Federal Register / Vol. 86, No. 19 / Monday, February 1, 2021 / Proposed Rules
3 Each applicant for such new or modified feeder-link earth stations shall file with its application memoranda of coordination with each co-frequency licensee authorized to construct BSS
receive earth stations or an individually licensed FSS receive earth station within the coordination zone. Feeder link earth station applicants are not required to complete coordination with blanket-licensed receiving FSS earth stations in the 17.317.8 GHz band.
25.208
Amended
10. Amend 25.208 by removing and reserving paragraph w.
11. Amend 25.209 by revising the introductory text of paragraphs a1, 3 and 4, and 6, and b1 through 3 to read as follows:
25.209 Earth station antenna performance standards.
a
1 In the plane tangent to the GSO
arc, as defined in 25.103, for earth stations not operating in the conventional Ku-band, the 24.7525.25
GHz band, or the 27.530 GHz band:
3 In the plane tangent to the GSO
arc, for earth stations operating in the 24.7525.25 GHz or 27.530 GHz bands:
4 In the plane perpendicular to the GSO arc, as defined in 25.103, for earth stations not operating in the conventional Ku-band, the 24.7525.25
GHz band, or the 27.530 GHz band:
6 In the plane perpendicular to the GSO arc, for earth stations operating in the 24.7525.25 GHz or 27.530 GHz bands:
b

the 24.7525.25 GHz or 27.530 GHz bands:
2 In the plane perpendicular to the GSO arc, for earth stations not operating in the 24.7525.25 GHz or 27.530 GHz bands:
3 In the plane tangent to the GSO arc or in the plane perpendicular to the GSO arc, for earth stations operating in the 24.7525.25 GHz or 27.530 GHz bands:
12. Amend 25.210 by revising paragraph f to read as follows:
25.210 Technical requirements for space stations.
f All space stations in the FixedSatellite Service operating in any portion of the 36004200 MHz, 5091
5250 MHz, 58507025 MHz, 10.712.7
GHz, 12.7513.25 GHz, 13.7514.5 GHz, 15.4315.63 GHz, 17.317.8 GHz spaceto-Earth, 18.320.2 GHz, 24.7525.25
GHz, or 27.530.0 GHz bands, including feeder links for other space services, and in the Broadcasting-Satellite Service in the 17.317.8 GHz band space-toEarth, shall employ state-of-the-art full frequency reuse, either through the use of orthogonal polarizations within the same beam and/or the use of spatially independent beams. This requirement does not apply to telemetry, tracking, and command operation.
13. Amend 25.212 by revising paragraphs e and h to read as follows:
25.212 Narrowband analog transmissions and digital transmissions in the GSO FSS.
e An earth station may be routinely licensed for digital transmission in the conventional or extended Ka-bands if the input power spectral density into the antenna will not exceed 3.5 dBW/
MHz and the application includes certification pursuant to 25.132a1
PO 00000
Frm 00024
Fmt 4702
Sfmt 4702
of conformance with the antenna gain performance requirements in 25.209a and b.
h Applications for authority for fixed earth station operation in the conventional C-band, the extended Cband, the conventional Ku-band, the extended Ku-band, the conventional Kaband or the extended Ka-band that do not qualify for routine processing under relevant criteria in this 25.211 or 25.218 are subject to the requirements in 25.220.
14. Amend 25.218 by:
a. Revising paragraph a;
b. Adding a heading for paragraph b;
c. Revising paragraphs i and j.
The revisions and addition read as follows:
25.218 Off-axis EIRP density envelopes for FSS earth stations transmitting in certain frequency bands.
a Applicability. This section applies to applications for fixed and temporaryfixed FSS earth stations transmitting to geostationary space stations in the conventional C-band, extended C-band, conventional Ku-band, extended Kuband, conventional Ka-band, extended Ka-band, or 24.7525.25 GHz, and applications for ESIMs transmitting in the conventional C-band, conventional Ku-band, conventional Ka-band, except for applications proposing transmission of analog command signals at a band edge with bandwidths greater than 1
MHz or transmission of any other type of analog signal with bandwidths greater than 200 kHz.
b Routine Processing.
i Digital earth station operation in the conventional or extended Ka-band.
1 For co-polarized transmissions in the plane tangent to the GSO arc:
j Non-Qualifying Applications.
