The Umbra SAR constellation is an operational commercial X-band synthetic aperture radar (SAR) mission operated by Umbra, with the first satellite launched on 2021-06-30.^[1] WMO OSCAR records the UMBRA-SAR instrument as an X-band imaging radar with 1200 MHz bandwidth and 25 cm best achievable resolution, with utilisation planned from 2021 to 2035.^[2] The constellation supports multiple imaging modes including 25 cm Spotlight and Dwell modes for high-resolution tasking, as well as wider-area scan modes for large-area coverage.^[3] CEOS plans reference 32 satellites, while WMO coverage cycle documentation cites 12 satellites, reflecting evolution in programme planning.^[1]^[2] Tasking and archive access are available through the Umbra Canopy platform, which provides STAC-compatible collect metadata and programmatic ordering.^[4]^[5] Two additional satellites were added to the constellation via the SpaceX Transporter-11 rideshare in August 2024.^[6] The mission supports maritime domain awareness, disaster damage assessment, and transport infrastructure monitoring applications.
