  §  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 § 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 without
   an FCC license for such operation may transmit to a space station in
   this service from anywhere in the United States except to receive
   service from the holder of a pertinent FCC blanket license or from
   another party with the permission of such a blanket licensee.

   (d) The holder of an FCC blanket license for operation of transceivers
   for communication via a non-voice, non-geostationary mobile-satellite
   system shall be responsible for operation of any such transceiver to
   receive service provided by the blanket licensee or provided by another
   party with the blanket licensee's consent. Operators of non-voice,
   non-geostationary mobile-satellite systems shall not transmit
   communications to or from user transceivers in the United States unless
   such communications are authorized under a service contract with the
   holder of a pertinent FCC blanket license or under a service contract
   another party with authority for such transceiver operation delegated
   by such a blanket licensee.
