§ 25.117 Modification of station license.
(a) Except as provided for in § 25.118 (Modifications not requiring
prior authorization), no modification of a radio station governed by
this part which affects the parameters or terms and conditions of the
station authorization shall be made except upon application to and
grant of such application by the Commission.
(b) Both earth station and space station modification applications must
be filed electronically through the International Bureau Filing System
(IBFS) in accordance with the applicable provisions of part 1, subpart
Y of this chapter.
(c) Applications for modification of earth station authorizations must
be submitted on FCC Form 312, Main Form and Schedule B. Applications
for modification of space station authorizations must be submitted on
FCC Form 312, Main Form and Schedule S. Only those items that change
need to be specified, provided that the applicant certifies that the
remaining information has not changed.
(d)(1) Except as set forth in § 25.118(e), applications for
modifications of space station authorizations shall be filed in
accordance with § 25.114 and/or § 25.122 or § 25.123, as applicable, but
only those items of information listed in § 25.114 and/or § 25.122 or
§ 25.123 that change need to be submitted, provided the applicant
certifies that the remaining information has not changed.
(2) Applications for modifications of space station authorizations will
be granted except under the following circumstances:
(i) Granting the modification would make the applicant unqualified to
operate a space station under the Commission's rules.
(ii) Granting the modification request would not serve the public
interest, convenience, and necessity.
(iii) Except as set forth in paragraph (d)(2)(iv) of this section,
applications for modifications of GSO-like space station authorizations
granted pursuant to the procedure set forth in § 25.158, which seek to
relocate a GSO satellite or add a frequency band to the authorization,
will be placed in a queue pursuant to § 25.158 and considered only after
previously filed space station license applications or space station
modification applications have been considered.
(iv) Applications for modifications of space station authorizations to
increase the authorized bandwidth will not be considered in cases in
which the original space station authorization was granted pursuant to
the procedures set forth in § 25.157(e) or § 25.158(c)(4).
(v) Any 17/24 GHz BSS space station operator whose license is
conditioned to operate at less than the power level otherwise permitted
by § 25.208(c) and/or (w) of this part, and is conditioned to accept
interference from a neighboring 17/24 GHz BSS space station, may file a
modification application to remove those two conditions in the event
that the license for that neighboring space station is cancelled or
surrendered. In the event that two or more such modification
applications are filed, and those applications are mutually exclusive,
the modification applications will be considered on a first-come,
first-served basis pursuant to the procedure set forth in § 25.158 of
(3) In the event that a space station licensee provides notification of
a planned license modification pursuant to § 25.118(e), and the
Commission finds that the proposed modification does not meet the
requirements of § 25.118(e), the Commission will issue a public notice
announcing that the proposed license modification will be considered
pursuant to the procedure specified in paragraphs (d)(1) and (d)(2) of
(e) Any application for modification of authorization to extend a
required date of completion, as set forth in § 25.133 for earth station
authorizations or § 25.164 for space stations, or included as a
condition of any earth station or space station authorization, must
include a verified statement from the applicant:
(1) That states that the additional time is required due to
unforeseeable circumstances beyond the applicant's control, describes
these circumstances with specificity, and justifies the precise
extension period requested; or
(2) That states there are unique and overriding public interest
concerns that justify an extension, identifies these interests and
justifies a precise extension period (f) An application for
modification of a space station license to add an ancillary terrestrial
component to an eligible satellite network will be treated as a request
for a minor modification if the particulars of operations provided by
the applicant comply with the criteria specified in § 25.149.
Notwithstanding the treatment of such an application as a minor
modification, the Commission shall place any initial application for
the modification of a space station license to add an ancillary
terrestrial component on notice for public comment. Except as provided
for in § 25.149(f), no application for authority to add an ancillary
terrestrial component to an eligible satellite network shall be granted
until the applicant has demonstrated actual compliance with the
criteria specified in § 25.149(b).
(g) The licensee and grantees shall ensure compliance with the
Commission's radio frequency exposure requirements in § § 1.1307(b),
2.1091, and 2.1093 of this chapter, as appropriate. An Environmental
Assessment may be required if RF radiation from the proposed facilities
would, in combination with radiation from other sources, cause RF power
density or field strength in an accessible area to exceed the
applicable limits specified in § 1.1310 of this chapter. See
(h) Unless otherwise ordered by the Commission, an application for any
of the following kinds of modification of the operation of a GSO space
station will be deemed granted 35 days after the date of the public
notice that the application has been accepted for filing, provided no
objection is filed during the 30-day notice period and the application
does not propose a change that would be inconsistent with a Commission
rule or require modification of the BSS plan in Appendix 30 or the
associated feeder-link Plan in Appendix 30A of the ITU Radio
Regulations (both incorporated by reference, see § 25.108).
(1) Relocation of a DBS or GSO FSS space station by no more than 0.15Â°
from the initially authorized orbital location, provided the
application includes a signed certification that:
(i) The space station operator has assessed and limited the probability
of the satellite becoming a source of debris as a result of collisions
with large debris or other operational satellites at the new orbital
(ii) The proposed station-keeping volume of the satellite following
relocation will not overlap a station-keeping volume reasonably
expected to be occupied by any other satellite, including those
authorized by the Commission, applied for and pending before the
Commission, or otherwise the subject of an ITU filing and either in
orbit or progressing towards launch.
(2) Repositioning one or more antenna beams by no more than 0.3 angular
degrees from a line between the space station and the initially
authorized boresight location(s).
