18、ary basis; b) that the frequency band 5 030-5 150 MHz is to be used for the operation of the international standard microwave landing system for precision approach and landing. The frequency band 5 091-5 150 MHz is also used in the FSS for feeder links for non-geostationary mobile-satellite service

19、systems. The requirements of the international standard microwave landing system shall take precedence over other uses of the band 5 030-5 091 MHz in accordance with No. 5.444 of the Radio Regulations, recommends 1 that the technical and operational requirements for stations of AM(R)S limited to sur

NOTE Due to the fact that other l

25、quired. The pfd defined in this section is based on ensuring that the increase in noise temperature of the FSS satellite due to operation in the frequency band 5 091-5 150 MHz of the AM(R)S (i.e. (Ts/Ts)AM(R)S) does not exceed the greater of the following two values: 1) 2% 2) 5% (Ts/Ts)ARNS where: (

26、Ts/Ts)ARNS: is the increase in noise temperature due to the ARNS in the same band. Three examples of this calculation are provided below. The first assumes that the (Ts/Ts)ARNS is 3%. The second assumes that no ARNS is present in the band. The third assumes that (Ts/Ts)ARNS is 3%. The methodology as

Example 1: (Ts/Ts)ARNS = 3% In this case, 5% (Ts/Ts)ARNS equals 2%, hence, (Ts/Ts)AM(R) S = 2%, i.e. 17 dB. Assuming the Table 1 characteristics for the FSS, the maximum aggregate interfer

Example 2: (Ts/Ts)ARNS = 0 In this case, 5% (T

ITU-R M.1827-1 Hence: M H z )23.1/d B ( W3.153dB13 K TBI R e cA g g Therefore at the satellite receiver antenna input the maximum pfd level produced by one AMRS transmitter is: )M H z23.1m/(d B W77.1416.3597.2319.243.1534l o g10)250(l o g102210 PF e e dR e cA g gM a x LLGrIp f dExample 3: (Ts/Ts)ARNS 3% In this case, 5% (Ts/Ts)ARNS is smaller than 2%, Hence, (Ts/Ts)AM(R)S = 2%, i.e. 17 dB, as in Example 1, and the same pfdMax value is obtained as in Example 1.
