§  25.271   Control of transmitting stations.

   (a) The licensee of a facility licensed under this part is responsible
   for the proper operation and maintenance of the station.

   (b) The licensee of a transmitting earth station licensed under this
   part shall ensure that a trained operator is present on the earth
   station site, or at a designated remote control point for the earth
   station, at all times that transmissions are being conducted. No
   operator's license is required for a person to operate or perform
   maintenance on facilities authorized under this part.

   (c) Authority will be granted to operate a transmitting earth station
   by remote control only on the conditions that:

   (1) The parameters of the transmissions of the remote station monitored
   at the control point, and the operational functions of the remote earth
   stations that can be controlled by the operator at the control point,
   are sufficient to insure that the operations of the remote station(s)
   are at times in full compliance with the remote station
   authorization(s);

   (2) The earth station facilities are protected by appropriate security
   measures to prevent unauthorized entry or operations;

   (3) Upon detection by the license, or upon notification from the
   Commission of a deviation or upon notification by another licensee of
   harmful interference, the operation of the remote station shall be
   immediately suspended by the operator at the control point until the
   deviation or interference is corrected, except that transmissions
   concerning the immediate safety of life or property may be conducted
   for the duration of the emergency; and

   (4) The licensee shall have available at all times the technical
   personnel necessary to perform expeditiously the technical servicing
   and maintenance of the remote stations.

   (5) International VSAT system operators are required to maintain a
   control point within the United States, or to maintain a point of
   contact within the United States available 24 hours a day, 7 days a
   week, with the ability to shut off any earth station within the VSAT
   network immediately upon notification of harmful interference.

   (d) The licensee shall insure that the licensed facilities are properly
   secured against unauthorized access or use whenever an operator is not
   present at the transmitter.

   (e) The licensee of an NGSO FSS system operating in the 10.7-14.5 GHz
   bands shall maintain an electronic web site bulletin board to list the
   satellite ephemeris data, for each satellite in the constellation,
   using the North American Aerospace Defense Command (NORAD) two-line
   orbital element format. The orbital elements shall be updated at least
   once every three days.
