Land-survey satellite guidance and attitude control when a scanning stereoscopic imagery

Abstract

The problem of guidance and attitude control for a land-survey satellite at a scanning stereoscopic imagery is considered. The synthesis of the satellite angular guidance law is based on relations that bind the image motion with the kinematic parameters of the satellite spatial motion relative to the Earth’s surface, ensuring constant values of the observation distance and angle of convergence during a scanning from two perspectives. We present the developed methods and the results of the simulation of the stereoscopic imagery fulfilled by a satellite in a sun-synchronous orbit.
