Capella Space

Introduction

Capella Space images are acquired by seven very high resolution radar satellites on an intra-day basis anywhere on the globe. The datasets are available starting with 2020.

This collection provides catalog and tasking data. See more on the marketplace.

Data product specifications

Data product type	Description
Single Look Complex (SLC)	Both amplitude and phase of SAR signal available. Range-compressed, focused image in slant-range geometry. Georeferenced using orbit data and Range-Doppler projected. Suitable for SAR experts that need phase information for coherence analysis.
Sensor Independent Complex Data (SICD)	Both amplitude and phase of SAR signal available. Range-compressed, focused image in slant-range geometry. Sensor independent format.
Geocoded Ellipsoid Corrected (GEC)	Only amplitude information available. Range-compressed, detected, focused, multi-looked image with enhanced radiometric resolution. Resampled and projected onto WGS84 ellipsoid with average scene center height. UTM and UPS projections.
Geocoded Terrain Corrected (GEO)	Only amplitude information available. Range-compressed, detected, focused, multi-looked image with enhanced radiometric resolution. Terrain-height corrected using high resolution Digital Elevation Model (DEM). UTM and UPS projections.
