§ 25.140   Further requirements for license applications for geostationary space
stations in the Fixed-Satellite Service and the 17/24 GHz
Broadcasting-Satellite Service.

   (a) In addition to the information required by § 25.114, applicants for
   geostationary-orbit FSS space stations must provide an interference analysis
   to demonstrate the compatibility of their proposed system with respect to
   authorized space stations within 2 degrees of any proposed satellite point
   of communication. An applicant should provide details of its proposed radio
   frequency carriers which it believes should be taken into account in this
   analysis. At a minimum, the applicant must include, for each type of radio
   frequency carrier, the link noise budget, modulation parameters, and overall
   link performance analysis. (See Appendices B and C to Licensing of Space
   Stations  in the Domestic Fixed-Satellite Service, FCC 83-184, and the
   following public notices, copies of which are available in the Commission's
   EDOCS database: DA 03-3863 and DA 04-1708.)

   (b) Each applicant for a license for a 17/24 GHz Broadcasting-Satellite
   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 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 station in the 17/24 GHz BSS that complies with the
   technical rules in this part and that will be located at least four degrees
   from the proposed space station.

   (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 operating with another
   17/24 GHz BSS space station as close as four degrees away.

   (2) Satellite network operators located less than four degrees away from a
   space station to be operated pursuant to § 25.262(b) of this part must design
   their satellite networks to be capable of operating with that adjacent 17/24
   GHz BSS space station.

   (3) Satellite network operators using 17/24 GHz BSS space stations 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)-(g) [Reserved]
