Abstract

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.
