§ 25.143 Licensing provisions for the 1.6/2.4 GHz Mobile-Satellite Service
and 2 GHz Mobile-Satellite Service.
(a) Authority to launch and operate a constellation of NGSO satellites
will be granted in a single blanket license for operation of a
specified number of space stations in specified orbital planes. An
individual license will be issued for each GSO satellite, whether it is
to be operated in a GSO-only system or in a GSO/NGSO hybrid system.
(b) Qualification Requirementsâ€”(1) General Requirements. Each
application for a space station system authorization in the 1.6/2.4 GHz
Mobile-Satellite Service or 2 GHz Mobile-Satellite Service must include
the information specified in § 25.114. Applications for
non-U.S.-licensed systems must comply with the provisions of § 25.137.
(2) Technical qualifications. In addition to providing the information
specified in paragraph (b)(1) of this section, each applicant and
petitioner must demonstrate the following:
(i) That a proposed system in the 1.6/2.4 GHz MSS frequency bands
employs a non-geostationary constellation or constellations of
(ii) That a system proposed to operate using non-geostationary
satellites be capable of providing Mobile-Satellite Service to all
locations as far north as 70Â° North latitude and as far south as 55Â°
South latitude for at least 75% of every 24-hour period, i.e., that at
least one satellite will be visible above the horizon at an elevation
angle of at least 5Â° for at least 18 hours each day within the
described geographic area;
(iii) That a system proposed to operate using non-geostationary
satellites be capable of providing Mobile-Satellite Service on a
continuous basis throughout the fifty states, Puerto Rico and the U.S.
Virgin Islands, i.e., that at least one satellite will be visible above
the horizon at an elevation angle of at least 5Â° at all times within
the described geographic areas; and
(iv) That a system only using geostationary orbit satellites, at a
minimum, be capable of providing Mobile-Satellite Service on a
continuous basis throughout the 50 states, Puerto Rico, and the U.S.
Virgin Islands, if technically feasible.
(v) That operations will not cause unacceptable interference to other
authorized users of the spectrum. In particular, each application in
the 1.6/2.4 GHz frequency bands shall demonstrate that the space
station(s) comply with the requirements specified in § 25.213.
(c) Safety and distress communications. (1) Stations operating in the
1.6/2.4 GHz Mobile-Satellite Service and 2 GHz Mobile-Satellite Service
that are voluntarily installed on a U.S. ship or are used to comply
with any statute or regulatory equipment carriage requirements may also
be subject to the requirements of sections 321(b) and 359 of the
Communications Act of 1934. Licensees are advised that these provisions
give priority to radio communications or signals relating to ships in
distress and prohibits a charge for the transmission of maritime
distress calls and related traffic.
(2) Licensees offering distress and safety services should coordinate
with the appropriate search and rescue organizations responsible for
the licensees service area.
(d) Prohibition of certain agreements. No license shall be granted to
any applicant for a space station in the Mobile-Satellite Service
operating at 1610-1626.5 MHz/2483.5-2500 MHz if that applicant, or any
persons or 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 possession, to construct or
operate space segment or earth stations, 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.
