List VIII is a necessary document for operating in the International Monitoring System (IMS).
It contains information, submitted by Administrations, about the different functions that each monitoring station is able to perform, both in the terrestrial and in the space radiocommunication services.
In cases of Harmful Interference (HI), where rapid action is required, information may be exchanged directly between stations of the IMS.
It is essential that those administrations already having terrestrial and/or space monitoring facilities, which participate in the IMS, notify the Radiocommunication Bureau (BR) of the particulars of their monitoring stations for inclusion into this List.
