Sentinel-1C Level 0 Product

The Sentinel-1C satellite was launched December 5, 2024. Sentinel-1C is the the latest satellite to be added to the Sentinel-1 constellation. The Sentinel-1 satellites (Sentinel-1A, Sentinel-1B, and Sentinel-1C) are sun-synchronous polar-orbiting satellites that operate day and night performing C-band synthetic aperture radar (SAR) imaging. The Sentinel-1 satellites operate in four imaging modes with different resolutions (down to 5 meters) and coverage (up to 400 kilometers). The Sentinel-1 satellites provide dual polarization capability and short revisit times.

Sentinel-1C Level 0 products consist of compressed and unprocessed instrument source packets, with additional annotations and auxiliary information to support processing. Level 0 products are the basis from which all other high level products are produced. They are compressed using Flexible Dynamic Block Adaptive Quantization (FDBAQ) which provides a variable bit rate coding that increases the number of bits allocated to bright scatterers. For the data to be usable, it will need to be decompressed and processed using focusing software.

Level 0 data includes noise, internal calibration and echo source packets as well as orbit and attitude information.

The data products in this collection mirror the Sentinel-1C products provided through the Copernicus Data Space Ecosystem.
