Sentinel-1 Acquisition Segments

The KML files available on this page provide detailed information about the planned Sentinel-1 acquisitions.

See the archive for a full list of older KML files, dating back to April 2015.

Frequency and coverage of KML files

  • Each KML file usually covers a period of 20 days. The start and stop time of the planning information contained in the KML is defined in the KML file name.
  • Updated KML files will be provided in case of changes to the planning defined by a previously published KML file. In some cases, particularly when last minute changes are needed to accommodate requests from the Copernicus Emergency Management Service, the latest KML file may be shorter than a previous one, covering only a few days. An updated KML file of standard duration will usually be published one or two days later.
  • New KML files will be regularly provided to cover the next mission cycle/s
