SPACECRAFT CONTROLLING METHOD WITH HAVING ONE DEGREE OF FREEDOM SOLAR BATTERIES Russian patent published in 2019 - IPC B64G1/44 

FIELD: space equipment.

SUBSTANCE: invention relates to the spacecraft (SC) and installed on it solar panels (SB) with perpendicular to the SC longitudinal axis (X) axis of rotation (Y) orientation control. By the orbit height determining the turns range when angle (β) between direction (S) to the Sun and SC (1) orbit plane (4) exceeds value, at which the turn shadow part duration is equal to time of heat removal from the SC surface preset section (3). To the range initial turn turning the SC by angle (α) from perpendicular (Sn) to plane (4) provided that angle between S and Sn is sharp. At that, maintaining the α < 180° – β – arctan (D/L) angle, where D is section (3) distance from Y axis; L is SB length (2), and angle between Sn and the Y axis is less than 90°. When passing the terminator, the X and Y axes are oriented so that the SB was shading section (3). In the maintained SC orientation (including relative to the orbital velocity V), acting on the SC external disturbing moment is provided as minimal.

EFFECT: technical result consists in ensuring using the SB of the SC surfaces areas shading required mode.
