ITU‑R Working Party 5A is making progress on the 23cm amateu
Inviato: 25 novembre 2022, 18:45ITU‑R Working Party 5A is making progress on the 23cm amateur band and RNSS (radio navigation satellite service) coexistence.
Nov 25, 2022 - Spectrum - Barry, G4SJH
Over the period 14th to 25th November 2022, the preparatory work for WRC-23 agenda item 9.1b continued in ITU‑R Working Party 5A (WP5A). Two deliverables are under discussion:
1) Draft ITU‑R Report M.[AMATEUR_CHARACTERISTICS] – this reports on the specific 23cm band amateur and amateur satellite service technical parameters and operational characteristics used in the studies now published in ITU‑R Report M.2513 – 0.
2) Draft ITU.R Recommendation M.[AS_GUIDANCE] – this will recommend guidance that national administrations can take to facilitate the protection of the radio navigation satellite service from harmful interference from amateur radio stations.
Since the previous WP5A meeting the IARU global WRC23 9.1b team led by G4SJH has been consulting with the amateur community resulting in a contribution to the draft guidance recommendation. As usual, the IARU participated in the meeting to support the contribution and take part in the ongoing discussion and negotiations. Contributions were also provided by a number of national administrations and a summary report of the meeting can be downloaded https://www.iaru.org/wp-content/uploads/2022/11/Report-from-WP5A_Nov-2022.pdf
In general the development of the recommendation is moving in a suitable direction and many of the IARU proposals remain in the draft document that will go forward to the next meeting for further work.
Meanwhile in CEPT the work in project team SE40 continues with their development of an ECC Report on the same coexistence problem and also met during November (3 – 4th).
The work on this topic will continue throughout next year both in ITU‑R and in the regional telecommunications organisations and the IARU is committed to ensure the studies are properly interpreted and that due account is taken of the realities of amateur operations in this band.
