Sec. 25.273  Duties regarding space communications transmissions.

    (a) No person shall:
    (1) Transmit to a satellite unless the specific transmission is 
first authorized by the satellite network control center;
    (2) Conduct transmissions over a transponder unless the operator is 
authorized by the satellite licensee or the satellite licensee's 
successor in interest to transmit at that time; or
    (3) Transmit in any manner that causes unacceptable interference to 
the authorized transmission of another licensee.
    (b) Satellite operators shall provide upon request by the Commission 
and by earth station licensees authorized to transmit on their 
satellites relevant information needed to avoid unacceptable 
interference to other users, including the polarization angles for 
proper illumination of a given transponder.
    (c) Space station licensees are responsible for maintaining complete 
and accurate technical details of current and planned transmissions over 
their satellites, and shall require that authorized users of 
transponders on their satellites, whether by tariff or contract, provide 
any necessary technical information in this regard including that 
required by Sec. 25.272. Based on this information, space station 
licensees shall exchange among themselves general technical information 
concerning current and planned transmission parameters as needed to 
identify and promptly resolve any potential cases of unacceptable 
interference between their satellite systems.
    (d) Space stations authorized after May 10, 1993 which do not 
satisfy the requirements of Sec. 25.210 may be required to accept 
greater constraints in resolving interference problems than complying 
ones. The extent of these constraints shall be determined on a case-by-
case basis.
