AP8 – 108 – Notes to Table 10: NOTE 1 – The coordination distance, d (km), for fixed earth stations in the meteorological-satellite service vis-à-vis stations in the meteorological aids service assumes a radiosonde altitude of 20 km and is determined as a function of the physical horizon elevation angle h (degrees) for each azimuth, as follows: d 100 for h ≥ 11° d 582 1 (0.254 h )2 0.254 h for 0° < h < 11° d 582 for h ≤ 0° The minimum and maximum coordination distances are 100 km and 582 km, and correspond to physical horizon angles greater than 11° and less than 0°. (WRC-2000) NOTE 2 – For the coordination distance in the frequency band 5 091-5 150 MHz vis-à-vis stations in the aeronautical radionavigation service, see No. 5.444A. (WRC-15) APPENDIX 8 (REV.WRC-15) Method of calculation for determining if coordination is required between geostationary-satellite networks sharing the same frequency bands 2 Calculation of the apparent increase in equivalent noise temperature of the satellite link subject to an interfering emission MOD 2.4 Use of information furnished under Appendix 4 When an administration elects to use information furnished under Appendix 4 with the calculation procedures of § 2.2.1.1 and § 2.2.2.1 in order to formulate comments, the calculations need to be made for both sets of values of γ and T furnished. The greater of the two values of ΔT/T resulting from these calculations is the one to be used. (WRC-15)
