Mon, 31 May - Fri, 4 Jun 2021

The European Space Agency is organising the 11th International Workshop on “Advances in the Science and Applications of SAR Interferometry and Sentinel-1 InSAR”, Fringe 2021.


Fringe 2021 is organised around:

  • Papers and e-posters selected by the Scientific Committee;
  • Invited papers on ESA-funded studies and Sentinel-1 and future ESA SAR mission status reports;
  • Round-table discussions with seed questions prepared by the session chairpersons and ESA.

The event will take place from 31 May - June 4 2021. No participation fees will be charged.


  • To bring together the global InSAR research and development communities and facilitate international exchange between researchers and research groups; 
  • To present the Sentinel-1 mission status, algorithms and products;
  • To review and assess the progress according to the recommendations voiced at FRINGE 2017;
  • To consult the scientific communities to prepare ESA for starting supporting science activities for Sentinel-1 and BIOMASSin the InSAR domain.

Technical areas:

  • Atmosphere, Ionosphere & InSAR Meteorology
