SYSTEM OF CONTROL OF SPACECRAFT SOLAR BATTERIES POSITION Russian patent published in 2008 - IPC B64G1/44 B64G1/24 

FIELD: transport.

SUBSTANCE: system contains solar batteries (SB) turning device, amplifying-transforming device, SB solar-orientation control block, SB preset position alignment block, current controller block, current sensor, power system control block. System additionally includes devices for measuring: spacecraft (SC) orbit altitude measuring, SC orientation, Sun elevation angle over Earth horizon visible from SC. There is also block assigning maximum value of current produced by SB under influence of direct solar radiation and blocks determining: moments of ingress of radiation reflected from Earth on rear side of SB, moments of generation by SB of additional power under influence of radiation reflected from Earth, turning angle of SB, and area of SB work surface lit by solar radiation. The circuit also includes two keys and elements "NOT" and "OR".

EFFECT: increase of solar battery electric power output by more complete use of solar radiation reflected from Earth.
