The resolution of harmful interferences resulting from emissions of satellite systems, in most cases, requires a solution by means of co-operation between the Administrations and the satellite operators. So as to meet the need to develop measures regionally for the treatment of harmful interferences resulting from unauthorized emissions of satellite systems in the Americas, the Permanent Consultative Committee II: Radiocommunications including Broadcasting approved the following mechanisms to resolve cases of harmful interference among satellite systems:

1. To facilitate the resolution of cases of harmful interference in the region of the Americas that cannot be resolved at the operator level, for example from unauthorized transmissions to satellite communication systems, it is essential that the affected satellite operator work in cooperation with the licensing Administration of the space station affected by the interference.

2. If a case of harmful interference so justifies, the satellite operator whose service is being interfered with (the “Victim Operator”) shall inform the licensing Administration, giving all possible information which will assist the Administration in determining the source of the interference.

  • Full particulars relating to harmful interference (i.e. frequency, bandwidth, power density, location, time, etc.) shall be provided by the victim satellite operator taking into account the harmful interference location identified in accordance with the Annex of Resolution PCC.II/RES.35 (VIII-06) and relevant procedures of the ITU Radio Regulations.

3. The licensing Administration of the affected space station (the “Victim Administration”) shall inform the Administration having jurisdiction over the suspected transmitting earth station interferer (the “Interferer Administration”), giving all available information which will assist in determining the interference source.

4. In cases of harmful interference where rapid action is required, communications between the Victim and Interferer Administrations shall be transmitted by electronic means. The Interferer Administration shall acknowledge receipt of the information from the Victim Administration. Such acknowledgment shall not constitute an acceptance of responsibility.

5. An Administration receiving a communication to the effect that a station located within its territory is suspected to be the source of harmful interference shall promptly investigate the matter on the basis of information received and respond to the Victim Administration as soon as possible and preferably within 30 days to indicate the results of its investigation and, if applicable, the steps which have been, or will be, taken to eliminate the harmful interference.

  • If further observations and measurements are necessary to determine the source of, and to establish the responsibility for, the harmful interference, the Victim and Interferer Administrations shall cooperate to facilitate the detection and elimination of the harmful interference.

6. The Victim Operator shall report to the licensing Administration as to the outcome of the steps taken to eliminate the harmful interference.

  • If the harmful interference persists in spite of the steps taken by the Interferer Administration, the Victim Administration:

a) may address to the Interferer Administration a report of irregularity or infraction in accordance with the provisions of Section V of Article 15 of the ITU Radio Regulations;

b) shall forward details of the case to the ITU Radiocommunication Bureau for its information and request the Bureau to act in accordance with the provisions of Section I of Article 13 of the ITU Radio Regulations. The Interferer Administration shall be copied on all correspondence between the Victim Administration and the Bureau.
