METHOD OF CONTROL OF SPACECRAFT SOLAR BATTERY POSITION AND SYSTEM FOR REALIZATION OF THIS METHOD Russian patent published in 2008 - IPC B64G1/44 B64G1/24 

FIELD: spacecraft systems for supply of power with the aid of solar batteries.

SUBSTANCE: proposed method includes turning of solar batteries to the working position corresponding to matching of normal to their illuminated surface with plane formed by axis of rotation of solar battery panels and direction to the Sun. Proposed method includes also measurement of density of fluxes of solar electromagnetic radiation and high-energy particles determining the moments of beginning of solar activity and arrival of said particles to spacecraft surface. Additional measurement includes determination of appearance of signs of negative action of particle flux on spacecraft. During these moments, onboard solar batteries are charged to maximum level. When density of particle flux exceeds threshold magnitude, solar battery panels are turned through angle between said normal and direction to the Sun corresponding to minimum action of particle fluxes on solar battery surfaces. Discharge of storage batteries is hoped to close the energy gap on board the spacecraft. At minimum permissible level of storage battery charge, storage batteries are disconnected from load. When action of particles on spacecraft is discontinued, solar battery panels are returned to working position. System proposed for realization of this method includes units and their couplings for performing the above-mentioned operations. System is provided with unit for determination of current from solar batteries, unit for determination of moments of appearance of signs of negative action of high-energy particles on spacecraft and unit for setting the permissible level of charge of storage batteries.

EFFECT: reduction of negative action of high-energy particle flux on solar battery working surface due to maximum increase of angle of "protective" turn of solar batteries from direction of these fluxes to the Sun.
