AP7 – 106 – Notes to Table 9b:1 A: analogue modulation; N: digital modulation. 2 On-axis gain of the receive earth station antenna. 3 Feeder links of non-geostationary satellite systems in the mobile-satellite service. 4 Geostationary-satellite systems. 5 Horizon antenna gain for the receive earth station (refer to § 3 of the main body of the Appendix). 6 Minimum elevation angle of operation in degrees (non-GSO or GSO). 7 Orbit of the space service in which the receiving earth station operates (GSO or non-GSO). 8 The thermal noise temperature of the receiving system at the terminal of the receiving antenna (under clear-sky conditions). Refer to § 2.1 of this Annex for missing values. 9 Horizon antenna gain is calculated using the procedure of Annex 5. Where no value of Gm is specified, a value of 42 dBi is to be used. 10 Horizon antenna gain is calculated using the procedure of Annex 5, except that the following antenna pattern may be used in place of that given in § 3 of Annex 3: G = 32 − 25 log φ for 1° ≤ φ < 48°; and G = −10 for 48° ≤ φ < 180° (refer to Annex 3 for definition of symbols). 11 Non-geostationary horizon antenna gain. Ge = Gmax (see § 2.2 of the main body of this Appendix) for G = 36 − 25 log (φ) > −6 (refer to Annex 3 for definition of symbols). 12 Non-geostationary horizon antenna gain. Ge = Gmax (see § 2.2 of the main body of this Appendix) for G = 32 − 25 log (φ) > −10 (refer to Annex 3 for definition of symbols).
