SPACECRAFT TURN CONTROL SYSTEM Russian patent published in 2003 - IPC

FIELD: automatic control of non-stationary objects, mainly space objects. SUBSTANCE: proposed system is used for turn of spacecraft to required attitude. Proposed system includes control jet engine unit and setters for setting angle of turn, permissible angular velocity and minimum acceleration which are interconnected in definite manner, modulus determination unit, multipliers and computer units. System is also provided with units for selection of minimum signal of angular velocity, memory and setting time of turn, as well as functional amplifier, non-linear element, etc. Control system optimizes transient processes under condition of high instability of efficiency of control engines and parameters of spacecraft proper which are stipulated by failure of these engines, change in mass of spacecraft at burning-out of fuel in main cruise engine. EFFECT: reduced consumption of fuel at optimal high speed of response of spacecraft turns. 2 cl, 6 dwg
