§ 25.272   General inter-system coordination procedures.

   (a)  Each  space station licensee in the Fixed-Satellite Service shall
   establish  a  satellite  network  control  center  which will have the
   responsibility to do the following:

   (1) Monitor space-to-Earth transmissions in its system (thus indirectly
   monitoring uplink earth station transmissions in its system) and

   (2) Coordinate transmissions in its satellite system with those of other
   systems to prevent harmful interference incidents or, in the event of a
   harmful interference incident, to identify the source of the interference
   and correct the problem promptly.

   (b) [Reserved]

   (c) The transmitting earth station licensee shall provide the operator(s) of
   the satellites, on which the licensee is authorized to transmit, contact
   telephone numbers for the control center of the earth station and emergency
   telephone numbers for key personnel; a current file of these contacts shall
   be maintained at each satellite system control center.

   (d) An earth station licensee shall ensure that each of its authorized earth
   stations complies with the following:

   (1) The earth station licensee shall ensure that there is continuously
   available means of communications between the satellite network control
   center  and  the earth station operator or its remote control point as
   designated by the licensee.

   (2) The earth station operator shall notify the satellite network control
   center and receive permission from the control center before transmitting to
   the satellite or changing the basic characteristics of a transmission.

   (3)  The  earth station operator shall keep the space station licensee
   informed of all actual and planned usage.

   (4) Upon approval of the satellite network control center, the earth station
   operator may radiate an RF carrier into the designated transponder. Should
   improper illumination of the transponder or undue adjacent transponder
   interference be observed by the satellite network control center, the earth
   station operator shall immediately take whatever measures are needed to
   eliminate the problem.

   (5) The space station licensee may delegate the responsibility and duties of
   the satellite network control center to a technically qualified user or
   group of users, but the space station licensee shall remain ultimately
   responsible for the performance of those duties.
