METHOD OF CONTROLLING BOOSTER UNIT ON ACCELERATION TRAJECTORY Russian patent published in 2011 - IPC B64G1/24 G05D1/08 

FIELD: transport.

SUBSTANCE: invention relates to control over booster unit in placing it into orbit. In compliance with this method, with booster unit separated from carrier rocket, its motion is forecast for four successive time intervals. First of said intervals is passive interval till preset initiation of engines to correct fuel ramming pulse. Second interval extends to sustainer start, third interval extends to start of booster orientation program variation, and fourth extends to moment booster reaches preset power at. At this very moment, departure from preset orbit is defined from radius, radial speed and normal to orbit plane. Sensitivity of said departures to variation in initial angles of orientation program and to their variation rate is determined. Then, computed are corrections to booster orientation program by pitch, and yaw angles and their variation rates. New corrected parameters of orientation program are determined to turn booster to said angles to reach refined initial magnitudes. Booster lengthwise axis is stabilised in orientation by this angles to executing cored orientation program.

EFFECT: optimum orientation of booster unit after its separation from carrier rocket.
