METHOD OF CONTROL OF SPACECRAFT TURN Russian patent published in 1999 - IPC

Abstract RU 2131832 C1

FIELD: space engineering; effective control of spacecraft and orbital station attitude. SUBSTANCE: method includes acceleration of spacecraft, its free rotation, determination of parameters of corrective turn, functions of power consumption and rate of corrective turn at movement when this function is minimum, rotation of spacecraft at this rate and deceleration of spacecraft of spacecraft. Angles of turn of space craft are compared at the stage between acceleration and corrective turn with present and initial magnitudes, and well as with present and preset final attitude; at the moment when these angles are equal, present attitude of spacecraft is compared with predicted magnitude corresponding to similar equality for calculated trajectory of turn. In case these attitudes of spacecraft do not coincide, motion of spacecraft is corrected by shifting it to target attitude (taking into account given noncoincidence) by imparting angular moment increment (if necessary) to spacecraft for subsequent free rotation towards given target position. EFFECT: increased economical efficiency of turning maneuver. 5 cl, 2 dwg
