METHOD OF COSMIC VEHICLE SOLAR BATTERIES POSITION CONTROL AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC B64G1/44 

FIELD: transport; heating.

SUBSTANCE: method includes turning of SB at pre-set angle between normal to SB work surface and sun direction. At that the angle between Sun direction and cosmic vessel (CV) orbital plane is measured. At moments when completion of 90° angle of visible half-spread of Earth exceeds the said measured angle and on condition CV is located at Sun-lit part of orbit, the angle between Sun direction and local vertical and Sun elevation angle over visible from CV Earth horizon are measured. In case the said elevation angle exceeds 90°, the moments of penetration of the Sun radiation reflected from Earth on back side of SB panels are determined. The current produced by SB is measured and if it exceeds value of current produced by SB with work surface perpendicular and if the sunrays reflected from Earth fail to reach, SB are turned away from Sun direction. Turning away is performed until position is reached at which the current produced by SB from direct Sun radiation on their work surface and the one produced by the sunrays reflected from Earth on back side of SB panels reach maximum possible value at the current position of CV on orbit. The suggested control system includes units and interconnections between them necessary for performance of the above-described operations.

EFFECT: increase of solar batteries power output by rational use of sunrays reflected from Earth on back side of SB panels.
