Umbra designs, manufactures, and operates a commercial Synthetic Aperture Radar (SAR) satellite constellation, providing high-resolution Spotlight and Scan imagery with resolutions as fine as 25 centimeters. Umbra’s proprietary satellite and antenna architecture is designed to provide high antenna gain and strong signal-to-noise performance, enabling very high-resolution SAR imaging while maintaining radiometric quality and geolocation accuracy suitable for scientific applications. Umbra’s SAR data is particularly well suited for applications requiring all-weather, day-night imaging capability, including cryosphere and glacier monitoring, flood and disaster response, geohazard assessment, coastal change detection, and land-cover change analysis.
