§ 25.143 Licensing provisions for the 1.6/2.4 GHz Mobile-Satellite Service
and 2 GHz Mobile-Satellite Service.
(a) System license. Applicants authorized to construct and launch a
system of technically identical satellites will be awarded a single
"blanket" license. In the case of non-geostationary satellites, the
blanket license will cover a specified number of space stations to
operate in a specified number of orbital planes. In the case of
geostationary satellites, as part of a geostationary-only satellite
system or a geostationary/non-geostationary hybrid satellite system, an
individual license will be issued for each satellite to be located at a
geostationary orbital location.
(b) Qualification Requirements--(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
letter of intent filer shall 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 70DEG North latitude and as far south as
55DEG 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 5DEG 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 5DEG 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) Replacement of Space Stations Within the System License Term.
Licensees of 1.6/2.4 GHz mobile-satellite systems authorized through a
blanket license pursuant to paragraph (a) of this section 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:
(1) The licensee intends to launch a space station that is technically
identical to those authorized in its system authorization, and
(2) Launch of this space station will not cause the licensee to exceed
the total number of operating space stations authorized by the
(f) 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.
(h) 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.
