CRAF, representing the European Radio Astronomy observatories, participated in the Working Party 7D meeting organized by the ITU Radiocommunication Sector and held virtually from 12 to 16 April. WP7D covers the radio astronomy service studies at ITU. Its scope includes radio astronomy and radar astronomy sensors, both Earth-based and space-based, including space very long baseline interferometry (VLBI).
The meeting discussed the progress made on the various agenda items of the next World Radiocommunication Conference 2023 (WRC23) related to the radio astronomy service. CRAF contributions focused on the agenda items of mobile services, UHF review in region 1, and the protection of receive-only space weather sensors. CRAF also continued coordination during the meeting on the new questions for the recognition of the VLBI global Observing System (VGOS) services by ITU.
