Agenda Item Description
Agenda Item 1.15

This agenda item is consider studies on frequency-related matters, including possible new or modified space research service (space-to-space) allocations, for future development of communications on the lunar surface and between lunar orbit and the lunar surface. The ITU-R is invited to:

  1. study the spectrum needs of systems in the SRS which may operate on the lunar surface or systems in lunar orbit communicating with systems on the lunar surface, in the frequency ranges:
    • 390 - 406.1 MHz, 420 - 430 MHz and 440 - 450 MHz outside the shielded zone of the Moon (SZM)
    • 2 400 - 2 690 MHz, 3 500 - 3 800 MHz, 5 150 - 5 725 MHz, 5 775 - 5 925 MHz, 7 190 - 7 235 MHz, 8 450 - 8 500 MHz and 25.25 - 28.35 GHz
  2. study the technical and operational characteristics as well as protection criteria of systems in the SRS that are planned for operation in the frequency bands above as well as protection criteria to be applied for the protection of the radio astronomy service (RAS) and SRS active and passive sensors on the lunar surface and in lunar orbit
  3. study the propagation considerations for lunar surface systems and lunar-orbiting systems operating in the frequencies above
  4. study sharing and compatibility related to systems in the SRS that are planned for operation in the frequency ranges above to ensure protection of radiocommunication services in these bands (SRS, FSS, BSS, ISS, EESS, ISM, fixed, mobile etc.) and in particular the RAS
  5. study potential new or modified frequency allocations and/or identifications to the SRS with appropriate regulatory provisions, for communications on the lunar surface or in lunar orbit communicating with systems on the lunar surface
  6. to study spectrum needs for lunar communications which may be needed for communications between the Earth, lunar-orbiting spacecraft and the lunar surface
  7. to study whether future radiocommunication systems in the vicinity of the Moon can be accommodated within existing SRS and whether the regulatory provisions described in the Radio Regulations are sufficient

With the exception of the last item, WRC-27 is invited to review the results of these studies and take necessary actions, as appropriate
