Region of interest (ROI)

The Sentinel products cover a ROI over Australasia, South-East Asia, the South Pacific, the Indian Ocean and the Australian Antarctic Territory, as depicted in the map below.

Product capture and management

The Hub’s product capture and management regimes are given in the table below.

Mission - status / *acquisition plansProduct Region of capture and management regime by the Hub
Sentinel-1A - operational [3 July 2014 - present]
Sentinel-1B - operational [25 July 2016 - present]

*The Sentinel-1 acquisition segments with the related mode and polarisation are defined on a 12-day cycle. The high-level operations plan can be found in the observation scenarios. The Sentinel-1 ground segment production baseline is described in the production scenario .
RAW – Full Resolution
GRD – Full Resolution
GRD – High resolution
GRD – Medium Resolution

We aim to make 90 percent of these products available in Australia within 24 hours of it appearing in the European hubs. Successful data replication, completeness and consistency with the European hubs are checked routinely and cleaned monthly.

For more information about latency and completeness of the Hub data, see the reporting dashboard.

Adding new products

As new Sentinel missions are launched, new products are added to the Hub based on the needs of its users, which currently includes:

  • government partners that finance its operation
  • industry
  • the research sector
  • academia
  • non-government sectors across our region

For technical information about the Sentinel satellite missions, see Sentinel Online.
