Agenda Item Description
Agenda Item 1.14

This agenda item is to review and consider possible adjustments of the existing or possible new primary frequency allocations to EESS (passive) in the frequency range 231.5 - 252 GHz to ensure alignment with more up-to-date remote-sensing observation requirements. The ITU-R is invited to:

  1. to review the existing primary allocations to the EESS (passive) in the frequency range 231.5 - 252 GHz in order to analyse if these allocations are aligned with observation requirements of passive microwave sensors
  2. to study the impact that any changes to the EESS (passive) allocations in the frequency range 231.5 - 252 GHz might have on other primary services in these frequency bands
  3. to study, as appropriate, possible adjustments to the EESS (passive) allocations in the frequency range 231.5 - 252 GHz, taking into account the results of studies

WRC-23 is invited to review the results of these studies with a view to adjusting existing allocations or adding possible new allocations, as appropriate, to the EESS (passive) in the frequency range 231.5 - 252 GHz without unduly constraining the other primary services currently allocated in this frequency range

Agenda Item 9.1.1

This agenda item is to review the results of studies relating to the technical and operational characteristics, spectrum requirements and appropriate radio service designations for space weather sensors with a view to describing appropriate recognition and protection in the Radio Regulations without placing additional constraints on existing services.

The ITU-R is invited to:

  1. to identify, in time for WRC-23, and based upon existing and possible further ITU-R studies on the technical and operational characteristics, specific space weather sensors which need to be protected by appropriate regulation. This includes determining if receive-only space weather sensors shall be designated as applications of the Metaids services, to determine the appropriate radiocommunication service, if any, for cases where it is determined that receive-only space weather sensors do not fall under the Metaids service
  2. to conduct, in time for WRC-23, any necessary sharing studies with incumbent systems operating in frequency bands used by space weather sensors with the objective of determine potential regulatory provisions that can be provided to receive-only operational space weather sensors for their appropriate recognition in the Radio Regulations, while not placing additional constraints on incumbent services
  3. to develop potential solutions to describe in the Radio Regulations in Articles 1 and 4 and/or as a WRC resolution, if deemed appropriate, for consideration by WRC-23, space weather sensor systems and their corresponding usage, as well as protection requirements for receive-only space weather sensors
  4. to conduct studies, in time for WRC-23, on the technical and operational characteristics of active space weather sensors and conduct necessary sharing studies with incumbent systems operating in frequency bands used by active space weather sensors, with the objective of determining the appropriate radiocommunication service for those sensors

The Director of the BR is instructed to report on the results of the ITU-R studies to WRC-23
