§ 25.118 Modifications not requiring prior authorization.
(a) Earth station modifications, notification required. Earth station
licensees may make the following modifications without prior Commission
authorization, provided they notify the Commission, using FCC Form 312
and Schedule B, within 30 days of the modification. The notification
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.
(1) Blanket-licensed earth station operators may add remote terminals
operating on a primary basis without prior authorization, provided they
have complied with all applicable frequency coordination procedures in
accordance with § 25.251.
(2) A licensee providing service on a private carrier basis may change
its operations to common carrier status without obtaining prior
Commission authorization. The licensee must notify the Commission using
FCC Form 312 within 30 days after the completed change to common
(3) An earth station operator may change a point of communication
without prior authorization, provided the operator does not repoint the
earth station's antenna beyond any coordinated range; and
(i) The change results from a space station relocation described in
paragraph (e) of this section, or
(ii) The new point of communication is a replacement GSO space station
within Â±0.15Â° of orbital longitude of the same location, with authority
to serve the U.S., and the change does not entail any increase in the
earth station's EIRP or EIRP density.
(4) An earth station licensee may additionally:
(i) Decrease antenna height; or
(ii) Increase or decrease the earth station's PFD contour, provided the
modification does not involve a change listed in paragraph (b)(2) of
(b) Earth station modifications, notification not required.
Notwithstanding paragraph (a) of this section:
(1) Equipment in an authorized earth station may be replaced without
prior authorization and without notifying the Commission if the new
equipment is electrically identical to the existing equipment.
(2) Licensees may make other changes to their authorized earth
stations, including the addition of new transceiver/antenna
combinations, without notifying the Commission, provided the
modification does not involve:
(i) An increase in EIRP or EIRP density (either main lobe or off-axis);
(ii) Additional operating frequencies;
(iii) A change in polarization;
(iv) An increase in antenna height;
(v) Antenna repointing beyond any coordinated range; or
(vi) A change from the originally authorized coordinates of more than 1
second of latitude or longitude for stations operating in frequency
bands shared with terrestrial systems or more than 10 seconds of
latitude or longitude for stations operating in frequency bands not
shared with terrestrial systems.
(e) Relocation of GSO space stations. A space station licensee may
relocate a GSO space station without prior authorization, but upon 30
days prior notice to the Commission and any potentially affected
licensed spectrum user, provided that the operator meets the following
requirements. The notification must be filed electronically on FCC Form
312 through the International Bureau Filing System (IBFS) in accordance
with the applicable provisions of part 1, subpart Y of this chapter:
(1) The space station will be relocated to a position within Â±0.15Â° of
an orbital location assigned to the same licensee.
(2) The licensee certifies that the space station will operate after
the relocation within the technical parameters authorized and
coordinated for the space station previously assigned to that location.
(3) The licensee certifies that it will comply with all the conditions
of its license for operation at the changed location.
(4) The licensee certifies that it will limit operations of the space
station to tracking, telemetry, and command functions during the
relocation and satellite drift transition period.
(5) The licensee certifies that:
(i) It 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 location; and
(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.
(6) The licensee certifies that the relocation will not result in a
lapse of service for any current customer.
(7) If the space station to be relocated is a DBS space station, the
licensee certifies that there will be no increase in interference due
to the operations of the relocated space station that would require the
Commission to submit a proposed modification to the ITU Appendix 30
Broadcasting-Satellite Service Plan and/or the Appendix 30A feeder-link
Plan (both incorporated by reference, see § 25.108) to the ITU
Radiocommunication Bureau. A DBS licensee that meets this certification
requirement is not subject to the requirements in paragraph (e)(2) of
(8) If the space station to be relocated is a DBS space station, the
licensee certifies that it will meet the geographic service
requirements in § 25.148(c) after the relocation.
(f) Repositioning of NGSO space stations. A licensee may reposition
NGSO space stations within an authorized orbital plane without prior
Commission approval, provided the licensee notifies the Commission of
the repositioning 10 days in advance by electronic filing on Form 312
in the International Bureau Filing System. The notification must
specify all changes in previously authorized parameters and must
certify the following:
(1) The licensee will continue to comply with the conditions of the
space station license and all applicable Commission rules, including
geographic coverage requirements, after the repositioning;
(2) The repositioning will not increase risk of harmful interference to
other systems not permitted by coordination agreements;
(3) The licensee will not request increased interference protection
because of the repositioning;
(4) The licensee will monitor collision risk during the maneuver and
take any necessary evasive measures.
(5) Any change of orbital altitude entailed by the repositioning will
not exceed 10 kilometers in extent or 30 days in duration and the
licensee has notified, or will notify, the operator(s) of any satellite
within 20 kilometers of the interim orbit at least 10 days before
commencing the repositioning maneuver.
