§ 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.
