Technical documentation

This page presents relevant documentation for end-user to properly manipulate the Sentinel-1 products.

 

Generic Sentinel-1 technical documentation

The documentation of Sentinel-1 products can be found in Sentinel online in the Sentinel-1 SAR document library HERE

This contains documentation on the Level 0 products:

• The Sentinel-1 SAR Space Packet Protocol Data Unit: specification of Sentinel-1 Level 0 product format

This contains as well documentation on the specification of the Level 1 and Level 2 products:

• The Sentinel-1 product definition document: definition of targeted Sentinel-1 product performances
• The Sentinel-1 product specification: specification of Sentinel-1 Level 1 and Level 2 product format
• The Sentinel-1 auxiliary product specification: specification of Sentinel-1 auxiliary products for both Level 1 and Level 2 processor
• The Sentinel-1 Level 1 Detailed Processing Model
• The Sentinel-1 Level 2 Algorithm Theoretical Baseline Document for the three components OWI/OSW/RVL
• The Algorithm Theoretical Baseline Document explaining how the AUX_SCS (Simulated Cross Spectra) is computed

This contains as well documentation on the Extended Timing Annotation Dataset (ETAD) processor and its products:

• The Sentinel-1 ETAD ATBD: documentation of the algorithms applied in the ETAD processor
• The Sentinel-1 ETAD product definition
• The Sentinel-1 ETAD product specification
• The Sentinel-1 ETAD Auxiliary product specification
