Guidance and gyromoment attitude control of land-survey satellite at a scanning stereoscopic observation

We have considered the problem on guidance and attitude control of a land-survey satellite during a scanning stereo-observation. For synthesis of the attitude guidance law we use our relations which connect an image motion with kinematic parameters of the satellite spatial replacement with respect to the Earth surface. Moreover the fixed values must be provided for a range of observation and angle of convergence when the scanning is carried out from two views. We present elaborated methods for the satellite angular guidance and digital attitude control by cluster of four gyrodines. We represent results of a computer simulation for stereo-surveying the two parts of the Earth surface performed by the satellite in a sun-synchronous orbit.
