Proposed updates to RALI MS 44

Consultation closes: 08 February 2019

IFC: 46/2018 space satellite

Consultation closed

After considering issues and suggestions raised in submissions, the ACMA has finalised updates to RALI MS 44.

A suggestion from submissions for different figures for notional Earth station antenna gain based on frequency range was adopted in the final version of RALI MS 44.

As a result of the finalisation of RALI MS 44, embargoes 49 and 72 have been revised. Specifically:

  • Embargo 72 has been modified to remove the bands covered in RALI MS 44, meaning embargo 72 is now only applicable to the frequency ranges 2025–2110 MHz and 22002290 MHz.
  • Similarly, the frequency ranges 3400–4200 MHz and 5850–6700 MHz have been removed from embargo 49 as coordination arrangements around the Mingenew site for these frequency ranges are covered in RALI MS 44.

The ACMA received four submissions to this consultation. These can be accessed from the right hand side index box under 'Other submissions received'.
