§ 25.226 Blanket licensing provisions for domestic, U.S. Vehicle-Mounted
Earth Stations (VMESs) receiving in the 10.95-11.2 GHz (space-to-Earth),
11.45-11.7 GHz (space-to-Earth), and 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) The following ongoing requirements govern all VMES 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) frequency bands receiving from and transmitting to
geostationary orbit satellites in the fixed-satellite service. VMES
licensees shall comply with the requirements in either paragraph
(a)(1), (a)(2) or (a)(3) of this section and all of the requirements
set forth in paragraphs (a)(4) through (a)(9) and paragraphs (c), (d),
and (e) of this section. Paragraph (b) of this section identifies items
that shall be included in the application for VMES operations to
demonstrate that these ongoing requirements will be met.
(1) The following requirements shall apply to a VMES that uses
transmitters with off-axis EIRP spectral-densities lower than or equal
to the levels in paragraph (a)(1)(i) of this section. A VMES, or VMES
system, operating under this section shall provide a detailed
demonstration as described in paragraph (b)(1) of this section. The
VMES transmitter also shall comply with the antenna pointing and
cessation of emission requirements in paragraphs (a)(1)(ii) and
(a)(1)(iii) of this section.
(i) A VMES system shall not exceed the off-axis EIRP spectral-density
limits and conditions defined in paragraphs (a)(1)(i)(A) through (D) of
this section.
(A) The off-axis EIRP spectral-density emitted from the VMES, in the
plane of the geostationary satellite orbit (GSO) as it appears at the
particular earth station location, shall not exceed the following
values:
15-10log(N)-25logθ dBW/4kHz for 1.5° ≤ θ ≤ 7°
−6 −10log(N) dBW/4kHz for 7° < θ ≤ 9.2°
18 −10log(N)-25logθ dBW/4kHz for 9.2° < θ ≤ 48°
−24 −10log(N) dBW/4kHz for 48° < θ ≤ 85°
−14 −10log(N) dBW/4kHz for 85° < θ ≤ 180°
where theta (θ) is the angle in degrees from the line connecting the
focal point of the antenna to the orbital location of the target
satellite, 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
location of the target satellite. For VMES networks using frequency
division multiple access (FDMA) or time division multiple access (TDMA)
techniques, N is equal to one. For VMES networks using multiple
co-frequency transmitters that have the same EIRP, N is the maximum
expected number of co-frequency simultaneously transmitting VMES earth
stations in the same satellite receiving beam. For the purpose of this
section, the peak EIRP of an individual sidelobe shall not exceed the
envelope defined above for θ between 1.5° and 7.0°. For θ greater than
7.0°, the envelope shall 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 VMES shall
not exceed the following values:
18−10log(N)−25logθ dBW/4kHz for 3.0° ≤ θ ≤ 48°
−24−10log(N) dBW/4kHz for 48° < θ ≤ 85°
−14−10log(N) dBW/4kHz for 85° < θ ≤ 180°
where θ and N are defined in paragraph (a)(1)(i)(A) of this section.
This off-axis EIRP spectral-density applies in any plane that includes
the line connecting the focal point of the antenna to the orbital
location of the target satellite with the exception of the plane of the
GSO as defined in paragraph (a)(1)(i)(A) of this section. For the
purpose of this subsection, the envelope shall be exceeded by no more
than 10% of the sidelobes provided no individual sidelobe exceeds the
gain envelope given above by more than 6 dB. The region of the main
reflector spillover energy is to be interpreted as a single lobe and
shall not exceed the envelope by more than 6 dB.
(C) In all directions, the off-axis EIRP spectral-density for
cross-polarized signals emitted from the VMES shall not exceed the
following values:
5−10log(N)−25logθ dBW/4kHz for 1.8° ≤ θ ≤ 7.0°
−16−10log(N) dBW/4kHz for 7.0° < θ ≤ 9.2°
where θ and N are defined as set forth in paragraph (a)(1)(i)(A) of
this section. This EIRP spectral-density applies in any plane that
includes the line connecting the focal point of the antenna to the
target satellite.
(D) For non-circular VMES antennas, the major axis of the antenna shall
be aligned with the tangent to the arc of the GSO at the orbital
location of the target satellite, to the extent required to meet the
specified off-axis EIRP spectral-density criteria.
(ii) Each VMES transmitter shall meet one of the following antenna
pointing requirements:
(A) Each VMES transmitter shall 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 VMES antenna, or
(B) Each VMES transmitter shall declare a maximum antenna pointing
error that may be greater than 0.2° provided that the VMES does not
exceed the off-axis EIRP spectral-density limits in paragraph (a)(1)(i)
of this section, taking into account the antenna pointing error.
(iii) Each VMES transmitter shall meet one of the following cessation
of emission requirements:
(A) For VMESs operating under paragraph (a)(1)(ii)(A) of this section,
all emissions from the VMES 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 VMES antenna exceeds
0.5°, and transmission shall not resume until such angle is less than
or equal to 0.2°, or
(B) For VMES transmitters operating under paragraph (a)(1)(ii)(B) of
this section, all emissions from the VMES 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 VMES antenna
exceeds the declared maximum antenna pointing error and shall not
resume transmissions until such angle is less than or equal to the
declared maximum antenna pointing error.
(2) The following requirements shall apply to a VMES that uses off-axis
EIRP spectral-densities in excess of the levels in paragraph (a)(1)(i)
of this section. A VMES, or VMES system, operating under this
subsection shall file certifications and provide a detailed

located within 6 degrees longitude of the target satellite, the VMES
operator shall accept the power-density levels that would accommodate
that adjacent satellite.
(iii) The VMES shall operate in accordance with the off-axis EIRP
spectral-densities that the VMES supplied to the target satellite
operator in order to obtain the certifications listed in paragraph
(b)(2) of this section. The VMES shall automatically cease emissions
within 100 milliseconds if the VMES transmitter exceeds the off-axis
EIRP spectral-densities supplied to the target satellite operator.
(3) The following requirements shall apply to a VMES system that uses
variable power-density control of individual simultaneously
transmitting co-frequency VMES earth stations in the same satellite
receiving beam. A VMES system operating under this subsection shall
file certifications and provide a detailed demonstration as described
in paragraph (b)(3) of this section.
(i) Except as defined under paragraph (a)(3)(ii) of this section, the
effective aggregate EIRP-density from all terminals shall be at least 1
dB below the off-axis EIRP-density limits defined in paragraphs
(a)(1)(i)(A) through (C) 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 VMES transmitter operating 1 dB below
the limits defined in paragraphs (a)(1)(i)(A) through (C) of this

referred to in the certifications required by paragraph (b)(3) of this
section.

detailing the effective aggregate EIRP-density levels resulting from
its operation, in compliance with paragraph (b)(3)(iii) of this
section.
(4) An applicant filing to operate a VMES terminal or system and
planning to use a contention protocol shall certify that its contention
protocol use will be reasonable.

bands shall receive protection from interference caused by space
stations other than the target space station only to the degree to
which harmful interference would not be expected to be caused to an
earth station employing an antenna conforming to the referenced
patterns defined in § 25.209(a) and (b) and stationary at the location
at which any interference occurred.
(9) Each VMES terminal shall automatically cease transmitting within
100 milliseconds upon loss of reception of the satellite downlink
