Satellite guidance and attitude control during the areal geodetic surveying

The problems on synthesis of the guidance laws and algorithms for digital attitude control for an observation spacecraft at the areal geodetic surveying are considering. The land-surveying is carried out by a set of extended orthodromic routes of scanning optoelectronic observation for a given part of the Earth surface. Results on the efficiency of the developed vector guidance laws, algorithms for discrete filtering and digital gyromoment control of a satellite orientation during the areal surveying from sun-synchronous orbit are presented.
