Nonlinear Laws for Guidance and Attitude Control of an Agile Land-survey Satellite

Yevgeny Somov, Sergey Butyrin, Sergey Somov, Tatyana Somova
We consider problems on attitude guidance and control of the agile spacecraft for surveying the Earth surface.We present developed methods for synthesis of nonlinear guidance and attitude control laws, results on dynamic research of the spacecraft attitude control system under disturbances and digital control of the gyro moment clusters by two excessive gyrodine schemes.
