METHOD OF CONTROL OF ORIENTATION OF SPACE TRANSPORT CARGO SHIP WITH STATIONARY SOLAR BATTERY PANELS DURING WORKS IN CONDITIONS OF ROTARY MOTION Russian patent published in 2015 - IPC B64G1/24 B64G1/44 

FIELD: transport.

SUBSTANCE: invention relates to control of orientation of a space, in particular, a transport cargo ship (TCS) with stationary solar battery panels (SB). The method includes the rotation of TCS around a normal to the working surface of SB facing towards the Sun with an angular speed of at least 1.5 deg/sec. Meanwhile within the time interval of at least one round the components of the angular speed of TCS in a structural coordinate system are measured. Using the measured values, directions of the main central axes of inertia of TCS are determined. Among these axes an axis other than the axis of the minimum moment of inertia and making the minimum angle with the normal to the working surface of SB is found. The angle between the direction towards the Sun and the plane of the TCS orbit is determined. If this angle exceeds a certain value depending on the specified minimum angle and also - on the minimum and maximum SB currents, TCS is turned. Meanwhile the named found inertia axis is combined with the direction, perpendicular to the orbit plane and making a sharp angle with the direction towards the Sun. TCS is rotated around this axis towards the direction opposite to orbital rotation. During the rotation the current from SB is measured. At the achievement by the current of the minimum value TCS is again turned until the alignment of the named found axis of inertia of TCS with the named perpendicular direction and again the named rotation of TCS is performed.

EFFECT: ensuring of the necessary power return of SB in the mode of TCS rotation around one of its actual main central axes of inertia at maintaining of the axis of the minimum moment of inertia in the orbit plane.
