Sec. 25.111  Additional information.

    (a) The Commission may request from any party at any time additional 
information concerning any application, or any other submission or 
pleading regarding an application, filed under this part.
    (b) Applicants, permittees and licensees of radio stations governed 
by this part shall provide the Commission with all information it 
requires for the Advance Publication, coordination and notification of 
frequency assignments pursuant to the international Radio Regulations 
and consultations required by Article XIV of the INTELSAT Agreement and 
Article 8 of the INMARSAT Convention. This information includes, but is 
not limited to, that specified in appendices 3 and 4 of the Radio 
Regulations (Geneva 1979). No protection from interference caused by 
radio stations authorized by other Administrations is guaranteed unless 
coordination procedures are timely completed or, with respect to 
individual administrations, by successfully completing coordination 
agreements. Any radio station authorization for which coordination has 
not been completed may be subject to additional terms and conditions as 
required to effect coordination of the frequency assignments with other 
Administrations.
