Notification is the final phase of bringing a satellite system into use. It occurs only after the coordination phase is completed.
It involves establishing in the International Telecommunication Union's (ITU) Master International Frequency Register (the MIFR) a formal record of agreement between administrations about the satellite network. Once its details are permanently recorded there, other administrations are obligated to minimise interference to it by satellite and terrestrial networks for which they are responsible. This applies to new networks or for modifications to existing networks.
How does it work?
Notification is requested by an Administration on behalf of the operator of the network. Under Article 11 of the ITU Radio Regulations, an Administration must submit the coordination data to the ITU for examination. A full account of the notification procedure is provided in Articles 9 and 11 of the ITU Radio Regulations.
When it receives all of the data, the ITU examines it to see that coordination has been completed with all affected administrations. These include administrations that the ITU identified when it published the 'C' Notice and those that submitted disagreements in the four months after publication.
If the ITU Radiocommunication Bureau's findings are favourable, the frequency assignments are then recorded in the MIFR.
If not, they are published in a section of the IFIC (Part III - Unfavourable Findings) to advise administrations of the network's status. The notice is sent back to the originating Administration with the reasons for the finding and suggestions to solve the problem.
What is the timeframe?
Under Article 11 of the ITU Radio Regulations notification is required within seven years from the date of receipt of the API.
