ABSTRACT

In this paper the attitude control system of a small spacecraft is considered. Reads of airborne magnetometers and satellite global positioning system (GPS) data are used for determination of the parameters of object motion. Such choice of measurements aims to raise estimations stability against disturbances of the magnetic storm type. At considerably undefined initial conditions for estimation of the desired parameters of motion we use the algorithm with an extended convergence domain.
