Abstract

An image velocity stabilization system built into a space telescope for scanning optoelectronic observation of terrestrial targets with a physical hysteresis of a piezoceramic drive is considered. Elaborated algorithms for discrete filtering, results on analysis of the image motion velocity stabilization as well as technologies for terrestrial and in-flight verification are briefly presented.
