The objective of the regular monitoring program in frequency bands between 2 850 kHz and 28 000 kHz is to:
- identify whose emissions are not in compliance with the Radio Regulations (RR);
- provide administrations that do not have monitoring facilities with information for frequency management purposes and to comply with No.3.14 of the RR;
- assemble information on spectrum utilization at the location of the monitoring stations and to derive thereafter how the spectrum is used;
- collect information, when required by Radiocommunication conference, on the use of the bands exclusively allocated to specific services (i.e. broadcasting, maritime, aeronautical) for consideration by the appropriate Radiocommunication Conferences
Monitoring stations participating in the International Monitoring System (IMS) send their reports to the Bureau via their designated centralizing office and in accordance with Article 16 of the RR, the Bureau records and publish periodically the summaries of monitoring information.
The monitoring reports should follow a specific electronic data format, as defined in BR Circular Letter CR/159 (dated 9 May 2001) and they should be sent to the Bureau by email to
