Scope

The ITU Radiocommunication Assembly considering: a) that the band 6700-7075 MHz is allocated to the fixed-satellite service (FSS), in the space-to-Earth direction, on a primary basis, for the use by feeder links of non-geostationary satellite networks in the mobile-satellite service (MSS); b) that the band 6700-7075 MHz is also allocated to the FSS in the Earth-to-space direction, on a primary basis, and the band 6725-7025 MHz is subject to the Allotment Plan of Appendix 30B of the Radio Regulations (RR) for geostationary satellite networks; c) that, under No. S22.5A of the RR, the maximum aggregate power flux-density (pfd) produced within ±5℃ of the geostationary-satellite orbit (GSO) by a non-geostationary satellite system in the FSS shall not exceed -168 dB(W/m2) in any 4 kHz band; d) that Resolution 115 of the World Radiocommunication Conference (Geneva, 1995) (WRC-95) invites ITU-R to establish a methodology to determine the maximum aggregate power flux-density at the GSO from a non-geostationary satellite network; e) that non-geostationary satellite networks of the mobile-satellite service have orbital and transmission parameters available as specified in 5 A.3 vii) of Annex 1 to Resolution 46 (Rev.WRC-95).
