§ 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 ±3° of
the GSO arc, under clear sky conditions:
32.5-25log(θ) dBW/MHz for 2° ≤θ ≤7°
11.4 dBW/MHz for 7° ≤θ ≤9.2°
35.5-25log(θ) dBW/MHz for 9.2° ≤θ ≤48°
3.5 dBW/MHz for 48° ≤θ ≤180°
Where θ 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 ±3° of the GSO arc, under clear sky conditions:
35.5-25log(θ) dBW/MHz for 2° ≤θ ≤7°
14.4 dBW/MHz for 7° ≤θ ≤9.2°
38.5-25log(θ) dBW/MHz for 9.2° ≤θ ≤48°
6.5 dBW/MHz for 48° ≤θ ≤180°
Where θ 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 θ >10°, provided that the total angular
range over which this occurs does not exceed 20° 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(θ) dBW/MHz for 2° ≤θ ≤7°
1.4 dBW/MHz for 7° ≤θ ≤9.2°
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
±6° 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 ±10°
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.
