METHOD OF CONTROL OF ORBITAL SPACECRAFT (VERSIONS) Russian patent published in 2002 - IPC

FIELD: satellite orientation and stabilization systems. SUBSTANCE: according to one version, moments of inertia of satellite are equalized relative to two axes by deflection of panels of solar batteries from position of their orientation to Sun. Upon completion of scheduled or necessary work (video survey, for example) which requires neutral stability of satellite relative to its third axis, panels are returned to their initial position. According to another versions, position of solar battery panels is changed during scheduled work in such way that main moment of inertia of satellite relative to first axis exceeds that relative to second axis, thus changing the sign of gravitational torque forming resistance to rotation of satellite around third axis. EFFECT: reduced action of vibrations on sensitive equipment (for example, survey equipment) from actuating members of satellite stabilization and orientation system in the course of performing scheduled work. 8 cl, 4 dwg
