the administration. These data are stored in Column 7. A particular shaped beam is identified by the combination of Column 1, Column 7 and Column 14. In such cases the maximum cross-polar gain is given in Column 8, Cross-polar gain field.
