99th RRB meeting
99th RRB meeting
The Board considered in detail Document RRB25-2/6, from the Administration of Sweden, and Document RRB25-2/12, from the Administration of Luxembourg, regarding harmful interference to their respective satellite networks and services. The Board also noted Document RRB25-2/DELAYED/2, from the Administration of the Russian Federation, and Document RRB25-2/DELAYED/14, from the Administration of France, both for information. The Board noted the following points:
- The Administration of Sweden had continued to receive harmful interference to its FSS satellite services in the 13/14 GHz range that originated from the territory of the Russian Federation (Pionersky, Kaliningrad) and the Crimean Peninsula (Sevastopol) despite the many letters sent by the Administration of Sweden to ITU and the Administration of the Russian Federation, the Board’s requests in the matter and the bilateral meeting between the Administrations of the Russian Federation and Sweden on 13 March 2025.
- The Administration of Sweden had previously reported harmful interference to BSS feeder links in the 18 GHz range but no such harmful interference had been reported since the 98th Board meeting.
- The Administration of the Russian Federation had still not engaged in discussions with the Administration of Luxembourg despite several unfruitful attempts by the Bureau to organize a meeting.
- The Administration of the Russian Federation had investigated the cases reported but had identified no radio devices that might have caused harmful interference (content spoofing) to the BSS feeder links for the satellite networks SIRIUS-4-BSS, SIRIUS-5E-2, SIRIUS-5-BSS-2, SIRIUS-6-BSS, F-SAT-N3-21.5E, F-SAT-N-E-13E, F-SAT-N3-13E, F-SAT-N3-10E and EUTELSAT 3-10E in the 18 GHz range.
- According to the Administration of the Russian Federation, the interference to the receiving space stations of the satellite services of France, Sweden and Luxembourg in the 13/14 GHz range might be due to the use of military radio equipment.
- The Administration of the Russian Federation had invoked the issue of the peaceful use of the civilian space infrastructure of France, Sweden and Luxembourg and had set the resolution of that issue in United Nations bodies, other than ITU, as a pre-condition for its engagement in any further meetings with those administrations.
The Board expressed the view that compliance with treaty obligations under the ITU Constitution and Radio Regulations could not be conditioned on the resolution of an issue outside the scope of ITU. Consequently, the Board again strongly urged the Administration of the Russian Federation:
- to immediately cease any deliberate action to cause harmful interference to frequency assignments of other administrations;
- to continue investigating whether any earth station currently deployed at, or close to, the locations identified by geolocation measurements might have the capability to cause harmful interference in the 13/14 GHz frequency range, and to take the necessary actions in compliance with Article 45 of the ITU Constitution (“All stations, whatever their purpose, must be established and operated in such a manner as not to cause harmful interference to the radio services or communications of other Member States…”), so as to prevent the reoccurrence of such harmful interference;
- to provide information on the status of its investigation and actions carried out since the cases had been reported and prior to the 100th Board meeting.
The Board instructed the Bureau to:
- convene further meetings of the Administrations of the Russian Federation, France, Sweden and Luxembourg in the second half of 2025, so as to resolve the harmful interference cases reported by administrations and prevent their reoccurrence;
- invite all the administrations concerned to cooperate in goodwill to solve the cases of harmful interference;
- report on progress to the 100th Board meeting.
Furthermore, referring to its discussion of the case at its previous meetings, the Board decided to accede to the request of the Administrations of France and Sweden to publish the relevant information under resolves to instruct the Radio Regulations Board 2 of Resolution 119 (Rev. Bucharest 2022) of the Plenipotentiary Conference. The Board therefore instructed the Bureau to develop the relevant webpage for consideration at the next Board meeting.

98th RRB meeting
The Board considered in detail Addendum 5 to Document RRB25-1/8(Rev.1) from the Bureau, Documents RRB25-1/6 and RRB25-1/13 from the Administration of Sweden, Document RRB25-1/17 from co-signed administrations and Document RRB25-1/20 from the Administration of Luxembourg regarding harmful interference to satellite networks located at 5°E. The Board also noted Document RRB25-1/DELAYED/8 from the Administration of France for information. The Board noted the following:
- Discussions had been held between the Administration of the Russian Federation and the Administration of Sweden as well as between the Administration of the Russian Federation and the Administration of France on 13 and 14 March 2025, respectively.
- However, new reports from the Administrations of Sweden, France and Luxembourg indicated that harmful interference continued to be present, with geolocation measurements indicating that they had originated from the territory of the Russian Federation as well as the Crimean Peninsula.
- The Administration of the Russian Federation had investigated the cases reported but had found no interference present when the investigation had been carried out.
- The Administration of the Russian Federation had still not provided the information that the Board had requested at its 96th meeting.
The Board also noted:
- the two separate reports of geolocation measurements from the international space radio monitoring station, part of the International Monitoring System, based in Leeheim (Germany), reconfirming that the sources of harmful interference were located on the territory of the Russian Federation as well as the Crimean Peninsula;
- that, based on monitoring reports, there were no disputes regarding the harmful interference sources; therefore, there was no need to request further geolocation measurements from the International Monitoring System.
Consequently, the Board again reiterated its requests to the Administration of the Russian Federation:
- to immediately cease any deliberate action to cause harmful interference to frequency assignments of other administrations;
- to provide information on the status of its investigation and actions carried out since the cases had been reported and prior to the 99th Board meeting;
- to further investigate whether any earth stations currently deployed at, or close to, the locations identified by geolocation measurements might have the capability to cause harmful interference in the 13/14 GHz and 18 GHz frequency ranges, and to take the necessary actions in compliance with Article 45 of the ITU Constitution (“All stations, whatever their purpose, must be established and operated in such a manner as not to cause harmful interference to the radio services or communications of other Member States…”), so as to prevent the reoccurrence of such harmful interference.
The Board again urged the Administrations of Sweden, the Russian Federation, Luxembourg and co-signed administrations, in compliance with RR No. 15.22, to collaborate and exercise the utmost goodwill and mutual assistance in the resolution of the harmful interference cases.
The Board instructed the Bureau to:
- convene further meetings of the Administrations of the Russian Federation, France, Sweden and Luxembourg in the first half of 2025, to resolve the harmful interference cases reported by administrations and prevent them from reoccurring;
- report on progress to the 99th Board meeting.
The Board decided that it was still premature at that stage to accede to the requests under resolves to instruct the Radio Regulations Board 2 of Resolution 119 (Rev. Bucharest, 2022) of the Plenipotentiary Conference; but, in the absence of the requested information, the Board would reconsider that decision at its 99th meeting.
