Draft: Business operating procedure—Interim arrangements for the submission and processing of applications for space and space receive apparatus licences authorising the use of earth stations in motion in the fixed-satellite service communicating with:

  • Non-geostationary space stations in the frequency ranges 17.7−18.2 GHz, 18.8−19.3 GHz, 19.7−20.2 GHz, 28.5−29.1 GHz and 29.5−30 GHz
  • Geostationary space stations in the frequency ranges 17.7−18.2 GHz, 18.8−19.3 GHz and 28.5−29.1 GHz

Executive summary

Earth stations in the fixed satellite service (as the name suggests) are intended to be at fixed locations on land. Spectrum planning, coordination and regulatory arrangements for the fixed satellite service are designed on the principle that earth stations are at a fixed location.

To provide additional capacity and opportunities in satellite-delivered telecommunication services, there is a growing trend for fixed satellite systems to use what are known as earth stations in motion (ESIMs) for ubiquitous user terminals. ESIMs are earth stations that are in motion on land, on water or in the air. Typically, such systems employ techniques to ensure the earth station antenna is always pointed at the associated satellite, with a high degree of accuracy and reliability, even though the earth station is moving. Thus, ESIMs have a similar level of performance to that of an earth station at a fixed point.  

The ACMA already provides support for ubiquitous ESIMs communicating with geostationary space stations in the fixed-satellite service in the frequency bands 19.7−20.2 GHz and 29.5−30.0 GHz in accordance with ITU Resolution 156 (WRC-15). These arrangements are contained in the ACMA’s Draft Business operating procedure (BOP): Submission and processing of applications for licences authorising the use of earth stations in motion (ESIMs) communicating with geostationary space stations in the fixed-satellite service in the frequency bands 19.7−20.2 GHz and 29.5−30.0 GHz (see Downloads box, above).  

Based on requests from industry, the ACMA is proposing to implement arrangements to support ubiquitous ESIMs communicating with:

  • geostationary (GSO) space stations in the fixed-satellite service with earth stations in motion on land, on water or in the air in the frequency ranges 17.7−18.2 GHz (space-to-Earth), 18.8−19.3 GHz (space-to-Earth) and 28.5−29.1 GHz (Earth-to-space)
  • non-geostationary (NGSO) space stations in the fixed-satellite service with earth stations in motion on land or on water in the frequency ranges 17.7−18.2 GHz (space-to-Earth), 18.8−19.3 GHz (space-to-Earth), 19.7−20.2 GHz (space-to-Earth), 28.5−29.1 GHz (Earth-to-space) and 29.5−30 GHz (Earth-to-space).

With the World Radiocommunications Conference 2019 (WRC-19) also considering earth stations in motion, the proposed arrangements are interim and will be reviewed after WRC‑19.

Issues for comment

Issue 1

The ACMA invites comment on a proposed decision under section 10(10) of the Spectrum Plan to enable the use of:

  • earth station transmitters in motion on land or on water communicating with NGSO space stations in the fixed-satellite service (Earth-to-space) in the frequency ranges 28.5–29.1 GHz and 29.5–30 GHz
  • earth station transmitters in motion on land, on water or in the air communicating with GSO space stations in the fixed-satellite service (Earth-to-space) in the frequency range 28.5–29.1 GHz.
Issue 2

The ACMA is also inviting comment on a proposed interim BOP (including assessment criteria and relevant special conditions) to be followed when seeking the issue of space or space receive licences authorising the use of ubiquitous ESIMs communicating with:

  • GSO space stations in the fixed-satellite service with earth stations in motion on land, on water or in the air in the frequency ranges 17.7−18.2 GHz (space-to-Earth), 18.8−19.3 GHz (space-to-Earth) and 28.5−29.1 GHz (Earth-to-space)
  • NGSO space stations in the fixed-satellite service with earth stations in motion on land or on water in the frequency ranges 17.7−18.2 GHz (space-to-Earth), 18.8−19.3 GHz (space-to-Earth), 19.7−20.2 GHz (space-to-Earth), 28.5−29.1 GHz (Earth-to-space) and 29.5−30 GHz (Earth-to-space).
