(space-to-Earth), 11.7-12.2 GHz (space-to-Earth) bands and transmitting in
the 14.0-14.5 GHz (Earth-to-space) band, operating with Geostationary Orbit
(GSO) Satellites in the Fixed-Satellite Service.

   (a) The following ongoing requirements govern all ESV licensees and
   operations in the 10.95-11.2 GHz (space-to-Earth), 11.45-11.7 GHz
   (space-to-Earth), 11.7-12.2 GHz (space-to-Earth) and 14.0-14.5 GHz
   (Earth-to-space) bands transmitting to GSO satellites in the
   Fixed-Satellite Service.ESV licensees must comply with the requirements
   in paragraph (a)(1), (a)(2) or (a)(3) of this section and all of the
   requirements set forth in paragraphs (a)(4) through (a)(8) of this
   section. Paragraph (b) of this section identifies items that must be
   included in the application for ESV operations to demonstrate that
   these ongoing requirements will be met.

   (1) The following requirements shall apply to an ESV that uses
   transmitters with off-axis effective isotropically radiated power
   (EIRP) spectral-densities lower than or equal to the levels in
   paragraph (a)(1)(i)(A) of this section. An ESV, or ESV system,
   operating under this section shall provide a detailed demonstration as
   described in paragraph (b)(1) of this section. The ESV transmitter also
   must comply with the antenna pointing and cessation of emission
   requirements in paragraphs (a)(1)(ii) and (a)(1)(iii) of this section.

   (i) An ESV system shall not exceed the off-axis EIRP spectral-density
   limits and conditions defined in paragraphs (a)(1)(i)(A) through
   (a)(1)(i)(D) of this section.

   (A) The off-axis EIRP spectral-density emitted from the ESV, in the
   plane of the GSO as it appears at the particular earth station
   location, shall not exceed the following values:
   15 -10log(N) -25logth dBW/4 kHz for 1.5DEG <=th <=7DEG
   -6 -10log(N)          dBW/4 kHz for 7DEG 7.0DEG. For th greater
   than 7.0DEG, the envelope may be exceeded by no more than 10% of the
   sidelobes, provided no individual sidelobe exceeds the envelope given
   above by more than 3 dB.

   (B) In all directions other than along the GSO, the off-axis EIRP
   spectral-density for co-polarized signals emitted from the ESV shall
   not exceed the following values:
   18 -10log(N) -25logth dBW/4 kHz for 3.0DEG <=th <=48DEG
   -24 -10log(N)         dBW/4 kHz for 48DEG 11.45-11.7 GHz
   (space-to-Earth) frequency bands ESVs shall not claim protection from
   interference from any authorized terrestrial stations to which
   frequencies are either already assigned, or may be assigned in the
   future.

   (b) Applications for ESV operation in the 14.0-14.5 GHz
   (Earth-to-space) band to GSO satellites in the Fixed-Satellite Service
   must include, in addition to the particulars of operation identified on
   Form 312, and associated Schedule B, the applicable technical
   demonstrations in paragraphs (b)(1) or (2) of this section and the
   documentation identified in paragraphs (b)(3) through (5) of this
   section.

   (1) An ESV applicant proposing to implement a transmitter under
   paragraph (a)(1) of this section must demonstrate that the transmitter
   meets the off-axis EIRP spectral-density limits contained in paragraph
   (a)(1)(i) of this section. To provide this demonstration, the
   application shall include the tables described in paragraph (b)(1)(i)
   of this section or the certification described in paragraph (b)(1)(ii)
   of this section. The ESV applicant also must provide the value N
   described in paragraph (a)(1)(i)(A) of this section. An ESV applicant
   proposing to implement a transmitter under paragraph (a)(1)(ii)(A) of
   this section must provide the certifications identified in paragraph
   (b)(1)(iii) of this section. An ESV applicant proposing to implement a
   transmitter under paragraph (a)(1)(ii)(B) of this section must provide
   the demonstrations identified in paragraph (b)(1)(iv) of this section.

   (i) Any ESV applicant filing an application pursuant to paragraph
   (a)(1) of this section must file three tables showing the off-axis EIRP
   level of the proposed earth station antenna in the direction of the
   plane of the GSO; the co-polarized EIRP in the elevation plane, that
   is, the plane perpendicular to the plane of the GSO; and cross
   polarized EIRP. In each table, the EIRP level must be provided at
   increments of 0.1DEG for angles between 0DEG and 10DEG off-axis, and at
   increments of 5DEG for angles between 10DEG and 180DEG off-axis.

   (A) For purposes of the off-axis EIRP table in the plane of the GSO,
   the off-axis angle is the angle in degrees from the line connecting the
   focal point of the antenna to the orbital location of the target
   satellite, and the plane of the GSO is determined by the focal point of
   the antenna and the line tangent to the arc of the GSO at the orbital
   position of the target satellite.

   (B) For purposes of the off-axis co-polarized EIRP table in the
   elevation plane, the off-axis angle is the angle in degrees from the
   line connecting the focal point of the antenna to the orbital location
   of the target satellite, and the elevation plane is defined as the
   plane perpendicular to the plane of the GSO defined in paragraph
   (b)(1)(i)(A) of this section.

   (C) For purposes of the cross-polarized EIRP table, the off-axis angle
   is the angle in degrees from the line connecting the focal point of the
   antenna to the orbital location of the target satellite and the plane
   of the GSO as defined in paragraph (b)(1)(i)(A) of this section will be
   used.

   (ii) A certification, in Schedule B, that the ESV antenna conforms to
   the gain pattern criteria of §  25.209(a) and (b), that, combined with
   the maximum input power density calculated from the EIRP density less
   the antenna gain, which is entered in Schedule B, demonstrates that the
   off-axis EIRP spectral density envelope set forth in paragraphs
   (a)(1)(i)(A) through (C) of this section will be met under the
   assumption that the antenna is pointed at the target satellite. If an
   antenna proposed for use by the applicant does not comply with the
   antenna performance standards contained in §  25.209(a) and (b), the
   applicant must provide, as an exhibit to its application, antenna gain
   test plots pursuant to §  25.132(b)(3).

   (iii) An ESV applicant proposing to implement a transmitter under
   paragraph (a)(1)(ii)(A) of this section, must provide a certification
   from the equipment manufacturer stating that the antenna tracking
   system will maintain a pointing error of less than or equal to 0.2
   between the orbital location of the target satellite and the axis of
   the main lobe of the ESV antenna and that the antenna tracking system
   is capable of ceasing emissions within 100 milliseconds if the angle
   between the orbital location of the target satellite and the axis of
   the main lobe of the ESV antenna exceeds 0.5DEG.

   (iv) An ESV applicant proposing to implement a transmitter under
   paragraph (a)(1)(ii)(B) of this section must:

   (A) Declare, in their application, a maximum antenna pointing error and
   demonstrate that the maximum antenna pointing error can be achieved
   without exceeding the off-axis EIRP spectral-density limits in
   paragraph (a)(1)(A) of this section; and

   (B) Demonstrate that the ESV transmitter can detect if the transmitter
   exceeds the declared maximum antenna pointing error and can cease
   transmission within 100 milliseconds if the angle between the orbital
   location of the target satellite and the axis of the main lobe of the
   ESV antenna exceeds the declared maximum antenna pointing error, and
   will not resume transmissions until the angle between the orbital
   location of the target satellite and the axis of the main lobe of the
   ESV antenna is less than or equal to the declared maximum antenna
   pointing error.

   (2) An ESV applicant proposing to implement a transmitter under
   paragraph (a)(2) of this section and using off-axis EIRP
   spectral-densities in excess of the levels in paragraph (a)(1)(i) or
   (a)(3)(i) of this section shall provide the following certifications
   and demonstration(s) as exhibits to its earth station application:

   (i) A statement from the target satellite operator certifying that the
   proposed operation of the ESV has the potential to create harmful
   interference to satellite networks adjacent to the target satellite(s)
   that may be unacceptable.

   (ii) A statement from the target satellite operator certifying that the
   power-density levels that the ESV applicant provided to the target
   satellite operator are consistent with the existing coordination
   agreements between its satellite(s) and the adjacent satellite systems
   within 6DEG of orbital separation from its satellite(s).

   (iii) A statement from the target satellite operator certifying that it
   will include the power-density levels of the ESV applicant in all
   future coordination agreements.

   (iv) Except for variable power ESV applicants, a demonstration from the
   ESV operator that the ESV system is capable of detecting and
   automatically ceasing emissions within 100 milliseconds when the
   transmitter exceeds the off-axis EIRP spectral-densities supplied to
   the target satellite operator. Variable power ESV applicants shall
   provide a detailed showing that an individual ESV terminal is capable
   of automatically ceasing or reducing emissions within 100 milliseconds
   if the ESV transmitter exceeds the off-axis EIRP spectral-densities
   supplied to the target satellite operator; that the individual
   transmitter is self-monitoring and capable of shutting itself off; and
   that one or more transmitters are capable of automatically ceasing or
   reducing emissions within 100 milliseconds of receiving the appropriate
   command from the system's central control and monitoring station if the
   aggregate off-axis EIRP spectral-densities of the transmitter or
   transmitters exceed the off-axis EIRP spectral-densities supplied to
   the target satellite operator.

   (3) An ESV applicant proposing to implement an ESV system under
   paragraph (a)(3) of this section and using variable power-density
   control of individual simultaneously transmitting co-frequency ESV
   earth stations in the same satellite receiving beam shall provide the
   information in paragraphs (b)(3)(i) and (b)(3)(ii) of this section as
   exhibits to its ESV application. The International Bureau will place
   these showings on Public Notice along with the application.

   (i) The ESV applicant shall provide a detailed showing of the measures
   it intends to employ to maintain the effective aggregate EIRP-density
   from all simultaneously transmitting co-frequency terminals operating
   with the same satellite transponder at least 1 dB below the
   EIRP-density limits defined in paragraph (a)(1)(i) of this section. In
   this context the term "effective" means that the resultant co-polarized
   and cross-polarized EIRP-density experienced by any GSO or non-GSO
   satellite shall not exceed that produced by a single ESV transmitter
   operating at 1 dB below the limits defined in paragraph (a)(1)(i) of
   this section.

   (ii) The ESV applicant shall provide a detailed showing that an
   individual ESV terminal is capable of automatically ceasing emissions
   within 100 milliseconds if the ESV transmitter exceeds the off-axis
   EIRP-density limit specified in paragraph (a)(3)(i) of this section and
   that the individual transmitter is self-monitoring and capable of
   shutting itself off. The ESV applicant shall also provide a detailed
   showing that one or more transmitters are capable of automatically
   ceasing or reducing emissions within 100 milliseconds of receiving the
   appropriate command from the system's central control and monitoring
   station if the aggregate off-axis EIRP spectral-densities of the
   transmitter or transmitters exceed the off-axis EIRP-density limits
   specified in paragraph (a)(3)(i) of this section.

   (4) There shall be an exhibit included with the application describing
   the geographic area(s) in which the ESVs will operate.

   (5) The point of contact referred to in paragraph (a)(3) of this
   section and, if applicable paragraph (a)(6) of this section, must be
   included in the application.

   (6) ESVs that exceed the radiation guidelines of §  1.1310 of this
   chapter, Radiofrequency radiation exposure limits, must provide, with
   their environmental assessment, a plan for mitigation of radiation
   exposure to the extent required to meet those guidelines.

   (7) Except for ESV systems operating pursuant to paragraph (a)(2) of
   this section, ESV systems authorized pursuant to this section shall be
   eligible for a license that lists ALSAT as an authorized point of
   communication.

   (c) Operations of ESVs in the 14.0-14.2 GHz (Earth-to-space) frequency
   band within 125 km of the NASA TDRSS facilities on Guam (located at
   latitude: 13DEG36'55'' N, longitude 144DEG51'22'' E) or White Sands,
   New Mexico (latitude: 32DEG20'59'' N, longitude 106DEG36'31'' W and
   latitude: 32DEG32'40'' N, longitude 106DEG36'48'' W) are subject to
   coordination through the National Telecommunications and Information
   Administration (NTIA) Interdepartment Radio Advisory Committee (IRAC).
   When NTIA seeks to provide similar protection to future TDRSS sites
   that have been coordinated through the IRAC Frequency Assignment
   Subcommittee process, NTIA will notify the Commission that the site is
   nearing operational status. Upon public notice from the Commission, all
   Ku-band ESV operators must cease operations in the 14.0-14.2 GHz band
   within 125 km of the new TDRSS site until after NTIA/IRAC coordination
   for the new TDRSS facility is complete. ESV operations will then again
   be permitted to operate in the 14.0-14.2 GHz band within 125 km of the
   new TDRSS site, subject to any operational constraints developed in the
   coordination process.

   (d) Operations of ESVs in the 14.47-14.5 GHz (Earth-to-space) frequency
   band within (a) 45 km of the radio observatory on St. Croix, Virgin
   Islands (latitude 17DEG46' N, longitude 64DEG35' W); (b) 125 km of the
   radio observatory on Mauna Kea, Hawaii (at latitude 19DEG48' N,
   longitude 155DEG28' W); and (c) 90 km of the Arecibo Observatory on
   Puerto Rico (latitude 18DEG20'46'' W, longitude 66DEG45'11'' N) are
   subject to coordination through the National Telecommunications and
   Information Administration (NTIA) Interdepartment Radio Advisory
   Committee (IRAC).
