METHOD OF SPACECRAFT SUN BATTERIES POSITION CONTROL AND SYSTEM OF ITS IMPLEMENTATION Russian patent published in 2008 - IPC B64G1/44 B64G1/24 

FIELD: technological processes.

SUBSTANCE: inventions are related to power supply of spacecrafts (SC) by means of sun batteries (SB). Suggested method includes turn of SB panels into working position that corresponds to alignment of perpendicular to their illuminated working surface with the plane that is formed by SB panels rotation axis and direction to the Sun, and turning of SB panels at the set angle between specified perpendicular and direction to the Sun. The angle of the Sun elevation above the local horizon is measured on the illuminated part of SC orbit and is compared to the value of angular SB sensitivity area semi-opening. In the moments when this angle is exceeded by this value, present value of SB current is measured and compared to the current that is generated by SB, when their working surface is oriented to the Sun, and there is no light reflecting from the Earth hitting the SB surface. When value of present current from SB is exceeding value compared to it, SB are turned from direction to the Sun to the side of the Earth centre at a certain angle so that light flows, direct and reflected from the Earth, are hitting SB. Suggested control system includes the necessary units and connections between them for performance of above mentioned operations. And it also includes unit of SC illumination moments determination, unit of SC orbit height, unit of angle measurement between directions to the Sun and horizon, unit of setting value of current from SB from direct sun radiation, unit of determination of time points of SB maximum current exceeding set value, unit of moments determination of reflected sun radiation hitting SB working surface, unit of SB turn control, and element "И".

EFFECT: increases power supply generation on board of spacecraft by means of using sun radiation reflected from the Earth.
