§ 25.223   Alternative licensing rules for feeder-link earth stations in the
17/24 GHz BSS.

   (a) This section applies to license applications for earth stations
   that transmit to 17/24 GHz Broadcasting-Satellite Service space
   stations that are not eligible for routine processing under
   § 25.212(f).

   (b) All applications for earth station licenses in the 24.75-25.25 GHz
   portion of 17/24 GHz BSS shall be routinely processed if they meet the
   following requirements:

   (1) 17/24 GHz BSS earth station antenna off-axis EIRP spectral density
   for co-polarized signals shall not exceed the following values, within
   +-3DEG of the GSO arc, under clear sky conditions:
   32.5-25log(th) dBW/MHz for 2DEG <=th <=7DEG
   11.4           dBW/MHz for 7DEG <=th <=9.2DEG
   35.5-25log(th) dBW/MHz for 9.2DEG <=th <=48DEG
   3.5            dBW/MHz for 48DEG <=th <=180DEG

   Where th is the angle in degrees from the axis of the main lobe.

   (2) 17/24 GHz BSS earth station antenna off-axis EIRP spectral density
   for co-polarized signals shall not exceed the following values, for all
   directions other than within +-3DEG of the GSO arc, under clear sky
   conditions:
   35.5-25log(th) dBW/MHz for 2DEG <=th <=7DEG
   14.4           dBW/MHz for 7DEG <=th <=9.2DEG
   38.5-25log(th) dBW/MHz for 9.2DEG <=th <=48DEG
   6.5            dBW/MHz for 48DEG <=th <=180DEG

   Where th is the angle in degrees from the axis of the main lobe.

   (3) The values given in paragraphs (b) (1) and (2) of this section may
   be exceeded by 3 dB, for values of th >10DEG, provided that the total
   angular range over which this occurs does not exceed 20DEG when
   measured along both sides of the GSO arc.

   (4) 17/24 GHz BSS earth station antenna off-axis EIRP spectral density
   for cross-polarized signals shall not exceed the following values, in
   all directions greater than +3 relative to the GSO arc, under clear sky
   conditions:
   22.5-25log(th) dBW/MHz for 2DEG <=th <=7DEG
   1.4            dBW/MHz for 7DEG <=th <=9.2DEG

   Where is the angle in degrees from the axis of the main lobe.

   (c) Each earth station license applicant that proposes levels in excess
   of those defined in paragraph (b) of this section must certify that all
   potentially affected parties acknowledge and do not object to the use
   of the applicant's higher power densities. For proposed power density
   levels less than or equal to 3 dB in excess of the limits defined in
   paragraph (b) of this section, the potentially affected parties are
   operators of co-frequency U.S.-authorized 17/24 GHz BSS satellites at
   angular separations of up to +-6DEG from the proposed satellite points
   of communication; for power density levels greater than 3 dB and less
   than or equal to 6 dB in excess of the limits defined in paragraph (b)
   of this section, potentially affected parties are operators of
   co-frequency U.S.-authorized satellites up to +-10DEG from the proposed
   satellite points of communication. Power density levels greater than 6
   dB in excess of the limits defined in paragraph (b) of this section
   will not be permitted.

   (d) Licensees authorized pursuant to paragraph (c) of this section
   shall bear the burden of coordinating with any future applicants or
   licensees whose proposed compliant operations at 10 degrees or smaller
   orbital spacing, as defined by paragraph (b) of this section, is
   potentially or actually adversely affected by the operation of the
   non-compliant licensee. If no good faith agreement can be reached,
   however, the non-compliant licensee shall reduce its earth station EIRP
   spectral density levels to be compliant with those specified in
   paragraph (b) of this section.
