Capella Space announced May 13 that it signed a deal to provide synthetic aperture radar to the U.S. Navy, even though the company has yet to put a satellite on orbit.
Unlike traditional electro-optical satellite imagery, which can be degraded or denied by adverse lighting conditions or weather, SAR creates images with radar, meaning it can produce images regardless of the weather or lighting conditions. Additionally, SAR sensors can provide data on material properties, moisture content, precise movements, and elevation, meaning that SAR can be used to build 3D recreations of a given geographical area. Capella says its planned SAR satellite constellation will be able to collect sub-0.5 meter imagery, capable of identifying various types of aircraft or vehicles at ground level.
Still, the company has yet to put a single payload of their planned 36 satellite constellation on orbit.
