§ 25.114 Applications for space station authorizations.
Link to an amendment published at 85 FR 52450 , Aug. 25, 2020.
(a)(1) A license application filed pursuant to § 25.110(b)(2) for a GSO
space station or NGSO space station or space-station constellation must
comprise a comprehensive proposal and must be submitted on FCC Form
312, Main Form and Schedule S, with attached exhibits required by
paragraph (d) of this section.
(2) An application for blanket authority for an NGSO constellation of
space stations that are not all technically identical must provide the
information required by paragraphs (c) and (d) of this section for each
type of station in the constellation.
(3) For an application filed pursuant to the two-step procedure in
§ 25.110(b)(3), the filing pursuant to § 25.110(b)(3)(iii) must be
submitted on FCC Form 312, Main Form and Schedule S, with attached
exhibits as required by paragraph (d) of this section, and must
constitute a comprehensive proposal.
(b) Each application for a new or modified space station authorization
must contain the formal waiver required by 47 U.S.C. 304.
(c) The following information shall be filed on FCC Form 312, Main Form
and Schedule S:
(1) Name, address, and telephone number of the applicant;
(2) Name, address, and telephone number of the person(s), including
counsel, to whom inquiries or correspondence should be directed;
(3) Type of authorization requested (e.g., launch authority, station
license, modification of authorization);
(4)(i) For each space station transmitting and receiving antenna beam
(including telemetry and tracking beams but not command beams), specify
channel center frequencies and bandwidths and polarization plan. For
command beams, specify each of the center frequencies within a 5 MHz
range or a range of 2 percent of the assigned bandwidth, whichever is
smaller, and the polarization plan. If the space station can vary
channel bandwidth in a particular frequency band with on-board
processing, specify only the range of frequencies in that band over
which the beam can operate and the polarization plan.
(ii) Specify maximum EIRP and maximum EIRP density for each space
station transmitting antenna beam. If the satellite uses shapeable
antenna beams, as defined in § 25.103, specify instead maximum possible
EIRP and maximum possible EIRP density within each shapeable beam's
proposed coverage area. Provide this information for each frequency
band in which the transmitting antenna would operate. For bands below
15 GHz, specify EIRP density in dBW/4 kHz; for bands at and above 15
GHz, specify EIRP density in dBW/MHz. If the EIRP density varies over
time, specify the maximum possible EIRP density.
(iii)-(iv) [Reserved]
(v) For each space station receiving beam other than command beams,
specify the gain-to-temperature ratio at beam peak. For receiving beams
fed into transponders, also specify the minimum and maximum saturation
flux density at beam peak. If the satellite uses shapeable beams,
specify the minimum and maximum gain-to-temperature ratio within each
shapeable beam's proposed coverage area, and for shapeable receiving
beams fed into transponders, specify the minimum and maximum saturation
power flux density within the 0 dB relative antenna gain isoline.
Provide this information for each frequency band in which the receiving
beam can operate. For command beams, specify the beam peak flux density
at the command threshold;
(vi)(A) For space stations in geostationary orbit, specify predicted
space station antenna gain contour(s) for each transmit and receive
antenna beam, except for beams where the contour at 8 dB below peak
falls entirely beyond the edge of the visible Earth. These contour(s)
should be plotted on an area map at 2 dB intervals down to 10 dB below
the peak gain and at 5 dB intervals between 10 dB and 20 dB below the
peak gain. Applicants must present this information in a GIMS-readable
format.
(B) For space stations in non-geostationary orbits, specify for each
unique orbital plane the predicted antenna gain contour(s) for each
transmit and receive antenna beam for one space station if all space
stations are identical in the constellation. If individual space
stations in the constellation have different antenna beam
configurations, specify the predicted antenna gain contours for each
transmit and receive beam for each space station type and orbit or
orbital plane requested. The contours should be plotted on an area map
with the beam depicted on the surface of the earth with the space
stations' peak antenna gain pointed at nadir to a latitude and
longitude within the proposed service area. The contour(s) should be
plotted at 2 dB intervals down to 10 dB below the peak gain and at 5 dB
intervals between 10 dB and 20 dB below the peak gain. For
intersatellite links, specify the peak antenna gain and 3 dB beamwidth.
(C) For space stations with shapeable antenna beams, specify the
contours, as defined in paragraph (c)(4)(vi)(A) or (B) of this section,
for the transmitting beam configuration that results in the highest
EIRP density for the beams listed in paragraph (c)(4)(ii) of this
section and for the receiving beam configuration with the smallest
gain-to-temperature ratio and the highest required saturation power
flux density for the beams listed in paragraph (c)(4)(v) of this
section. If the shapeable beams are also steerable, include the
contours that would result from moving the beam peak around the limit
of the effective beam peak area and the 0 dB relative antenna gain
isoline. The proposed maximum coverage area must be clearly specified.
(D) For a space station with steerable beams that are not shapeable,
specify the applicable contours, as defined in paragraph (c)(4)(vi)(A)
or (c)(4)(vi)(B) of this section, with a description of a proposed
coverage area for each steerable beam or provide the contour
information described in paragraph (c)(4)(vi)(C) of this section for
each steerable beam.
(vii) For geostationary satellites with large numbers of identical
fixed spot beams, other than DBS satellites, applicants may, as an
alternative to submitting the information described in paragraph
(c)(4)(vi) of this section with respect to these beams, provide the
predicted antenna gain contours for one transmit and receive antenna
beam, together with one of the following:
(A) An area map showing all of the spot beams depicted on the surface
of the Earth;
(B) A table identifying the maximum antenna gain point(s) in latitude
and longitude to the nearest 0.1 degree; or
(C) A map of the isolines formed by combining all of the spot beams
into one or more composite beams. For non-geostationary satellites with
large numbers of identical fixed beams on each satellite, applicants
may, as an alternative to submitting the information described in
paragraph (c)(4)(vi) of this section with respect to those beams,
specify the predicted antenna gain contours for one transmit and
receive beam pointed to nadir, together with an area map showing all of
the spot beams depicted on the surface of the earth with the

information necessary to comply with the policies and procedures set
forth in Rules and Policies Pertaining to the Use of Radio Frequencies
in a Land Mobile Satellite Service, 2 FCC Rcd 485 (1987) (Available at
address in § 0.445 of this chapter.);
(9) Applications to license multiple space station systems in the
non-voice, non-geostationary mobile-satellite service under blanket
operating authority shall also provide all information specified in
§ 25.142; and
(10) An application for space station authorization in the 1.6/2.4 GHz
or 2 GHz Mobile-Satellite Service must include information required by
§ 25.143(b);
(11) Applications for space stations in the Direct Broadcast Satellite
Service must include a clear and detailed statement of whether the
space station is to be operated on a broadcast or non-broadcast basis;
(12) The information required by § 25.146, if the application is for an
NGSO FSS system authorization within the 10.7-30 GHz band.
(13) For satellite applications in the Direct Broadcast Satellite
Service, if the proposed system's technical characteristics differ from
those specified in the Appendix 30 BSS Plans, the Appendix 30A feeder
link Plans, Annex 5 to Appendix 30 or Annex 3 to Appendix 30A of the
ITU Radio Regulations, each applicant must provide:
(i) The information requested in Appendix 4 of the ITU Radio
Regulations. Further, applicants must provide sufficient technical
showing that the proposed system could operate satisfactorily if all
assignments in the BSS and feeder link Plans were implemented.
(ii) Analyses of the proposed system with respect to the limits in
Annex 1 to Appendices 30 and 30A of the ITU Radio Regulations.
(14) A description of the design and operational strategies that will
be used to mitigate orbital debris, including the following
information:
(i) A statement that the space station operator has assessed and
limited the amount of debris released in a planned manner during normal
operations, and has assessed and limited the probability of the space
station becoming a source of debris by collisions with small debris or
meteoroids that could cause loss of control and prevent post-mission
disposal;
(ii) A statement that the space station operator has assessed and
limited the probability of accidental explosions during and after
completion of mission operations. This statement must include a
demonstration that debris generation will not result from the
conversion of energy sources on board the spacecraft into energy that
fragments the spacecraft. Energy sources include chemical, pressure,
and kinetic energy. This demonstration should address whether stored
energy will be removed at the spacecraft's end of life, by depleting
residual fuel and leaving all fuel line valves open, venting any
pressurized system, leaving all batteries in a permanent discharge
state, and removing any remaining source of stored energy, or through
other equivalent procedures specifically disclosed in the application;
(iii) A statement that the space station operator has assessed and
limited the probability of the space station becoming a source of
debris by collisions with large debris or other operational space
stations. Where a space station will be launched into a low-Earth orbit
that is identical, or very similar, to an orbit used by other space
stations, the statement must include an analysis of the potential risk
of collision and a description of what measures the space station
operator plans to take to avoid in-orbit collisions. If the space
station operator is relying on coordination with another system, the
statement must indicate what steps have been taken to contact, and
ascertain the likelihood of successful coordination of physical
operations with, the other system. The statement must disclose the
accuracy—if any—with which orbital parameters of non-geostationary
satellite orbit space stations will be maintained, including apogee,
perigee, inclination, and the right ascension of the ascending node(s).
In the event that a system is not able to maintain orbital tolerances,
i.e., it lacks a propulsion system for orbital maintenance, that fact
should be included in the debris mitigation disclosure. Such systems
must also indicate the anticipated evolution over time of the orbit of
the proposed satellite or satellites. Where a space station requests
the assignment of a geostationary-Earth orbit location, it must assess
whether there are any known satellites located at, or reasonably
expected to be located at, the requested orbital location, or assigned
in the vicinity of that location, such that the station keeping volumes
of the respective satellites might overlap. If so, the statement must
include a statement as to the identities of those parties and the
measures that will be taken to prevent collisions;
(iv) A statement detailing the post-mission disposal plans for the
space station at end of life, including the quantity of fuel—if
any—that will be reserved for post-mission disposal maneuvers. For
geostationary-Earth orbit space stations, the statement must disclose
the altitude selected for a post-mission disposal orbit and the
calculations that are used in deriving the disposal altitude. The
statement must also include a casualty risk assessment if planned
post-mission disposal involves atmospheric re-entry of the space
station. In general, an assessment should include an estimate as to
whether portions of the spacecraft will survive re-entry and reach the
surface of the Earth, as well as an estimate of the resulting
probability of human casualty. Applicants for space stations to be used
only for commercial remote sensing may, in lieu of submitting detailed
post-mission disposal plans to the Commission, certify that they have
submitted such plans to the National Oceanic and Atmospheric
Administration for review.
(v) For non-U.S.-licensed space stations, the requirement to describe
the design and operational strategies to minimize orbital debris risk
can be satisfied by demonstrating that debris mitigation plans for the
space station(s) for which U.S. market access is requested are subject
to direct and effective regulatory oversight by the national licensing
authority.
(15) Each applicant for a space station license in the 17/24 GHz
broadcasting-satellite service shall include the following information
as an attachment to its application:
(i) If the applicant proposes to operate in the 17.3-17.7 GHz frequency
band, a demonstration that the proposed space station will comply with
the power flux density limits in § 25.208(w) unless the applicant
provides a certification under paragraph (d)(15)(ii) of this section.
(ii) In cases where the proposed space station will not comply with the
power flux density limits set forth in § 25.208(w) of this part, the
applicant will be required to provide a certification that all
potentially affected parties acknowledge and do not object to the use
of the applicant's higher power flux densities. The affected parties
with whom the applicant must coordinate are those GSO 17/24 GHz BSS
satellite networks located up to ±6° away for excesses of up to 3 dB
above the power flux-density levels specified in § 25.208(w) of this
part, and up to ±10° away greater for excesses greater than 3 dB above
those levels.
(iii) If the applicant proposes to provide international service in the
17.7-17.8 GHz frequency band, a certification that the proposed space
station will comply with the power flux density limits in § 25.208(c).
(iv) Any information required by § 25.264(a)(6), 25.264(b)(4), or
25.264(d).
(16) In addition to the requirements of paragraph (d)(15) of this
section, each applicant for a license to operate a 17/24 GHz BSS space
station that will be used to provide video programming directly to
consumers in the United States, that will not meet the requirements of
§ 25.225 of this part, must include as an attachment to its application
a technical analysis demonstrating that providing video programming
service to consumers in Alaska and Hawaii that is comparable to the
video programming service provided to consumers in the 48 contiguous
United States (CONUS) is not feasible as a technical matter or that,
while technically feasible, such service would require so many
compromises in satellite design and operation as to make it
economically unreasonable.
(17) [Reserved]
(18) For space stations in the Direct Broadcast Satellite service or
the 17/24 GHz broadcasting-satellite service, maximum orbital
eccentricity.

§ 25.114 Applications for space station authorizations.
* * * * *
(d) * * *
(14) A description of the design and operational strategies that will
be used to mitigate orbital debris, including the following
information:
(i) A statement that the space station operator has assessed and
limited the amount of debris released in a planned manner during normal
operations. Where applicable, this statement must include an orbital
debris mitigation disclosure for any separate deployment devices,
distinct from the space station launch vehicle, that may become a
source of orbital debris;
(ii) A statement indicating whether the space station operator has
assessed and limited the probability that the space station(s) will
become a source of debris by collision with small debris or meteoroids
that would cause loss of control and prevent disposal. The statement
must indicate whether this probability for an individual space station
is 0.01 (1 in 100) or less, as calculated using the NASA Debris
Assessment Software or a higher fidelity assessment tool;
(iii) A statement that the space station operator has assessed and
limited the probability, during and after completion of mission
operations, of accidental explosions or of release of liquids that will
persist in droplet form. This statement must include a demonstration
that debris generation will not result from the conversion of energy
sources on board the spacecraft into energy that fragments the
spacecraft. Energy sources include chemical, pressure, and kinetic
energy. This demonstration should address whether stored energy will be
removed at the spacecraft's end of life, by depleting residual fuel and
leaving all fuel line valves open, venting any pressurized system,
leaving all batteries in a permanent discharge state, and removing any
remaining source of stored energy, or through other equivalent
procedures specifically disclosed in the application;
(iv) A statement that the space station operator has assessed and
limited the probability of the space station(s) becoming a source of
debris by collisions with large debris or other operational space
stations.
(A) Where the application is for an NGSO space station or system, the
following information must also be included:
(1) A demonstration that the space station operator has assessed and
limited the probability of collision between any space station of the
system and other large objects (10 cm or larger in diameter) during the
total orbital lifetime of the space station, including any de-orbit
phases, to less than 0.001 (1 in 1,000). The probability shall be
calculated using the NASA Debris Assessment Software or a higher
fidelity assessment tool. The collision risk may be assumed zero for a
space station during any period in which the space station will be
maneuvered effectively to avoid colliding with large objects.
(2) The statement must identify characteristics of the space
station(s)' orbits that may present a collision risk, including any
planned and/or operational space stations in those orbits, and indicate
what steps, if any, have been taken to coordinate with the other
spacecraft or system, or what other measures the operator plans to use
to avoid collision.
(3) If at any time during the space station(s)' mission or de-orbit
phase the space station(s) will transit through the orbits used by any
inhabitable spacecraft, including the International Space Station, the
statement must describe the design and operational strategies, if any,
that will be used to minimize the risk of collision and avoid posing
any operational constraints to the inhabitable spacecraft.
(4) The statement must disclose the accuracy, if any, with which
orbital parameters will be maintained, including apogee, perigee,
inclination, and the right ascension of the ascending node(s). In the
event that a system is not able to maintain orbital tolerances, e.g.,
its propulsion system will not be used for orbital maintenance, that
fact must be included in the debris mitigation disclosure. Such systems
must also indicate the anticipated evolution over time of the orbit of
the proposed satellite or satellites. All systems must describe the
extent of satellite maneuverability, whether or not the space station
design includes a propulsion system.
(5) The space station operator must certify that upon receipt of a
space situational awareness conjunction warning, the operator will
review and take all possible steps to assess the collision risk, and
will mitigate the collision risk if necessary. As appropriate, steps to
assess and mitigate the collision risk should include, but are not
limited to: Contacting the operator of any active spacecraft involved
in such a warning; sharing ephemeris data and other appropriate
operational information with any such operator; and modifying space
station attitude and/or operations.
(B) Where a space station requests the assignment of a geostationary
orbit location, it must assess whether there are any known satellites
located at, or reasonably expected to be located at, the requested
orbital location, or assigned in the vicinity of that location, such
that the station keeping volumes of the respective satellites might
overlap or touch. If so, the statement must include a statement as to
the identities of those satellites and the measures that will be taken
to prevent collisions;
(v) A statement addressing the trackability of the space station(s).
Space station(s) operating in low-Earth orbit will be presumed
trackable if each individual space station is 10 cm or larger in its
smallest dimension, excluding deployable components. Where the
application is for an NGSO space station or system, the statement shall
also disclose the following:
(A) How the operator plans to identify the space station(s) following
deployment and whether space station tracking will be active or
passive;
(B) Whether, prior to deployment, the space station(s) will be
registered with the 18th Space Control Squadron or successor entity;
and
(C) The extent to which the space station operator plans to share
information regarding initial deployment, ephemeris, and/or planned
maneuvers with the 18th Space Control Squadron or successor entity,
other entities that engage in space situational awareness or space
traffic management functions, and/or other operators.
(vi) A statement disclosing planned proximity operations, if any, and
addressing debris generation that will or may result from the proposed
operations, including any planned release of debris, the risk of
accidental explosions, the risk of accidental collision, and measures
taken to mitigate those risks.
(vii) A statement detailing the disposal plans for the space station,
including the quantity of fuel—if any—that will be reserved for
disposal maneuvers. In addition, the following specific provisions
apply:
(A) For geostationary orbit space stations, the statement must disclose
the altitude selected for a disposal orbit and the calculations that
are used in deriving the disposal altitude.
(B) For space stations terminating operations in an orbit in or passing
through the low-Earth orbit region below 2,000 km altitude, the
statement must disclose whether the spacecraft will be disposed of
through atmospheric re-entry, specifying if direct retrieval of the
spacecraft will be used. The statement must also disclose the expected
time in orbit for the space station following the completion of the
mission.
(C) For space stations not covered by either paragraph (d)(14)(vii)(A)
or (B) of this section, the statement must indicate whether disposal
will involve use of a storage orbit or long-term atmospheric re-entry
and rationale for the selected disposal plan.
(D) For all space stations under paragraph (d)(14)(vii) (B) or (C) of
this section, the following additional specific provisions apply:
(1) The statement must include a demonstration that the probability of
success of the chosen disposal method will be 0.9 or greater for any
individual space station. For space station systems consisting of
multiple space stations, the demonstration should include additional
information regarding efforts to achieve a higher probability of
success, with a goal, for large systems, of a probability of success
for any individual space station of 0.99 or better. For space stations
under paragraph (d)(14)(vii)(B) of this section, successful disposal is
defined as atmospheric re-entry of the spacecraft within 25 years or
less following completion of the mission. For space stations under
paragraph (d)(14)(vii)(C) of this section, successful disposal will be
assessed on a case-by-case basis.
(2) If planned disposal is by atmospheric re-entry, the statement must
also include:
(i) A disclosure indicating whether the atmospheric re-entry will be an
uncontrolled re-entry or a controlled targeted reentry.
(ii) An assessment as to whether portions of any individual spacecraft
will survive atmospheric re-entry and impact the surface of the Earth
with a kinetic energy in excess of 15 joules, and demonstration that
the calculated casualty risk for an individual spacecraft using the
NASA Debris Assessment Software or a higher fidelity assessment tool is
less than 0.0001 (1 in 10,000).
(E) Applicants for space stations to be used only for commercial remote
sensing may, in lieu of submitting detailed post-mission disposal plans
to the Commission, certify that they have submitted such plans to the
National Oceanic and Atmospheric Administration for review.
(viii) For non-U.S.-licensed space stations, the requirement to
describe the design and operational strategies to minimize orbital
debris risk can be satisfied by demonstrating that debris mitigation
plans for the space station(s) for which U.S. market access is
requested are subject to direct and effective regulatory oversight by
the national licensing authority.
