Agenda Item Description
Agenda Item 1.17

This agenda item is to consider regulatory provisions for receive-only space weather sensors and their protection in the Radio Regulations, taking into account the results of ITU Radiocommunication Sector studies, in accordance with Resolution 682. The ITU-R is invited to:

  1. study spectrum needs and appropriate protection criteria for receive-only space weather sensors, as well as system characteristics, as appropriate
  2. sharing and compatibility studies pertaining to potential new primary allocations to MetAids (space weather) in the frequency bands 27.5 - 28.0 MHz, 29.7 - 30.2 MHz, 32.3 - 32.6 MHz, 37.5 - 38.325 MHz, 73.0 - 74.6 MHz and 608 - 614 MHz for receive only sensors
  3. study possible regulatory provisions in the Radio Regulations to accommodate the possibility for an administration that desires to notify a receive-only space weather sensor station to be included in the MIFR

Any possible new primary MetAids (space weather) allocations shall not claim protection from, nor constrain the future development of, incumbent services in these frequency bands or adjacent frequency bands

WRC-23 is invited to review the results of these studies and take necessary actions, as appropriate
Agenda Item 1.18

This agenda item is to consider, based on the results of ITU Radiocommunication Sector studies, possible regulatory measures regarding the protection of the Earth exploration-satellite service (passive) and the radio astronomy service in certain frequency bands above 76 GHz from unwanted emissions of active services, in accordance with Resolution 712. The ITU-R is invited to:

1. study compatibility between the EESS(passive) and the corresponding active services in adjacent bands as listed below:

  • EESS(passive) in 86-92 GHz, active services in 81-86 GHz (FSS UL, MS) and 92-94 GHz (MS, RLS)
  • EESS(passive) in 114.25-116 GHz, active services in 111.8-114.25 GHz (FS, MS)
  • EESS(passive) in 164-167 GHz, active services in 158.5-164 GHz (FS, FSS DL, MS, MSS DL) and 167-174.5 GHz (FS, FSS DL, ISS, MS)
  • EESS(passive) in 200-209 GHz, active service in 191.8-200 GHz (FS, ISS, MS, MSS, RNS, RNSS) and in 209-217 GHz (FS, FSS UL, MS)

2. study compatibility between the RAS and the corresponding active services in adjacent bands as listed below:

  • RAS in 76-81 GHz, active services in 71-76 GHz (FSS, MSS, BSS)
  • RAS in 130-134 GHz, active services in 123-130 GHz (FSS, MSS, RNSS)
  • RAS in 164-167 GHz, active services in 167-174.5 GHz (FSS)
  • RAS in 226-231.5 GHz, active service in 232-235 GHz (FSS)

WRC-27 is invited to determine, based on the results of studies, any required regulatory measures regarding the protection of the EESS(passive) and RAS for the frequency bands listed above.
Agenda Item 1.19

This agenda item is to consider possible primary allocations in all Regions to the Earth exploration-satellite service (passive) in the frequency bands 4 200 - 4 400 MHz and 8 400 - 8 500 MHz without protection from existing services in these frequency bands and in adjacent bands.
