Code of Federal Regulations Title 47. Telecommunication § 47.25.146 Licensing and operating provisions for NGSO FSS space stations

(1) Any applicable power flux-density levels in Article 21, Section V, Table 21–4 of the ITU Radio Regulations (incorporated by reference, § 25.108), except that in the 19.3–19.4 GHz and 19.6–19.7 GHz bands applicants must certify that they will comply with the ITU PFD limits governing NGSO FSS systems in the 17.7–19.3 GHz band;  and

(2) Any applicable equivalent power flux-density levels in Article 22, Section II, and Resolution 76 of the ITU Radio Regulations (both incorporated by reference, § 25.108).

(1) Communicate the ITU finding to the Commission;  and

(2) Submit the input data files used for the ITU validation software.

(1) The GSO satellite network has receive earth stations with earth station antenna maximum isotropic gain greater than or equal to 64 dBi;  G/T of 44 dB/K or higher;  and emission bandwidth of 250 MHz;  and

(2) The EPFD_down radiated by the NGSO satellite system into the GSO specific receive earth station, either within the U.S. for domestic service or any points outside the U.S. for international service, as calculated using the ITU software for examining compliance with EPFD limits exceeds—174.5 dB(W/(m²/40kHz)) for any percentage of time for NGSO systems with all satellites only operating at or below 2500 km altitude, or—202 dB(W/(m²/40kHz)) for any percentage of time for NGSO systems with any satellites operating above 2500 km altitude.
