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 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.
