Throughout the ITU‑R WRC-23 preparatory work the IARU has maintained its position that the regulatory status of the amateur and amateur satellite services in this range is already clear. Therefore any developments to add new regulatory, operational or technical measures to be incorporated as new mandatory elements into the Radio Regulations are opposed. The final position can be found here.

ITU‑R Working Party 4C meeting #30 could not agree on the technical and operational measures required to ensure the protection of the RNSS (radio navigation satellite service) in the amateur 23cm band. (Relating to WRC-23 AI 9.1b).

Working Party 4C met over the period 21^st to 27^th June 2023 and discussed several contributions relating to the draft Recommendation ITU‑R M.[AS_GUIDANCE] under development in WP5A . The group struggled to find consensus amongst the RNSS community on the measures it could propose to WP5A.

However the working party did accept a contribution from the IARU presenting a Monte Carlo style studythat shows the low percentage of RNSS receivers located around an amateur transmitter that are likely to be in a position to suffer interference. The study will be incorporated as a revision to the ITU‑R Report M.2513.

The IARU report from the WP4C meeting can be downloaded here.

The outcome of the discussion and final elements of the ITU‑R Recommendation remain uncertain and work on this topic will continue at the next ITU‑R WP5A meeting in September with some urgency to finalise ahead of the WRC.

At the last CEPT CPG meeting #8 during May, the CEPT put its weight behind the development of a European Common Proposal (ECP) that would in effect mandate the technical and operational guidance under development in ITU‑R WP5A to allow the amateur and amateur satellite services to continue to operate and avoid interference to the RNSS.

A summary report from the CPG meeting #8 can be found here.

The IARU is supporting the development of an ITU‑R Recommendation to identify the technical and operational constraints that might be required by the amateur and amateur satellite services in the 23cm band. However, the IARU continues to assert that WRC23 does not need to make any changes to the Radio Regulations for this Recommendation under development in WP5A to be effective.
