Sec. 25.135 Licensing provisions for earth station networks in the non-
voice, non-geostationary mobile-satellite service.
(a) Each applicant for a blanket earth station license in the non-
voice, non-geostationary mobile-satellite service shall demonstrate that
transceiver operations will not cause unacceptable interference to other
authorized users of the spectrum, based on existing system information
publicly available at the Commission at the time of filing, and will
comply with operational conditions placed upon the systems with which
they are to operate in accordance with Sec. 25.142(b). This
demonstration shall include a showing as to all the technical
parameters, including duty cycle and power limits, under which the
individual user transceivers will operate.
(b) Transceiver units associated with the non-voice, non-
geostationary mobile-satellite service may not be operated on civil
aircraft. All portable or hand-held transceiver units (including
transceiver units installed in other devices that are themselves
portable or hand-held) having a receiver operating in the 137-138 MHz
band shall bear the following statement in a conspicuous location on the
device: ``This device may not be operated while on board a civil
aircraft. It must be turned off at all times while on board such an
aircraft.'' This subsection shall not apply to transceiver units whose
receivers are incapable of radiating in the 108-137 MHz frequency bands.
(c) Transceiver units in this service are authorized to communicate
with and through U.S. authorized space stations only. No person shall
transmit to a space station unless the specific transmission is first
authorized by the space station licensee or by a service vendor
authorized by that licensee.
(d) Any transceiver unit associated with this service will be
deemed, when communicating with a particular non-voice, non-
geostationary mobile-satellite service system pursuant to paragraph (c)
of this section, to be temporarily associated with and licensed to the
system operator or service vendor holding the blanket earth station
license awarded pursuant to Sec. 25.115(d). The domestic earth station
licensee shall, for such temporary period, assume the same licensee
responsibility for such transceiver as if such transceiver were
regularly licensed to it.
