Sec.  25.222   Blanket Licensing provisions for Earth Stations on Vessels (ESVs)
receiving 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) frequency bands and
transmitting in the 14.0–14.5 GHz (Earth-to-space) frequency band, operating
with Geostationary Satellites in the Fixed-Satellite Service.

   (a) All applications for licenses for ESVs receiving 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) frequency bands, and transmitting in the 14.0–14.5 GHz
   (Earth-to-space)  frequency  band,  to Geostationary Satellites in the
   fixed-satellite service shall provide sufficient data to demonstrate that
   the  ESV  operations  meet  the  following criteria, which are ongoing
   requirements that govern all ESV licensees and operations in these bands:

   (1) The off-axis EIRP spectral density for co-polarized signals, emitted
   from the ESV in the plane of the geostationary satellite orbit as it appears
   at the particular earth station location ( i.e. , the plane determined by
   the  focal point of the antenna and the line tangent to the arc of the
   geostationary satellite orbit at the position of the target satellite),
   shall not exceed the following values:

   15 − 25log(Θ) − 10log(N) dBW/4kHz for 1.25 ° ≤ Θ ≤ 7.0 °

   −6 − 10 log(N) dBW/4kHz for 7.0 ° < Θ ≤ 9.2 °

   18 − 25log(Θ) − 10log(N) dBW/4kHz for 9.2 ° < Θ ≤ 48 °

   −24 − 10log(N) dBW/4kHz for 48 ° < Θ ≤ 180 °

   where Θ is the angle in degrees from the axis of the main lobe. For an ESV
   network using frequency division multiple access (FDMA) or time division
   multiple access (TDMA) technique, N is equal to one. For an ESV network
   using code division multiple access (CDMA) technique, N is the maximum
   number of co-frequency simultaneously transmitting earth stations in the
   same satellite receiving beam.

   (2)  In  all  other directions, the off-axis EIRP spectral density for
   co-polarized signals emitted from the ESV shall not exceed the following
   values:

   18 − 25log(Θ) − 10log(N) dBW/4kHz for 1.25 ° ≤ Θ ≤ 48 °

   −24 − 10log(N) dBW/4kHz for 48 ° < Θ ≤ 180 °

   where Θ and N are defined as set forth in paragraph (a)(1) of this section.

   (3) For Θ>7 °, the values given in paragraphs (a)(1) of this section may be
   exceeded  by no more than 10% of the sidelobes, provided no individual
   sidelobe exceeds the criteria given by more than 3 dB.

   (4)  In  all  directions,  the  off-axis  EIRP  spectral  density  for
   cross-polarized signals emitted from the ESV shall not exceed the following
   values:

   5 − 25log(Θ) − 10log(N) dBW/4kHz for 1.8 ° ≤ Θ ≤ 7 °

   −16 − 10log(N) dBW/4kHz for 7 ° ≤ Θ ≤ 9.2 °

   where Θ and N are defined as set forth in paragraph (a)(1) of this section.

   (5) For non-circular ESV antennas, the major axis of the antenna will be
   aligned with the tangent to the geostationary satellite orbital arc at the
   target satellite point, to the extent required to meet specified off-axis
   e.i.r.p. criteria.

   (6) A pointing error of less than 0.2 °, between the orbital location of the
   target satellite and the axis of the main lobe of the ESV antenna.

   (7)  All  emissions  from the ESV shall automatically cease 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 0.5 °, and
   transmission will not resume until such angle is less than 0.2 °.

   (8) There shall be a point of contact in the United States, with phone
   number and address included with the application, available 24 hours a day,
   seven days a week, with authority and ability to cease all emissions from
   the ESVs, either directly or through the facilities of a U.S. Hub or a Hub
   located in another country with which the U.S. has a bilateral agreement
   that enables such cessation of emissions.

   (9) ESVs that exceed the radiation guidelines of  Sec. 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.

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

   (b) Applications for ESV operation in the 14.0–14.5 GHz (Earth-to-space) to
   geostationary satellites in the fixed-satellite service must include, in
   addition  to  the  particulars of operation identified on Form 312 and
   associated Schedule B, the following data for each earth station antenna
   type:

   (1)  A  series  of e.i.r.p. density charts or tables, calculated for a
   production  earth  station  antenna,  based on measurements taken on a
   calibrated antenna range at 14.25 GHz, with the off-axis e.i.r.p. envelope
   set forth in paragraphs (a)(1) through (a)(4) of this section superimposed,
   as follows:

   (i) Showing off-axis co-polarized e.i.r.p. spectral density in the azimuth
   plane, for off-axis angles from minus 10 ° to plus 10 ° and from minus 180 ° to
   plus 180 °.

   (ii)  Showing  off-axis  co-polarized e.i.r.p. spectral density in the
   elevation plane, at off-axis angles from 0 ° to plus 30 °.

   (iii) Showing off-axis cross-polarized e.i.r.p. spectral density in the
   azimuth plane, at off-axis angles from minus 10 ° to plus 10 °.

   (iv) Showing off-axis cross-polarized e.i.r.p. spectral density in the
   elevation plane, at off-axis angles from minus 10 ° to plus 10 °; or

   (2)  A series of gain charts or tables, for a production earth station
   antenna, measured on a calibrated antenna range at 14.25 GHz, with the Earth
   station antenna gain envelope set forth in  Sec. 25.209(a) and (b) superimposed,
   for the same planes and ranges enumerated in paragraphs (b)(1)(i) through
   (b)(1)(iv) of this section, that, combined with input power density entered
   in Schedule B, demonstrates that off-axis e.i.r.p. spectral density envelope
   set forth in paragraphs (a)(1) through (a)(4) of this section will be met;
   or

   (3)  A certification that the ESV antenna conforms to the gain pattern
   criteria of  Sec. 25.209(a) and (b), that, combined with input power density
   entered in Schedule B, demonstrates that the off-axis e.i.r.p. spectral
   density envelope set forth in paragraphs (a)(1) through (a)(4) of this
   section will be met.

   (c) ESVs receiving 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) frequency bands, and
   transmitting in the 14.0–14.5 GHz (Earth-to-space) frequency band shall
   operate with the following provisions:

   (1)  For  each  ESV transmitter a record of the ship location ( i.e. ,
   latitude/longitude), transmit frequency, channel bandwidth and satellite
   used shall be time annotated and maintained for a period of not less than 1
   year. Records will be recorded at time intervals no greater than every 20
   minutes while the ESV is transmitting. The ESV operator will make this data
   available  upon  request  to  a  coordinator,  fixed  system operator,
   fixed-satellite system operator, NTIA, or the Commission within 24 hours of
   the request.

   (2)  ESV operators communicating with vessels of foreign registry must
   maintain detailed information on each vessel's country of registry and a
   point of contact for the relevant administration responsible for licensing
   ESVs.

   (3) ESV operators shall control all ESVs by a Hub earth station located in
   the United States, except that an ESV on U.S.-registered vessels may operate
   under control of a Hub earth station location outside the United States
   provided the ESV operator maintains a point of contact within the United
   States that will have the capability and authority to cause an ESV on a
   U.S.-registered vessel to cease transmitting if necessary.

   (d) 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:
   13 °  36'  55"  N, longitude 144 ° 51' 22" E) or White Sands, New Mexico
   (latitude: 32 ° 20' 59" N, longitude 106 ° 36' 31" W and latitude: 32 ° 32' 40"
   N,  longitude  106 ° 36' 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.

   (e) 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  17 °  46'  N,  longitude  64 ° 35' W); b) 125 km of the radio
   observatory on Mauna Kea, Hawaii (at latitude 19 ° 48' N, longitude 155 ° 28'
   W); and c) 90 km of the Arecibo Observatory on Puerto Rico (latitude 18 ° 20'
   46" W, longitude 66 ° 45' 11" N) are subject to coordination through the
   National  Telecommunications  and  Information  Administration  (NTIA)
   Interdepartment Radio Advisory Committee (IRAC).

   (f)   In  the  10.95–11.2  GHz  (space-to-Earth)  and  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.
