§ 25.142 Licensing provisions for the non-voice, non-geostationary
Mobile-Satellite Service.
(a) Space station application requirements . (1) Each application for a
space station system authorization in the non-voice, non-geostationary
mobile-satellite service shall describe in detail the proposed
non-voice, non-geostationary mobile-satellite system, setting forth all
pertinent technical and operational aspects of the system, and the
technical and legal qualifications of the applicant. In particular,
each application shall include the information specified in § 25.114.
Applicants must also file information demonstrating compliance with all
requirements of this section, and showing, based on existing system
information publicly available at the Commission at the time of filing,
that they will not cause unacceptable interference to any non-voice,
non-geostationary mobile-satellite service system authorized to
construct or operate.
(2) Applicants for a non-voice, non-geostationary Mobile-Satellite
Service space station license must identify the power flux density
produced at the Earth's surface by each space station of their system
in the 137-138 MHz and 400.15-401 MHz bands, to allow determination of
whether coordination with terrestrial services is required under any
applicable footnote to the Table of Frequency Allocations in § 2.106
of this chapter. In addition, applicants must identify the measures
they would employ to protect the radio astronomy service in the
150.05-153 MHz and 406.1-410 MHz bands from harmful interference from
unwanted emissions.
(3) Emission limitations. (i) Applicants in the non-voice,
non-geostationary mobile-satellite service shall show that their space
stations will not exceed the emission limitations of § 25.202(f) (1),
(2) and (3), as calculated for a fixed point on the Earth's surface in
the plane of the space station's orbit, considering the worst-case
frequency tolerance of all frequency determining components, and
maximum positive and negative Doppler shift of both the uplink and
downlink signals, taking into account the system design.
(ii) Applicants in the non-voice, non-geostationary mobile-satellite
service shall show that no signal received by their satellites from
sources outside of their system shall be retransmitted with a power
flux density level, in the worst 4 kHz, higher than the level described
by the applicants in paragraph (a)(2) of this section.
(4) [Reserved]
(5) Replacement of space stations within the system license term. The
licensee need not file separate applications to construct, launch and
operate technically identical replacement satellites within the term of
the system authorization. However, the licensee shall certify to the
Commission, at least thirty days prior to launch of such replacement(s)
that:
(i) The licensee intends to launch a space station that is technically
identical to those authorized in its system license, and
(ii) Launch of this space station will not cause the licensee to exceed
the total number of operating space stations authorized by the
Commission.
(b) Operating conditions. In order to ensure compatible operations with
authorized users in the frequency bands to be utilized for operations
in the non-voice, non-geostationary mobile-satellite service,
non-voice, non-geostationary mobile-satellite service systems must
operate in accordance with the conditions specified in this section.
(1) Service limitation. Voice services may not be provided.
(2) Coordination requirements with Federal government users.
(i) The frequency bands allocated for use by the non-voice,
non-geostationary mobile-satellite service are also authorized for use
by agencies of the Federal government. The Federal use of frequencies
in the non-voice, non-geostationary mobile-satellite service frequency
bands is under the regulatory jurisdiction of the National
Telecommunications and Information Administration (NTIA).
(ii) The Commission will use its existing procedures for liaison with
NTIA to reach agreement with respect to achieving compatible operations
between Federal Government users under the jurisdiction of NTIA and
non-voice, non-geostationary Mobile-Satellite Service systems
(including user transceivers subject to blanket licensing under
§ 25.115(d)) through the frequency assignment and coordination
practices established by NTIA and the Interdepartment Radio Advisory
Committee (IRAC). In order to facilitate such frequency assignment and
coordination, applicants shall provide the Commission with sufficient
information to evaluate electromagnetic compatibility with the Federal
government use of the spectrum, and any additional information
requested by the Commission. As part of the coordination process,
applicants shall show that they will not cause unacceptable
interference to authorized Federal government users, based upon
existing system information provided by the Government. The frequency
assignment and coordination of the satellite system with Federal
Government users shall be completed prior to grant of authorization.
(iii) The Commission shall also coordinate with NTIA/IRAC with regard
to the frequencies to be shared by those earth stations of non-voice,
non-geostationary mobile-satellite service systems that are not subject
to blanket licensing under § 25.115(d), and authorized Federal
government stations in the fixed and mobile services, through the
exchange of appropriate systems information.
(3) Coordination among non-voice, non-geostationary mobile-satellite
service systems. Applicants for authority to establish non-voice,
non-geostationary mobile-satellite service systems are encouraged to
coordinate their proposed frequency usage with existing permittees and
licensees in the non-voice, non-geostationary mobile-satellite service
whose facilities could be affected by the new proposal in terms of
frequency interference or restricted system capacity. All affected
applicants, permittees, and licensees shall, at the direction of the
Commission, cooperate fully and make every reasonable effort to resolve
technical problems and conflicts that may inhibit effective and
efficient use of the radio spectrum; however, the permittee or licensee
being coordinated with is not obligated to suggest changes or
re-engineer an applicant's proposal in cases involving conflicts.
(4) Safety and distress communications. Stations operating in the
non-voice, non-geostationary mobile-satellite service that are used to
comply with any statutory or regulatory equipment carriage requirements
may also be subject to the provisions of sections 321(b) and 359 of the
Communications Act of 1934, as amended. Licensees are advised that
these provisions give priority to radio communications or signals
relating to ships in distress and prohibit a charge for the
transmission of maritime distress calls and related traffic.
(c) Reporting requirements. All operators of non-voice,
non-geostationary mobile-satellite service systems shall, on June 30 of
each year, file a report with the International Bureau and the
Commission's Columbia Operations Center in Columbia, Maryland,
containing the following information current as of May 31st of that
year:
(1) A listing of any non-scheduled space station outages for more than
thirty minutes and the cause(s) of such outages;
(2) A detailed description of the utilization made of the in-orbit
satellite system. That description should identify the percentage of
time that the system is actually used for domestic transmission, the
amount of capacity (if any) sold but not in service, and the amount of
unused system capacity; and
(3) Identification of any space stations not available for service or
otherwise not performing to specifications, the cause(s) of these
difficulties, and the date any space station was taken out of service
or the malfunction identified.
(d) Prohibition of certain agreements. No license shall be granted to
any applicant for a non-voice, non-geostationary mobile-satellite
service system if that applicant, or any companies controlling or
controlled by the applicant, shall acquire or enjoy any right, for the
purpose of handling traffic to or from the United States, its
territories or possessions, to construct or operate space segment or
earth stations in the non-voice, non-geosynchronous mobile-satellite
service, or to interchange traffic, which is denied to any other United
States company by reason of any concession, contract, understanding, or
working arrangement to which the licensee or any persons or companies
controlling or controlled by the licensee are parties.
(e) Spectrum priority. (1) The non-voice, non-geosynchronous
mobile-satellite service system that is authorized in the second
application processing round to operate in the 148-148.25 MHz,
148.75-148.855 MHz, 148.905-149.81 MHz and 150-150.05 MHz uplink
frequency bands and the 400.505-400.5517 MHz, 400.5983-400.645 MHz,
137.025-137.175 MHz, 137.333-137.4125 MHz, 137.475-137.525 MHz,
137.595-137.645 MHz, 137.753-137.787 MHz and 137.825-138 MHz downlink
frequency bands (the "System 2 licensee") will have a first priority to
apply for and use a limited amount of downlink spectrum duly allocated
worldwide and domestically to the non-voice, non-geosynchronous
mobile-satellite service by the ITU, at WRC-97 or a subsequent World
Radiocommunication Conference, and by the Commission, respectively (the
"Future Spectrum"). The System 2 licensee will be eligible to apply for
and use the first 210 kHz of Future Spectrum plus spectrum sufficient
to account for Doppler frequency shift in the Future Spectrum (the
"Supplemental Spectrum") to implement its non-voice, non-geosynchronous
mobile-satellite service system. The System 2 licensee's application
for and use of the Supplemental Spectrum is subject to the Commission's
Rules and policies, such reasonable operating conditions as may be
imposed by the Commission, and international spectrum coordination
requirements. For so long as the System 2 licensee is permitted by the
Government of France to operate in the 400.5517-400.5983 MHz band
coordinated with the French system S80-1, the Supplemental Spectrum
shall be reduced to an amount equivalent to 150 kHz of Future Spectrum
plus spectrum sufficient to account for Doppler frequency shift in the
Future Spectrum.
(2) The System 2 licensee's priority to apply for and use the
Supplemental Spectrum is conditioned on the System 2 licensee's
compliance with the terms and conditions of its second processing round
authorization, including, but not limited to, its system construction,
launch and operation milestones, and any modifications thereto, and the
Commission's Rules. The System 2 licensee's priority to apply for and
use the Supplemental Spectrum shall automatically terminate upon the
occurrence of any of the following events:
(i) The System 2 licensee being permitted to operate in the
Supplemental Spectrum;
(ii) The expiration or revocation of the System 2 licensee's second
processing round authorization;
(iii) The discontinuance of use of the spectrum assigned to the System
2 licensee under its second processing round authorization; or
(iv) The surrender of the System 2 licensee's second processing round
authorization to the Commission.
