§ 25.140   Further requirements for license applications for GSO space station
operation in the FSS and the 17/24 GHz BSS.

   (a)(1) In addition to the information required by § 25.114, an applicant
   for GSO FSS space station operation involving transmission of analog
   video signals must certify that the proposed analog video operation has
   been coordinated with operators of authorized co-frequency space
   stations within six degrees of the requested orbital location.

   (2) In addition to the information required by § 25.114, an applicant
   for GSO FSS space station operation at an orbital location less than
   two degrees from the assigned location of an authorized co-frequency
   GSO space station must either certify that the proposed operation has
   been coordinated with the operator of the co-frequency space station or

   (3) In addition to the information required by § 25.114, an applicant
   for a GSO FSS space station must provide the following for operation
   other than analog video operation:

   (i) With respect to proposed operation in the conventional or extended
   C-bands, a certification that downlink EIRP density will not exceed 3
   dBW/4kHz for digital transmissions or 8 dBW/4kHz for analog
   transmissions and that associated uplink operation will not exceed
   applicable EIRP density envelopes in § 25.218 or § 25.221(a)(1) unless
   the non-routine uplink and/or downlink operation is coordinated with
   operators of authorized co-frequency space stations at assigned
   locations within six degrees of the orbital location of the proposed
   space station and except as provided in paragraph (d) of this section.

   (ii) With respect to proposed operation in the conventional or extended

   the orbital location of the proposed space station and except as
   provided in paragraph (d) of this section.

   (iii) With respect to proposed operation in the conventional Ka-band, a
   certification that the proposed space station will not generate power
   flux-density at the Earth's surface in excess of −118 dBW/m2/MHz and
   that associated uplink operation will not exceed applicable EIRP
   density envelopes in § 25.138(a) unless the non-routine uplink and/or

   GHz (Earth-to-space) bands, a statement that the proposed operation
   will take into account the applicable requirements of Appendix 30B of
   the ITU Radio Regulations (incorporated by reference, see § 25.108) and
   a demonstration that it is compatible with other U.S. ITU filings under
   Appendix 30B.

   Service space station must provide the following information, in
   addition to that required by § 25.114:

   (1)-(2) [Reserved]

   (3) Except as described in paragraph (b)(5) of this section, an
   applicant for a license to operate a 17/24 GHz BSS space station that
   will be located precisely at one of the 17/24 GHz BSS orbital locations
   specified in Appendix F of the Report and Order adopted May 2, 2007, IB
   Docket No. 06-123, FCC 07-76, must certify that the downlink power flux
   density on the Earth's surface will not exceed the values specified in
   § 25.208(w), and that the associated feeder-link earth station
   transmissions will not exceed the EIRP density limits in § 25.223(c)
   unless the non-conforming uplink operation is coordinated with other
   affected 17/24 GHz BSS systems in accordance with § 25.223(c).

   (4) Except as described in paragraph (b)(5) of this section, an
   applicant for a license to operate a 17/24 GHz BSS space station that
   will not be located precisely at one of the nominal 17/24 GHz BSS
   orbital locations specified in Appendix F of the Report and Order
   adopted May 2, 2007, IB Docket No. 06-123, FCC 07-76, must make one of
   the following showings:

   (i) In cases where there is no previously licensed or proposed space
   station to be located closer than four degrees from the applicant's
   space station, and the applicant seeks to operate pursuant to
   § 25.262(b) of this part, the applicant must provide an interference
   analysis of the kind described in paragraph (a) of this section, except
   that the applicant must demonstrate the compatibility of its proposed
   network with any current or future authorized space stations in the
   17/24 GHz BSS that are operating in compliance with the technical rules
   of this part and that will be located at least four degrees from the
   applicant's proposed space station;

   (ii) In cases where there is a previously licensed or proposed 17/24
   GHz BSS space station to be located within four degrees of the
   applicant's proposed space station, the applicant must provide an
   interference analysis of the kind described in paragraph (a) of this
   section, except that the applicant must demonstrate that its proposed
   network will not cause more interference to the adjacent 17/24 GHz BSS
   satellite networks operating in compliance with the technical
   requirements of this part, than if the applicant were located at the
   precise Appendix F orbital location from which it seeks to offset;

   (iii) In cases where there is no previously licensed or proposed 17/24
   GHz BSS space station to be located within four degrees of the
   applicant's proposed space station, and the applicant does not seek to
   operate pursuant to § 25.262(b) of this part, the applicant must provide
   an interference analysis of the kind described in paragraph (a) of this
   section, except that the applicant must demonstrate that its proposed
   operations will not cause more interference to any current or future
   17/24 GHz BSS satellite networks operating in compliance with the
   technical requirements of this part, than if the applicant were located
   at the precise Appendix F orbital location from which it seeks to
   offset.

   (5) An applicant for a license to operate a 17/24 GHz BSS space
   station, in cases where there is a previously licensed or proposed
   space station operating pursuant to § 25.262(b) of this part located
   within four degrees of the applicant's proposed 17/24 GHz BSS space
   station, must provide an interference analysis of the kind described in
   paragraph (a) of this section, except that the applicant must
   demonstrate that its proposed operations will not cause more
   interference to the adjacent 17/24 GHz BSS satellite network than if
   the adjacent space station were located four degrees from the
   applicant's space station.

   (6) In addition to the requirements of paragraphs (b)(3), (b)(4), and
   (b)(5) of this section, the link budget for any satellite in the 17/24
   GHz BSS must take into account longitudinal stationkeeping tolerances
   and, where appropriate, any existing orbital location offsets from the
   17/24 GHz BSS orbital locations of the adjacent prior-authorized 17/24
   GHz BSS space stations. In addition, any 17/24 GHz BSS satellite
   applicant that has reached a coordination agreement with an operator of
   another 17/24 GHz BSS satellite to allow that operator to exceed the
   pfd levels specified in the rules for this service, must use those
   higher pfd levels for the purposes of this showing.

   (c) Operators of satellite networks using 17/24 GHz BSS space stations
   must design their satellite networks to be capable of operating with
   another 17/24 GHz BSS space station as follows:

   (1) Except as described in paragraphs (b)(4)(ii) and (b)(4)(iii) of
   this section, all satellite network operators using 17/24 GHz BSS space
   stations must design their satellite networks to be capable of

   located at an orbital location other than those specified in Appendix F
   of the Report and Order adopted May 2, 2007, IB Docket No. 06-123, FCC
   07-76, and that are not operating pursuant to § 25.262(b) of this part,
   must design their satellite networks to be capable of operating with
   another 17/24 GHz BSS space station closer than four degrees away, as a
   result of the operator's offset position.

   (d) An operator of a GSO FSS space station in the conventional or
   extended C-bands, conventional or extended Ku-bands, or conventional
   Ka-band may notify the Commission of its non-routine transmission
   levels and be relieved of the obligation to coordinate such levels with
   later applicants and petitioners.

   (1) The letter notification must include the downlink off-axis EIRP
   density levels or power flux density levels and/or uplink off-axis EIRP
   density levels, specified per frequency range and space station antenna
   beam, that exceed the relevant routine limits set forth in paragraphs
   (a)(3)(i) through (iii) of this section and § 25.138(a), § 25.218,

   § 25.151(a)(11).

   (3) Non-routine transmissions notified pursuant to this paragraph (d)
   need not be coordinated with operators of authorized co-frequency space
   stations that filed their complete applications or petitions after the
   date of filing of the notification with the Commission. Such later
   applicants and petitioners must accept any additional interference
   caused by the notified non-routine transmissions.

   (4) An operator of a replacement space station, as defined in
   § 25.165(e), may operate with non-routine transmission levels to the
   extent permitted under paragraph (d)(3) of this section for the
   replaced space station.
