XpressSAR: High Revisit, High Resolution, All Weather SAR Satellite Constellation
XpressSAR Inc. is an American owned and operated company. XpressSAR will be a constellation of four small Synthetic Aperture Radar (SAR satellites with an average revisit rate of less than 4 hours. XpressSAR will act as a watchful eye in space over any location in its coverage area. It will be able to monitor harbors, airfields, active volcanoes, spreading floods, oil spills, ship traffic, and other sites and activities, with a periodicity of days or even hours.
Satellites will be placed in two orbit planes with a 35° inclination.
XpressSAR images can be used for automated change detection. XpressSAR can monitor the location you care about and change detection apps will alert you when something significant has occurred.
XpressSAR will have a range resolution, spotlight images with resolutions under 1 meter, to large-area strip map images with resolutions of 2 to 3 meters, to an ocean scan mode that can be as large as 300 km across and 2000 km long with resolutions of 10 to 30 meters.
XpressSAR images will provide ground coordinates that match the pixel scale of the image. No post-processing needed.
Recently the National Environmental Satellite, Data and Information Service of the National Oceanic and Atmospheric Administration, an agency of the Department of Commerce, granted XpressSAR Inc. a license to operate a private, commercial, space-based, remote sensing system.
