50cm resolution, Daily revisit
China has introduced a constellation of four very high resolution satellites: Superview-1 and Superview-2 in operation since December 2016, and Superview-3 and Superview-4 in operation since January 2018, providing a unique response in terms of revisit time on an identical site, only 1 day. With a recording capacity of 900,000 km², the Superview-1 constellation provides a unique service complementarity for all users of very high resolution space imagery in many fields of activity, such as industrial engineering, agriculture, mining research, monitoring of major risks, land use and urban planning. The four SV-1 satellites are agile enough for simultaneous angular and stereoscopic imaging.
