§ 25.220 Non-routine transmit/receive earth station operations.
(a) The requirements in this section apply to applications for, and
operation of, earth stations transmitting in the conventional or
extended C-bands, the conventional or extended Ku-bands, the
24.75-25.25 GHz band, or the conventional Ka-band that do not qualify
for routine licensing under relevant criteria in § 25.138, § 25.211,
§ 25.212, § 25.218, § 25.221(a)(1) or (a)(3), § 25.222(a)(1) or (a)(3),
§ 25.226(a)(1) or (a)(3), or § 25.227(a)(1) or (a)(3).
(b) Applications filed pursuant to this section must include the
information required by § 25.115(g)(1).
(d)(1) The applicant must submit the certifications listed in
paragraphs (d)(1)(i) through (d)(1)(iv) of this section. The applicant
will be authorized to transmit only to the satellite systems included
in the coordination agreements referred to in the certification
required by paragraph (d)(1)(ii) of this section. The applicant will be
granted protection from receiving interference only with respect to the
satellite systems included in the coordination agreements referred to
in the certification required by paragraph (d)(1)(ii) of this section,
and only to the extent that protection from receiving interference is
afforded by those coordination agreements.
(ii) A statement from the satellite operator that it has coordinated
the operation of the subject non-conforming earth station accessing its
satellite(s), including its required downlink power density based on
the information contained in the application, with all adjacent
satellite networks within 6Â° of orbital separation from its
satellite(s), and the operations will operate in conformance with
existing coordination agreement for its satellite(s) with other
satellite systems, except as set forth in paragraph (d)(4) of this
(iii) A statement from the satellite operator that it will include the
subject non-conforming earth station operations in all future satellite
network coordinations, and
(iv) A statement from the earth station applicant certifying that it
will comply with all coordination agreements reached by the satellite
(2) Unless the non-routine uplink transmission levels are permitted
under a coordination agreement with the space station operator, or
unless coordination with the operator is not required pursuant to
§ 25.140(d)(3) or (d)(4), the operator of an earth station licensed
pursuant to this section must reduce its transmitted EIRP density to
levels at or within relevant routine limits:
(i) Toward the part of the geostationary orbit arc within one degree of
a subsequently launched, two-degree-compliant space station receiving
in the same uplink band at an orbital location within six degrees of
the earth station's target satellite, and
(ii) Toward a two-degree-compliant space station receiving in the same
uplink band at an orbital location more than six degrees away from the
target satellite if co-frequency reception by the space station is
adversely affected by the non-routine earth station transmission
(3) In the event that a coordination agreement discussed in paragraph
(d)(1)(ii) of this section is reached, but that coordination agreement
does not address protection from interference for the earth station,
that earth station will be protected from interference to the same
extent that an earth station that meets the requirements of § 25.209 of
this title would be protected from interference.
(4) Notwithstanding paragraph (d)(1)(ii) of this section, a party
applying for an earth station license pursuant to this section will not
be required to certify that its target satellite operator has reached a
coordination agreement with another satellite operator whose satellite
is within 6Â° of orbital separation from its satellite in cases where
the off-axis EIRP density level of the proposed earth station
operations will be less than or equal to the levels specified by the
applicable off-axis EIRP envelope set forth in § 25.218 of this chapter
in the direction of the part of the geostationary orbit arc within 1Â°
of the nominal orbit location of the adjacent satellite.
(g) Applicants filing applications for earth stations pursuant to this
section must provide the following information for the Commission's
(1) Detailed description of the service to be provided, including
frequency bands and satellites to be used. The applicant must identify
either the specific satellites with which it plans to operate, or the
eastern and western boundaries of the geostationary satellite orbit arc
it plans to coordinate.
(2) The diameter or equivalent diameter of the antenna.
(3) Proposed power and power density levels.
(4) Identification of any rule or rules for which a waiver is
