Sentinel-1D Single Look Complex Product Metadata
Listed in NASA Earthdata CMR
The Sentinel-1D satellite was launched November 4, 2025.
Description
Sentinel-1D is the the latest satellite to be added to the Sentinel-1 constellation. The Sentinel-1 satellites (Sentinel-1A, Sentinel-1B, Sentinel-1C and Sentinel-1D) 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-1D Single Look Complex (SLC) data products consist of focused SAR data, geo-referenced using orbit and attitude data from the satellite, and are provided in slant-range geometry.

Slant range is the natural radar range observation coordinate, defined as the line-of-sight from the radar to each reflecting object. The products are in zero-Doppler orientation, where each row of pixels represents points along a line perpendicular to the sub-satellite track. The products include a single look in each dimension using the full available signal bandwidth and complex samples (real and imaginary) preserving the phase information.
The products have been geo-referenced using the satellite’s orbit and attitude data and have been corrected for azimuth bi-static delay, elevation antenna pattern, and range spreading loss. The products in this collection are ISO compliant XML metadata created by the Alaska Satellite Facility Distributed Active Archive Center from the associated Sentinel-1D SAFE format product. Users are encouraged to review the plans for the transition to Sentinel-1D as it takes over Sentinel-1A duties at dataspace.copernicus.eu/news/2026-5-28-sentinel-1-orbital-reconfiguration-dates
