Abstract

Some problems on robust gyromoment motion control of agile spacecraft (SC) for remotesensing the Earth surface are considered. Elaborated methods for dynamic research of theSC programmed angular motion at principle modes under external, structural and parametricdisturbances, partial discrete measurement of the state and digital control of the gyromoment cluster by the minimum-excessive gyrodine scheme, are presented.
